Opis:
A geophysical survey of basement complex using electrical resistivity method was carried out so as to provide geological and geophysical information on the different subsurface features. The sought-for parameters include thickness, depth, basement for groundwater potential and aquifer protective capacity. The acquired data were process using Win-Resist software and surfer 8, and the result was then analyzed and interpreted. Accordingly, 3-4 geoelectrical layers within the subsurface delineate the area: top soil, lateritic layer, weathered/fractured layer and fresh rock. Resistivity values of the top soil range between 55.5 mΩ to 749.7 mΩ, with average thickness of 0.4 m to 3.6 m, while the lateritic layer ranges between 153.3 mΩ to 862.0 mΩ, with average thickness of 4.5 m to 20.7 m, the weathered/fractured layer in turn ranges between 15.6 mΩ to 698.9 mΩ, with average thickness of 7.7 m to 55.2 m, and the fresh rock ranges between 13.4 mΩ to 5102 mΩ, with infinite homogeneous half space. Over all, the longitudinal conductance of the overburden units range from 0.147 mhos to 0.957 mhos and the overburden is thick enough for groundwater exploration activities. The results provide reasonably information that the aquifer units are weathered/fractured layers with a significant groundwater potential that is free of contamination.

Opis:
Bathymetry, gravity, and magnetic data across the Central Indian Ocean Basin (CIOB) along a WE track between 5°N to 1°N latitudes and 77°E to 90°E longitudes are used to identify crustal deformation due to tectonic features such as the Comorin Ridge, 85°E ridge, Ninety East Ridge, and major fracture zones. The tectonic features were interpreted along the North Central Indian Ocean using 2D gravity modelling to understand the origin and tectonic activity of the subsurface features. The Comorin Ridge is coupled with gravity anomalies with small amplitude varying 25–30 mGal in comparison with the ridge relief which suggests that the ridge is compensated at deeper depths. The focus of the present study is to prepare a reasonable crustal model of the Central Indian Ocean using gravity and magnetic data. The crustal depths of the Central Indian Ocean Basin (CIOB) determined from gravity data using the spectral method are compared with the 2D gravity modelling results. It has been observed that the crustal depths obtained from the Spectral method are in good correlation with results obtained from 2D gravity modelling. The average basement depths for the profiles were obtained as ~5 km and perhaps deviated approximately 1–2 km from the mean. In the case of curie isotherm, the crustal depths vary 9–12 km for all magnetic profiles which may indicate deformation.

Paleozoic Platform

Caledonides
Opis:
The Paleozoic Platform comprises the southwestern half of the Polish territory, separated from the Precambrian East European Platform (EEP) by a NW–SE trending subvertical lithospheric-scale discontinuity – the Teisseyre-Tornquist Zone. In the present study, the Paleozoic Platform basement is subdivided based on geological and geophysical evidence acquired during the last decades, including deep seismic refraction and reflection results, as well as gravity, magnetic and magnetotelluric data. The units adjacent to the EEP, the Mid-Polish Domain (comprising the Łysogóry Block) and the Pomeranian Block, are characterized by a thinned three-layer EEP-type crystalline crust (age 1.7–3.7 Gy). Their oldest platform cover is probably composed of thick Ediacaran syn-rift sedimentary and volcanic rocks. Their western extension in the contiguous German and Baltic area can be traced as far as the East Elbian Massif and Thor Suture based mainly on magnetic anomaly patterns. The Upper Silesian and Małopolska blocks located in SE Poland are characterized by Cadomian (660–600 My) basement overlain by the thick deformed Ediacaran foredeep deposits. Whereas the units with the EEP-type basement are interpreted as proximal terranes displaced along the EEP margin during the late Early Paleozoic, the blocks with a Cadomian basement are conceived as exotic terranes of a possible Gondwanan provenance. All these terranes were accreted ultimately during the final, latest Silurian stages of the Caledonian deformation although the exact scenario of the amalgamation remains hypothetical. The Sudetic Domain in SW Poland is a collage of different crustal units juxtaposed ultimately in the Pennsylvanian (ca. 310 Ma) during the final episodes of the Variscan Orogeny. Their northern boundary corresponds to the Rheic Suture traceable in magnetic and gravity anomalies pattern along the northern margin of the Wolsztyn–Leszno High, and continuing westwards along the Mid-German Crystalline High. The arcuate trace of the suture in the NE is dextrally displaced along the Odra Fault, and continues southwards where it is mapped as the Moravian–Silesian Suture.

Opis:
The Paleoproterozoic Mid-Lithuanian Suture Zone represents one of the major structures of the crystalline basement of Lithuania, separati ng the West Lithuanian and the East Lithuanian domains. This zone has shown persistently low tectonic activity during the Phanerozoic. The Mid-Lithuanian Suture Zone is marked by a distinct Middle Lithuanian topographic low underlain by a trough in the sub-Quaternary surface that suggests the morphotectonic nature of this depression. This is supported by high-precision geodetic level l ing data that has unravelled the subsidence trend of the Middle Lithuanian trough. The zone is also distinct in its pattern of topographic lineaments. The persistence of the tectonic activity of the Mid-Lithuanian Suture Zone suggests that it represents a large-scale mechanical boundary of the Earth's crust, resulting in increased accumulation of tectonic strain.

Since the mid-1950s, when Jerzy Znosko started his huge contribution to the recognition of the crystalline basement of NE Poland, many different studies have followed the planned and implemented drilling projects. The drillings, conducted in the first decade under the leadership of Professor Znosko and under his description of the results, were further worked out by other researchers. Studies concerned petrological, geochemical and miner- alogical aspects. In that fan of methods applied, geochronological data started to be introduced to the bibliography of the area in the early 1960s. Geochronological methods that time mean mostly K-Ar and some Rb-Sr values. These materials are gathered in the paper aiming at its presentation, re-valuation and interpretation in terms of the significance of such data for further development of knowledge.

Opis:
Krynica Spa is situated in the southern part of the Magura Nappe, at the boundary between the Bystrica and Krynica subunits. The Bystrica succession is composed of the Middle to Upper Eocene strata of the Magura Formation, while the Krynica succession is built up of the Palaeocene through Middle Eocene strata that belong to the Szczawnica, Zarzecze and Magura formations. The Bystrica and Krynica subunits contact along a sub-vertical, NE-dipping fault. In the study area, several NE-trending transversal faults cut both the Bystrica and Krynica subunits into several blocks. The Krynica area is seismically active, as shown by the most recent, moderate- intensity earthquakes which occurred in 1992-1993, of epicentres situated NE of Krynica Spa. The region is rich in natural mineral water springs which are confined to a tectonic block bounded by the Tylicz and Krynica faults.
Uzdrowisko Krynica jest usytuowane w południowo-wschodniej części płaszczowiny magurskiej na styku podjednostki (bystrzyckiej) i krynickiej (Fig. 1). W badanej przez nas zlewni Kryniczanki utwory strefy bystrzyckiej występują jedynie fragmentarycznie, w NE części obszaru badań. Do strefy bystrzyckiej (sądeckiej) należą wyłącznie utwory formacji magurskiej wieku środkowo-późnoeoceńskiego, o łącznej miąższości stratygraficznej 1150– 1250 m. Są to: ogniwo z Maszkowic (piaskowce gruboławicowe z przeławiceniami margli łąckich), ogniwo łupków z Mniszka (łupki pstre i cienkoławicowy flisz) oraz ogniwo piaskowców popradzkich ("piaskowce zuberowskie"). Strefa krynicka reprezentowana jest przez paleoceńsko-środkowo-eoceńskie utwory formacji szczawnickiej (cienko- i średnioławicowy flisz), zarzeckiej (cienkoławicowy flisz z ogniwem piaskowców krynickich) oraz magurskiej (piaskowce gruboławicowe). Niepełna miąższość utworów strefy krynickiej wynosi co najmniej 1300 m. Podjednostki bystrzycka (sądecka) oraz krynicka kontaktują ze sobą wzdłuż pionowego lub niemal pionowego, zapadającego na NE uskoku, zwanego "dyslokacją krynicką". Uskoki poprzeczne o przebiegu NE–SW dzielą obie podjednostki na kilka bloków. Między Czarnym Potokiem a Słotwinami wąski półrów tektoniczny towarzyszy uskokowi słotwińskiemu. W okolicach Krynicy notowane były w latach 1992–1993 wstrząsy sejsmiczne. Epicentra tych wstrząsów grupują się wzdłuż uskoków poprzecznych o orientacji NW–SW oraz dyslokacji krynickiej.

Opis:
The area which transcends the Precambrian basement complex onto the Sokoto sector of the Iullemmeden basin in northwestern Nigeria presents a unique prospect for geothermal exploration research in the absence of regional heat production data, despite its tectonic history and depositional characteristics. In this study, geophysical exploration employing radiometric technique was adopted to classify the petrologic units within the fringes of the Iullemmeden basin and the adjoining crystalline basement complex so as to estimate the radiogenic heat potential within the terrain that may support geothermal considerations. Airborne radiometric measurements acquired over the area were digitized and processed to obtain radioelement concentration maps and the K/Th/U ternary map. Results show that the ranges of measured concentrations of 40K, 238U and 232Th are 4.6 to 18.9%, 0.7 to 4.9 ppm and 4.6 to 18.9 ppm respectively. Radiogenic heat estimation derived from radioelement data within eight petrologic units comprising quaternary sediments, schist, carbonates, shale/clay, younger granites, older granites, gneissic rock and migmatite showed that the lowest radiogenic heat production estimates ranging from 0.27–0.66 µW∙m−3 were recorded in the sedimentary terrain within the quaternary sediments while the highest radiogenic heat production values of between 2.04 to 2.34 µW∙m−3 were recorded in the basement complex within gneissic rocks. The spatial distribution of radiogenic heat in the area showed an increased heat gradient within the basement complex and a diminishing heat gradient over the Iullemmeded basin.

Magnetic total field measurements acquired in Poland between 1974 and 2011 have been compiled in a new digital database that provides a complete picture of magnetic anomalies of the country. The data compilation and further processing procedures used to create the magnetic anomaly database and maps that accompany this article are briefly summarized. The reduced-to-the-pole and pseudogravity anomaly maps were computed to accurately locate anomalies above their causative bodies as well as to simplify anomaly patterns and emphasize principal magnetic domains within the basement. An interpretation of the magnetic maps reveals a lot of magnetic basement provinces and domains indicating basement division into blocks and structural elements, which are important for understanding the regional tectonic setting of Poland.

Opis:
This paper reviews the tectonic genesis of the Telfer Au-Cu ore system in the Paterson Orogen, NW Australia. Most previous tectonic interpretations have focused on the regional compression-related tectonic processes. These interpretations, however, could neither explain the tectonic deformation nor the distribution of mineralisation. Tectogenetic analysis indicates that the Telfer deposit comprises two overlapping structural domains, both developed as a result of the upward propagation of basement fractures. The first domain represents a local compression-shear-related regime that initiated tectonic deformation and tectonic shortening of the host rock. This regime had a limited role in the mineralising processes. The second, more important regime for mineralisation control, is associated with local shear-extensional tectonic processes. At deposit scale, concurrent development of a normal dip-slip movement along the earlier formed bedding surfaces and the basement propagated steep reverse-slip shearing along NW-SE (S2) trending structures, parallel to the strike of the Paterson Orogen, are the most important tectonic processes of this domain. Bedding surface extensional openings and development of second order structures with N-S (E3) and NW-SE (E2) orientation controlled the tectonic genesis of the majority of orebodies and mineralised zones forming the Telfer ore system.

Opis:
A comparative sedimentological analysis of the Upper Jurassic–Lower Cretaceous deposits carried out on drill-cores from the southern part of the Carpathian Foredeep allowed us to distinguish thirteen main microfacies types. The results of microfacies analyses and stratigraphical data made it possible to propose a lithological subdivision of the southern part of the Upper Jurassic and Lower Cretaceous sediments of the Carpathian Foredeep basement between Kraków and Rzeszów. In the analysed wells, three main sedimentary complexes were distinguished, embracing the following intervals: (i) Callovian–Oxfordian, (ii) Kimmeridgian and (iii) Tithonian– Berriasian–Valanginian. The Oxfordian, Kimmeridgian and Tithonian deposits represent the outer – mid homoclinal ramp facies, whereas the Berriasian and Valanginian deposits belong to the inner homoclinal ramp facies. Complexes of microbial-sponge reefs, with a distinct relief, could be recognised in the Upper Oxfordian sediments only. The development of these buildups took place in a basin typified by diversified morphology, determined by the block-type structure of the Palaeozoic basement and synsedimentary tectonics, which brought about substantial variability in thickness of the Oxfordian sediments. At the end of the Oxfordian, large complexes of the reef facies were replaced mainly by microbial-sponge and microbial-coral biostromes developed during the Kimmeridgian and Tithonian. In the principal part of the studied area (except the western part of the described fragment of the Carpathian Foredeep; Kraków area) during the Kimmeridgian, Tithonian, Berriasian and Valanginian, sedimentation occurred in a basin typified by homogeneous morphology, which resulted in a wide extent and comparable thicknesses of the distinguished facies types. In the studied sections, indications of partial or complete dolomitization were observed in a large part of the sediments. Four generations of dolomite document a complex diagenetic history with multiple episodes of dolomite formation: from early diagenetic environment to late burial conditions.

The Precambrian basement and Lower Paleozoic (Cambrian–Ordovician) sedimentary cover in the eastern part of the Upper Silesian Block (Brunovistulicum), known only in boreholes, is presented, and their palaeogeographic, facies and palaeotectonic development is discussed. The former is characterized by a heterogeneous structure that consists of Archean-Lower Proterozoic and Neoproterozoic rocks of different lithologies and origins, and the latter is almost exclusively represented by marine, transitional and terrestrial siliciclastic rocks. In contrast to the neighbouring region of the western part of the Małopolska Block, the siliciclastic sedimentation took place during the Early and Middle Cambrian in this area, however, the Ordovician deposits were encountered in several boreholes and no Silurian rocks have been reported in the northern part of this region. The authors present the most probable model of sedimentation, tectonics and origin of the geological structure of the Lower Paleozoic sedimentary cover in the Upper Silesian Block, define research problems, and justify the need for new drillings. Based on the geological and structural analysis of the depth to the top surface of the Lower Paleozoic, they define the optimal location for three 1500 m deep boreholes to solve the basic research problems.

Opis:
In the latest Precambrian and Early Cambrian, turbidity currents and cohesive flows transported pebbles, sand and mud into a deep water in south-east Poland, this sediment probably being sourced from Gondwana. Abundant detrital albite grains suggest volcanism during sedimentation. Pebbles in conglomerate interbeds are polymict and include rock fragments showing greenschist facies regional metamorphism in the source area. The Precambrian surface in the marginal part of the Carpathians lies at 2000-5000 m b.s.l., whereas farther south, around Kuźmina it reaches 7000 m. Still farther south (Krosno-Sanok-Baligród) geophysical evidence suggests it lies at about 17-20 km depth.

Differentiation of groundwater flow conditions within the floodplains of the river valleys in the Polish Lowlands may result from polygenesis of their valleys sections, as well as from the evolution of river systems, which lasts from the end of the Pleistocene. The investigations, which were carried out in the middle Vistula valley showed that important factor for differentiation of groundwater flow conditions within the floodplain could be also the influence of the basement of contemporary alluvia. In the sections where it forms morphological protrusions, the basement affects the flood waters flow which transforms upper part of floodplain lithological profile.

Opis:
The Mid-Polish Trough formed the axial part of the Polish Basin belonging to a system of the Permian-Mesozoic epicontinental basins of Western and Central Europe. It was filled by several kilometres of siliciclastics and carbonates, including thick Zechstein (approximately Upper Permian) evaporites. TheMid-Polish Trough was inverted in the Late Cretaceous-Paleocene times, when it was strongly uplifted and eroded. The presence of thick salt significantly influenced Triassic evolution of the central (Kuiavian) part of theMid-Polish Trough where the Kłodawa salt structure is located. Analysis of seismic data calibrated by several deep wells point to three main stages of the Triassic evolution of this structure. During Early andMiddle Triassic Kłodawa salt pillow grew above the basement extensional fault zone, during early Late Triassic (approx. time of deposition of the Lower Gypsum Beds) Kłodawa salt structure reached diapiric stage and salt eventually extruded on to the basin floor. Last stage was characterised by rather uniform sedimentation and lack ofmajor saltmovements. Wojszyce salt pillow located north-east of the Kłodawa salt structure grew until the Late Triassic (approx. time of deposition of the Upper Gypsum Beds) when basement fault zone located below it was probably inverted. This inversion triggered formation of the salt-cored Wojszyce Anticline and was followed by localised erosion and rather uniform Norian–Rhaetian (Lower Kłodawa Beds) sedimentation above the anticline. Local tectonic activity below the anticline might have additionally enhanced growth of the Kłodawa salt diapir. The presented tectono-sedimentary model of the relationship between basement and salt tectonics and their influence on the Triassic depositional systems is compatible with results of analogue modelling of linked basement-salt tectonics, and with a model based on mesostructural studies completed for the Kłodawa salt mine.

Opis:
The paper presents the activity ofselected landslides where instrumental monitoring has been carried out within the Framework of Landslide Counteracting System (SOPO). The temporal relationships between subsurface dynamics (displacements) and geological structure with respect to atmospheric precipitation are discussed. In order to expose these relationships, the landslides were divided into two groups: the first one is located in the areas where the bedrock is made up of flysch formations with the predominance of clay rocks. The second group is located in areas with the prevalence of sandstones in the bedrock. The analysis of the 10-year record shows that, in the areas where the geological structure is dominated by clays, the landslides present continuous activity with displacements not exceeding a dozen mm/year. In the areas where in the geological foundation (bedrock) sandstones are dominated, landslide movements were usually more impulsive. Dislocations were recorded mainly after intense, long-lasting precipitation or heavy rainstorms. In extreme situations the large displacements caused total destruction of the measuring column.

Opis:
Within the channel zone of the Middle Vistula River, elevations of the Holocene alluvial basement occur, composed of deposits resistant to erosion. In this paper two kinds of such forms are discussed. Within the Małopolska gorge (an upstream part of the Middle Vistula, near Kępa Gostecka and Zakrzów), the elevations are composed mainly of Upper Cretaceous and Paleogene rocks covered with clayey debris and residual lags. Below this, the elevations are built of Paleogene and Neogene soils as well as of various Pleistocene glacial deposits, and are of ten covered by residual lags. This type of valley stretch occurs in the vicinity of Dęblin. The surface of the erosion-resistant Holocene alluvial basement averages at 5-7 m below the mean water level. It is exposed on the channel bottom during high-water stages, as seen from a residual layer and from the low density of the contemporary channel deposits above them. The morphology of these elevations influences the pattern of the main stream also during mean-water stages. The trend to flood flow concentrations is also seen in the relief of the floodplain.

Opis:
Quantity, genetic type and maturity of organic matter dispersed in the Lower Palaeozoic sequence from the Lower Cambrian to Silurian strata of the Polish and Ukrainian parts of the Carpathian Foredeep basement in the Tarnogród–Stryi area were evaluated based on the results of geochemical analyses of 475 rock samples collected from 45 wells. The best source rocks were found in the Silurian strata where the present total organic carbon (TOC) content is up to 2.6 wt%. They occur in the vicinity of Wola Obszańska, where the median of the present and the initial total organic carbon (TOC) contents in the individual wells amount to 0.98 and 1.6 wt%, respectively. The Cambrian and Ordovician strata have a poorer hydrocarbon potential and their present TOC content never exceeds 1 wt%. In all of the investigated Lower Palaeozoic strata, organic matter is represented by the oil-prone Type-II kerogen deposited in anoxic or sub-oxic conditions. The maturity of source rocks ranges from early mature (the initial phase of the low-temperature thermogenic processes) in selected zones of the Silurian strata in the vicinity of Wola Obszańska, through the middle and the final phase of “oil window” in the Ordovician and Cambrian strata in the Polish part of the study area, to the overmature stage in the Ordovician strata in the south-eastern part of the study area (Ukraine).

Opis:
This thematic issue of Annales Societatis Geologorum Poloniae contains a set of papers presenting results of a special research project entitled "Petroleum exploration prospectives and hydrocarbon potential of the Miocene strata and Mesozoic–Palaeozoic basement in the borderland area of Poland and Ukraine", led by research teams from the AGH University of Science and Technology in Kraków and the Polish Geological Institute – National Research Institute in Warsaw. The objective of this paper is determination of the geological and geochemical conditions, 1-D and 2-D modelling of petroleum processes and petroleum systems and their influence on the prospectives of hydrocarbon exploration of the Miocene strata in the Polish and Ukrainian Carpathian Foredeep and its Palaeozoic–Mesozoic basement. In particular, a coherent model of geological structure of the area, based both on the synthesis of the earlier published data and on new results of palynological studies of the Upper Precambrian and Lower Palaeozoic, is given. New data on microfacies of the Upper Jurassic and Lower Cretaceous strata and on sedimentology, geochemistry and micropalaeontology of the Middle Miocene rocks are presented.

Opis:
Petroleum geochemical data of 34 oils and condensates accumulated in the Carpathian Foredeep and its Mesozoic and Palaeozoic basement were used to assess their origin and genetic type. The analysed liquid hydrocarbons are characterized by variable densities and sulphur contents. No relationship between these parameters and the reservoir rock age has been found. Secondary processes of evaporative fractionation and biodegradation are evidenced for some oils. These processes proceeded most intensively on the oil from Góra Ropczycka-1K well. The oils from Opaka-1, Lubaczów-157 and Góra Ropczycka-1K wells were generated from organic matter deposited in the Upper Jurassic carbonates. The oil from the inflow in Załazie-2 well originated from the Cambrian strata, but also contains biomarkers characteristic of Miocene strata. The next family, genetically connected with the Silurian and Ordovician source rocks, consists of oils accumulated in the Lower Carboniferous carbonates in Nosówka deposit and in the Upper Jurassic in the inflow into Łękawica-1 well. The condensates collected from the Miocene (Łękawica-1, Pilzno-37, Tarnów-39 and -45 wells) and Upper Jurassic strata (Łąkta-27 and Tarnów-5 wells) were generated by organic matter dispersed in the Middle Jurassic or Lower Carboniferous clastic facies. The remaining oils, from Grobla-Pławowice, Wierzchosławice, Jastrząbka Stara, Partynia-Podborze, Dąbrowa Tarnowska, Brzezówka and Zagorzyce deposits, and the inflows into Tarnów-47 and Pilzno-12 wells were generated from kerogen enriched in organic sulphur usually dispersed in carbonate rocks. Such a type of sediments occurs in the Devonian and Lower Carboniferous strata. Also, these strata as well as the underlying Silurian rocks have sufficient maturity for generation of the discussed oils. The oleanane in the discussed oils most probably originates from kerogen of the Upper Cretaceous or Miocene strata, through which these oils migrated and eluted this biomarker.

Przedmiotem artykułu są wyniki reinterpretacji trzech regionalnych profili magnetotellurycznych zlokalizowanych w polskich Karpatach Zachodnich. Badania magnetotelluryczne w tym obszarze wykonało Przedsiębiorstwo Badań Geofizycznych w Warszawie w latach 1997-2002, Prace reinterpretacyjne poprzedzone zostały przez analizę danych pomiarowych i ich reprocessing dla wybranych sondowań. W reinterpretacji wykorzystano głównie automatyczną inwersję 2D oraz inwersję 1D przy użyciu algorytmów Occama i LSQ. Dwuwymiarowe przekroje oporności opracowane na podstawie wyników automatycznej inwersji 2D oraz interpretacji 1D wykorzystano do konstrukcji modeli geoelektryczno-geologicznych. W interpretacji geologicznej wykorzystano także informacje geologiczne i wiertnicze oraz dane sejsmiki refleksyjnej.
The subject of the paper includes results of reinterpretation of three regional magnetotelluric profiles located in the western part of the Polish Carpathians. Magnetotelluric survey in the area was made by the Geophysical Exploration Company, Warsaw, in the years 1997-2002. Reinterpretation works were proceeded by analysis of measurement data and reprocessing for some soundings. Automatic 2D inversion and 1D inversion with the use of Occam and LSQ algorithms were employed in reinterpretation process. 2D resistivity sections obtained based on results of automatic 2D and 1D data interpretation were used to construct geoelectric and geologic models. Geological and borehole data, and reflection seismic data were also applied in geological interpretation.

Opis:
The intensive development of studies on the crystalline basement of the Polish part of the East European Platform started only in the mid-1950s. These studies were based on geophysical research that preceded planned deep drilling projects. Twenty-five drill holes were located along four sections called: Białowieża, Kruszyniany, Sokółka and Krasnopol. The aim of this article is to re-evaluate drilling materials in the light of a variety of data, mainly structural data obtained from 20 boreholes from the first three "drilling sections”. All these sections were located on the Belarus-Lithuanian Elevation where the crystalline basement occurs at the shallowest depths. Special attention was paid to the recognition of ductile shear zones, SM foliation, LM mineral lineation and kinematic indicators. The results of the studies made it possible to identify the direction of tectonic transport, mainly with the top-to-SW, S and W, and deformation regimes in the boreholes of the Podlasie Belt. The main deformations have been related to a compressional regime in the amphibolite and granulite facies of regional metamorphism during the Svecofennian orogeny. It is suggested for the future to combine the research efforts of specialists from different fields of geological sciences. However, due to the scarcity of core material from old drillings, the most important are new deep boreholes that will provide a lot of drilling material to explain the geological structure and the evolution of the Proterozoic basement of NE Poland.
