Opis:
In the north – western part of Kosovo, the next lito stratigraphic units were separated: Palaeozoic (gneiss, mica schists, leucogneiss, amphibolite, quartzite), Jurassic (Serpentinised hazburgit, Schist serpentines with granitic intrusion, Basalts with dacite dykes, Dacite, Metamorphic sole (amphibolites), Supra ophiolite sedimentary mélange), Cretaceous (Valanginian basal conglomerates, Valanginian–Hauterivian silty – sandstone turbidity’s, Barremian–Aptian basal conglomerates, Barremian–Aptian silty – marl turbidity’s, Albian–Senomanian sandy – phillitic turbidites, Santonian sedimentary ophiolitic melange) Quaternary (alluvium, proluvium, slope wash, lower river terrace, higher river terrace, lacustrine, gravel and sand). The samples were taken from those rocks for chemical, geo-chemical and for the preparation of petrographic microscope properties. The analyses were completed at the certified laboratory of Geology-Mining Faculty (Polytechnic University of Tirana) – Geosciences Institute.

Opis:
It seems that the only correct way to identify impact craters is a combination of theoretical analysis, visual observation and experimental analysis, which are inextricably linked to the environment in which the crater was formed. Undoubtedly, the shock metamorphism is an essential diagnostic tool for the identification of the crater. The depth of water is a major problem in the formation of the marine craters.

Opis:
Cassiterite and base-metal mineralisation from the Gierczyn mine on the Karkonosze-Izera Massif, Poland has been studied using electron microprobe and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) techniques in order to determine the content of indium in the ore minerals. The main carriers of this element are sphalerite (up to 433 μ/g of In), chalcopyrite (up to 117 μ/g of In) and cassiterite (up to 0.02 wt.% In). Trace element contents of sulphides, especially Ga in chalcopyrite intergrown with sphalerite in comparison with chalcopyrite without sphalerite, may indicate metamorphic re-equlibration and suggests that the ore minerals might recrystallized and underwent metamorphism in conditions of greenschist/amphibolite facies. Although the deposits in the Stara Kamienica Schist Belt are not of economic value, they can contribute to better understanding of the relations between trace element partitioning and the formation of ore minerals.

Opis:
Petrographic and microtextural analyses were done on the thin section of an impactite from the Jacek Siemiątkowski Collection of Meteorites (ING PAN OB Wrocław). Two types of textures, crystalline and glassy are distinguishable. In each of them, mineral and rock fragments are deformed in different way and to various degree. One can distinguish: biotite kink bands, irregularly fractured quartz grains, twins of feldspar crystals. Moreover there are visible textures such as planar deformation features in quartz and feldspar grains, diaplectic and polymineral – lechatelierytic glasses. All the observed textures may testify the origin of the rock. The slightly deformed fragments and strongly deformed ones developed during the compression phase of the crater formation at different distance from a projectile and the crater centre. This event was followed by excavation of deformed material and its redeposition in the crater filling. The rock was recrystallised afterwards, which is inferred from the presence of the decorated PDFs and subgrains in some dynamically recrystallised quartz grains.

Opis:
The Dardanian zone represents the western part of the Rhodope crystalline basement. This zone was structured and metamorphosed during the Hercynian and post Hercynian tectonic stages. The important aspects have been identified in the structure and metamorphism from this part of western Rhodopes. The geological setting of study region has clarified the most important aspects regarding: structural geology, deformation, tectonics, and metamorphism. The studied region represents an important node in the geology of Kosovo and beyond. In this region there is the border of the Vardar unit and the Serbo-North Macedonian tectonic unit (Dardania Massif). The Serbo-North Macedonian Massif (eastern part of Kosovo) structurally represents the upper part of Dacia and the innermost whole, compared to the Carpathian-Balkanids described above. The Crystalline belt of metamorphic rocks belongs to high-grade metamorphism. The rocks of the Upper Complex represent a volcano-sedimentary sequence that is metamorphosed only under greenschist facies conditions. The Lower Complex consisting of gneiss, micaschists and to a lesser extent amphibolites, quartzites, marbles and migmatites. The main event of the Hercynian tectonic period that structured the rocks forming in the Dardania zone is associated with the regional deformation D2. Its intensity is depending on the type of rocks, but it is noted an increase of the intensity from west to east. The associated schistosity S2(penetrating schistosity)is an axial plane schistosity of the isoclinals folds S0, S1. The schistosity S2 is homogenous, with an average strike direction of 345° and dip direction of 45°. The intersection lineation (L2) and the fold axis (B2) are very homogenous with the dip azimuth toward N (350°) and dip angle of 10°. The deformation D3 is associated with the crenulations of schistosity S3. The schistosity S3 represents the axial plan of the kink fold and crenulation. The schistosity S3 is very heterogeneous and it is difficult to arrive at conclusions regarding the average direction of this planar structure also to judge the kinematic aspects of the movement. Likewise, the axis of the crenulations B3 and L3 lineation represent relative heterogeneous linear structures. The deformation D4 is associated with the fracture schistosity S4. The schistosity S4 often show the axial plan of the open parallel folds. The schistosity S4 is homogenous with the range East–West with symmetric drop (in the N and S), by proving that we are dealing with a phase of deformation with an extensional tectonic regime (with the direction N–S).

Opis:
The structure and evolution of the Polish part of the Variscan Orogenic Belt is reviewed, based on published data and interpretations. The Sudetic segment of the Variscides, together with adjacent areas, experienced multi-stage accretion during successive collisional events that followed the closure of different segments of the Rheic Ocean. In SW Poland, Variscan tectono-stratigraphic units are tectonically juxtaposed and often bear record of contrasting exhumation/cooling paths, constrained by palaeontological and geochronological data. This points to the collage-type tectonics of this area. A three-partite subdivision of the Sudetes is proposed that reflects timing differences in deformation and exhumation of the respective segments. The Central,West and East Sudetes were deformed and amalgamated during the Middle/Late Devonian, at the turn from the Devonian to Carboniferous and during Early Carboniferous times, respectively. Problems in extending the classical tectono-stratigraphic zonation of the Variscides into the Sudetes are discussed and attributed to activity along Late Palaeozoic strike-slip faults and shear zones, disrupting and dispersing the initially more simply distributed tectono-stratigraphic units into the present-day structural mosaic. Relationships between the Variscan Externides and the foreland basin are explored. Sediments of the foreland basin locally onlap the external fold-and-thrust belt that had undergone an earliest Carboniferous partial tectono-thermal overprint. During the Late Carboniferous, the SW part of the foreland basin was heavily affected by thrusting and folding and incorporated into the Externides. DuringWestphalian C to Early Permian times, localized folding and thrusting affected the distal parts of the foreland basin, probably in response to dextral transpressional movements along NW–SE trending basement faults.

P-T conditions of the Alpine regional metamorphism of carbonate successions which form the cover sequence of the southern Veporicum crystalline basement have been determined. The P-T estimates were calculated on the basis of microprobe chemical analyses of equilibrium mineral assemblages together with analyses of bulk rock chemical composition. The calibrated geothermic reactions Cal-Dol and Kfs-Phl were used. Geothermometric and geobarometric data were obtained using the SOLVCALC, TWQ and PERPLEX software programs in combination with phengite geobarometry. The metacarbonates were formed from a sedimentary-carbonate protolith in low-pressure and low-temperature conditions of greenschist facies in the kyanite stability field: TCalAb-Or

Opis:
Two ordinary chondrites are compared and classified using transmitted and reflected light microscopy and electron microprobe analyses. Both meteorites were confiscated by the Polish Customs Service at the border with Belarus. The first meteorite (called in this paper Terespol-1) is a L/LL6 chondrite, its classification being supported by the equilibrated compositions of olivine and orthopyroxene and the presence of large recrystallized feldspars (< 150 μm). The specimen examined experienced weak shock metamorphism (S3) and moderate weathering (although metal in the inner part of the meteorite seems to be unaffected by oxidization). The other meteorite (called in this paper Terespol-2) is a LL6 chondrite which experienced weak shock metamorphism (S3) and is unaffected by weathering. The Terespol-2 meteorite shares its classification with the Dhofar 1401 chondrite but the lack of data prevents further correlation. Both meteorites have been correlated with known findings from the Meteoritical Bulletin database and an attempt is made to identify their place of origin (fall event). Results indicate that Terespol-1 is most closely related to the Dhofar 1316 chondrite and we suggest that both meteorites at least came from the same parent body.

Opis:
An amoeboid olivine aggregates (AOA) are the refractory end-member of a family of fine-grained inclusions. They consist of masses of fine-grained (generally forsteritic) olivine crystals with other phases dispersed in between. The AOA are important components of carbonaceous chondrite and have been reported only from the unequilibrated Semarkona LL3.0 ordinary chondrite and examined by author equilibrated Sahara 02500 ordinary chondrite. The AOA’s are thought to represent solar-nebula condensates that experienced high-temperature annealing, but largely escaped melting. An amoeboid olivine aggregate found in the equilibrated ordinary Sahara 02500 chondrite has experienced weak planetary metamorphism resulting in equilibration and recrystallization of fine-grained olivine and albitic feldspar. The aggregate contains several fine-grained inclusions consisting of recrystallised fayalitic olivine, feldspar and minor amounts of metal, diopside, chromite, and apatite.

Opis:
Extensive zone of thermally altered sedimentary rocks occurring in the contact aureole of granodiorite intrusion has been described from the boreholes in the Będkowska Valley near Kraków. Depending on the composition of primary rocks and the distance from the intrusion the following metamorphic rocks were formed: fine-grained cordierite hornfelses, macroscopically spotted andalusite hornfelses, chlorite-bearing spotted rocks, metaconglomerates, metasandstones and metamudstones. These rocks consist of various neogenic minerals: cordierite, andalusite, biotite, muscovite, feldspars and corundum. The rocks and neogenic minerals have been investigated in details using optical and electron microscopy, X-ray diffraction, EDS and chemical methods (ICP, INAA, XRF). Characteristic contact metamorphic mineral paragenesis suggests that the most altered rocks in question were formed within temperature range from 580 to 630°C and pressure about 1-2 kbar under conditions corresponding to the orthoclase-cordierite hornfels facies of thermal metamorphism.
Rozległa strefa przeobrażonych termicznie skał osadowych tworzących aureolę kontaktową dookoła intruzji granodiorytu została opisana z wierceń (otwory DB-5 i WB-102A) usytuowanych w Dolinie Będkowskiej (na północny zachód od Krakowa). W zależności od odległości od intruzji oraz pierwotnego składu mineralnego i chemicznego skał osadowych, podczas metamorfizmu kontaktowego powstały następujące skały: drobnoziarniste hornfelsy kordierytowe, makroskopowo plamiste hornfelsy andaluzytowe, skały plamiste z chlorytem, metazlepieńce, metapiaskowce i metamułowce. W badanych skałach stwierdzono występowanie następujących neogenicznych minerałów: kordierytu, andaluzytu, biotytu, muskowitu, skaleni i korundu. Skały przeobrażone termicznie, oraz ich neogeniczne minerały zostały szczegółowo przebadane mikroskopowo (mikroskop polaryzacyjny i elektronowy), metodą rentgenowską oraz metodami chemicznymi (klasyczna analiza chemiczna, ICP, INAA, XRF oraz EDS i mikrosonda). Obecność w badanych skałach paragenez mineralnych charakterystycznych dla facji ortoklazowo-kordierytowo-hornfelsowej metamorfizmu kontaktowego (według terminologii Winklera) może sugerować zakres temperatur (580-630°C) i ciśnień (1-2 kbar), w którym doszło do najintensywniejszej termicznej transformacji skał osadowych.

Opis:
Our studies focus on ore mineralization in a contact-metamorphic aureole, using the Variscan Karkonosze Granite pluton as an example. The Karkonosze in trusion is enveloped by an Early Palaeozoic (about 500 Ma) metamorphic complex of the Izera–Kowary Unit composed of a diverse assemblage of gneisses, granitic gneisses, schists, amphibolites and marbles. The Budniki ore mineralization site was discovered in the early 1950's at the SE margin of the pluton. The uneconomic Ti-ox ide/sil i cate, Fe-Cu-Ni-Co-sulphide-sulphoarsenide, and uranium mineral deposits are hosted within amphibolites which were subjected to regional metamor phism fol lowed by contact meta - morphism. The Ti mineralization includes an ilmenite-titanite assemblage that originated from regional-metamorphic transformation of igneous Ti-bearing minerals, such as ilmenite and tschermakite, of the basic protoliths of amphibolites. During subsequent contact metamorphism, ilmenite was decomposed and, after wards, Al-rich titanite and rutile were formed. The Ti remobilization was coeval with an early stage of superimposed Fe-Cu-Ni-Co-sulphide/sulphoarsenide mineralization (pyrrhotite, pyrite, pentlandite, arsenopyrite, chalcopyrite, sphalerite and Fe-Ni-Co-As-S phases), related to the activity of the Karkonosze Granite hydrothermal system. The ore minerals formed successively within a wide range of temperatures (625–250gradeC).
