Opis:
During the period of intellectualferment in 1980-1981 the "Solidarity” Commitee at the Geological Institute elaborated and proposed main guidelines for a reorganization of the Polish Geological Survey. The project, following wide discussion in the Polish geological community, was designed according to standards implemented in leading Western countries. The proposal assumed that the survey should maintain a high scientific level and ought to be independentfrom any direct political influence or pressure ofeconomic lobbies. While organization details proposed in the "Solidarity” project may be disputable, its general premises remain up to date.

Opis:
The Geological Quarterly has come a long way since the first is sue was published in 1957 under the Polish title Kwartalnik Geologiczny. From a local bulletin publishing studies of the Pol ish Geological Institute it has became an international journal, in dexed since 2003 by the Institute for Scientific Informa tion. The impact factor for 2006 was 0.846, a considerable increase (IF2005 - 0.325) representing upgrading in the "Geology" category to 22nd position among 36 journals ranked. Despite the growing significance of regional geoscientific journals, the Geological Quarterly will face new challenges in coming years due to competition from other periodicals, including those from Central and Eastern Europe. The global tendency of limiting the paper is sues of journals in favour of electronic versions will enforce changes inediting and distribution. Better rankings of the journal lead to a growing submission rate, associated with increased risk of dealing with manuscripts including duplicated material.

Opis:
The Polish part of the Central European Variscan foreland includes several regional units that differ in crustal structure and are characteried by distinct Devonian to Carboniferous subsidence and depositional histories. These units responded differently to palaeostress changes along the south ernmargin of the Old Red Continent. During the Devonian to Namurian A, areas located to the south-west of the Teisseyre-Tornquist Zone (TTZ), including the Upper Silesian Coal Basin, Małopolska and Łysogóry-Radom blocks, were influ nced by stress fields similar to those in the west ward adjacent Rheno-Hercynian Zone, whilst the Lublin Basin, located to the north-east of the TTZ, shows a similar development to the Pripyat-Dniepr-Donets rift system. After the Namurian A, the entire southern Pol ish foreland started to respond in a more consistent way to the build-up of synorogenic compressional stresses, implying a more uniform development of the stress field. During the Namurian B to early Westphalian D, the Polish foreland was dominated by north-directed compressional stresses emanating from the Southeastern Variscan Belt. During the late Westphalian and early Stephanian, the entire foreland under went compressional deformation and concomitant basin in version under the influence of stresses propagating from the Moravian-Silesian Foldand-Thrust Belt. In the Polish foreland, the development of Devonian-Carbon if erous basins, as well as the architecture of Variscan structures, clearly reflect the reactivation of preexisting crustal discontinuities, including specifically the TTZ, but also other major geophysically defined crustal bound aries. In general, thick-skinned tectonics controlled by the inherited structural grain of the basement prevailed, whereas structural decoup ling, resulting in the development of minor thrusts and reverse faulting, was of local significance only. The distinct structural-depositional development of the Pomerania region reflects its distal location with respect to the evolving orogen. Orogenic compression influenced this area only indirectly, with the TTZ acting as a guide for the transmission of transtensional and transpressional stresses.

Opis:
The Łysogóry Block (ŁB) exposed in the northern Holy Cross Mts. (HCMts.) reveals subsidence and thermal development consistent with the pattern observed in adjoining East European Craton (EEC) areas. This evidence, in addition to previously reported similarities in sedimentation and deep crustal structure, contradicts the Pożaryski's hypothesis that the Łysogóry Block represents a terrane within the Caledonian orogen. This area is here interpreted as the part of a Late Silurian foredeep basin which developed on the Baltica margin in response to terminal phases of collision with Eastern Avalonia. The development of the continuous Late Silurian foredeep basin along the EEC margin from the Peri-Tornquist Basin in the north-west to the present northern HCMts. implies that the North German-Polish Caledonides orogen had its NE continuation near the present Holy Cross area. The southern HCMts. comprise the northern margin of the Małopolska Massif (MM). The Ordovician-Silurian subsidence development of this area, its thermal history and crustal structure point to a stable cratonic setting. Existing similarities in sedimentary succession (mostly Ordovician and Lower Silurian) as well as clearly Baltic palaeobiogeographic affinities indicate a close spatial connection between the MM and Baltica during the analysed time interval. The juxtaposition of the MM against the ŁB area can be explained assuming that the MM is a part of Baltica detached from its margin due to right-lateral strike-slip after late Ludlow and before Emsian time.

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 regional subdivisions of major structural complexes distinguished in the Polish territory have been systematically corrected and updated parallel with accumulation of new geological and geophysical data. Regional units are established not only basing on their tectonic characteristics but also on other criteria including sedimentary and subsidence development, magmatism, metamorphism and crustal structure. In future, new units should be defined and older ones redefined in a possibly objective, descriptive way. However, the interpretative approach is unavoidable particularly when older, largely concealed structural complexes are concerned. Therefore, the establishment of formal criteria and "official"regional subdivisions analogous to formal stratigraphic units, seems inappropriate. Proposed schemes or modifications of previous subdivisions will serve as consistent and clear regional reference framework in geological and geophysical studies if they will meet few basic methodological and terminological requirements. Among the most important prerequisites is a clear definition of boundaries of particular units against most recent solid geological maps in a scale of 1:1 000 000 or larger. In accordance with the outlined guidelines the authors' version of the regional framework of Polish sub-Cenozoic and sub-Permian (Variscan) geological units is presented. The subdivisions are based on the modified scheme published by Dadlez (1998) and that by Narkiewicz (2007), respectively. We did not attempt to present a pre-Variscan (Caledonian) regional framework, except for the stable area of the East European Platform devoid of the Devonian-Carboniferous cover. Given the present state of research, such subdivision would be very speculative, reflecting only one of several possible interpretative variants of the Polish Lowlands deep structure.

Opis:
In June of 1843 Roderick Murchison visited Poland to overview local geology in order to fill the gap between the results of his Russian campaign (1840-1841) and the familiar geology of Western Europe. Recent examination of Murchison's hand-written "Journal" and field notebooks in the archive of the Geological Society of London allows a detailed reconstruction of his visit in the Polish territories. During the five-days "charge" across the Holy Cross Mountains the famous British geologist, accompanied by the outstanding Polish colleague Ludwik Zejszner, had collected plenty of observations that were later partly quoted in Murchison's monumental treatise about the geology of Russia (1845). Among the most important new findings is the identification of the Devonian sediments earlier included by Jerzy Bogumił Pusch (1833–1836) in the Formation of Übergangs Kalkstein und Breccie (Transitional Limestone and Breccia). Murchison’s visit and its results are echoed in later papers by domestic scientists, particularly those by Zejszner. The latter was the first Polish student of the Holy Cross Mountains geology who extensively introduced chronostratigraphic units established by Murchison, including the Silurian and Devonian in particular.

Opis:
Petrological studies of core samples, integrated with mesostructural analysis of cores, and coupled with results of seismic data interpretation allowed to interpret evolving reservoir properties of dolostones of the Frasnian Werbkowice Mb. These crystalline and partly vuggy rocks form main reservoir horizons of the Ciecierzyn and Mełgiew A gas fields in the central Lublin Graben. The optimum reservoir properties were attained following the main phase of regional dolomitization and accompanying CaCO3 dissolution. These processes occurred after renewed subsidence in Viséan and before main phase of the Variscan inversion in late Westphalian. In Late Silesian, after the onset of hydrocarbon generation, porosity was partly filled by a dolomite cement. The most important agent of porosity destruction, however, was a precipitation of anhydrite cement preceding main phase of compressional deformations. The latter led to a localized development of open fracture systems which, however, were soon filled with various cements related to dissolution-reprecipitation processes. After compressional event, the stress regime evolved towards strike-slip and extensional, which created fractures allowing migration of hydrocarbons to newly formed structural traps. Several observed structures indicate negligible post- inversion deformations, thus facilitating preservation of earlier formed hydrocarbon accumulations. However, successive stages of secondary migration could have occurred during indefinite time under strike-slip and extensional regime recorded as a distinct set of mesostructures.

Opis:
The results of GC-MS investigations of biomarkers in organic matter from the epicontinental Permian and Triassic strata of the Holy Cross Mts. indicate generally suboxic (Permian) and oxic (Triassic, except for the Middle Muschelkalk) depositional environments with accompanying intensive bacterial reworking of organic remains. The biomarker spectra found in the Middle Muschelkalk and in the Entolium discites Beds (Upper Muschelkalk) show the presence of gammacerane, an increased concentration of C34 homohopanes and a Pr/Ph ratio not exceeding 1. All these observations suggest a hypersaline sedimentary environment with water column stratification and poorly oxygenated conditions. Thermal maturity investigations were based on both vitrinite reflectance and biomarker indices. The organic matter in the Triassic succession is slightly more mature along the northern margin of the Holy Cross Mts. than along their southern part, due probably to a regional increase in the maximum burial depth during the Mesozoic. The maturity of the Permian strata at Gałęzice (southern Holy Cross Mts.) is similar to that of the Triassic rocks whereas Kajetanów (in the north) is characterised by values significantly higher and comparable to those found in wells further north. The difference cannot be accounted for solely by differential burial depths, and implies the existence of a positive thermal anomaly active before the Middle Triassic. Our investigations generally confirmed the low thermal maturity of the Triassic. However, contrary to earlier interpretations, we suggest that the maximum burial depths based on a reconstructed thickness of the post-Triassic deposits may account for the observed maturity levels, assuming that geothermal gradients in the Mesozoic were similar to today's.

Opis:
Paleomagnetic and petrological analyses were performed on Devonian carbonate rocks from the Kielce region (Janczyce 1 borehole, Dule, Łagowica escarpment, Budy Quarry) in the Holy Cross Mts. Rock samples were selected from localities with different degree of thermal alteration, diversified lithology and stratigraphy. Investigated carbonates, excluding those from the Budy Quarry, revealed traces of the Early Permian remagnetization related to magnetite. The intensity of the Late Variscan remagnetization is linked to rocks affected by the second stage of dolomitization with increased thermal maturity in the northern part of the Kielce region. The magnetic signal is probably related to rocks’self-cooling, fixed as a result of the latest Carboniferous to Early Permian uplift.

Opis:
The aim of the work was to determine the influence of weather conditions and a degree of weed infestation on the incidence of stem bases rot (Fusarium spp.) of winter wheat cultivars as well as their yield. The winter wheat cultivars (Kobra, Korweta, Mikon, Zyta) were investigated (2000-2002) in the field where the following herbicides: Apyros 75 WG + Atpolan, Affinity 50,75 WG, Attribut 70 WG were applied. It has been shown the occurrence of stem base rot (Fusarium spp.) depended mainly on weather conditions. The application of the herbicides improved the plant health. The stem base rot on winter wheat was caused by Fusarium spp., specially F. culmorum. The decrease in winter wheat yield depended on weather conditions, weed infestation and the occurrence of stem base rot (Fusarium spp.)
Celem pracy bylo określenie wpływu warunków pogody oraz stopnia zachwaszczenia łanu na występowanie fuzaryjnej zgorzeli podstawy źdźbła kilku odmian pszenicy ozimej oraz na ich plonowanie. Materiał badawczy stanowiły odmiany: Kobra, Korweta, Mikon i Zyta w latach 2000-2002. W czasie wegetacji roślin (faza krzewienia) stosowano Apyros 75 WG + Atpolan, Affinity 50,75 WG oraz Attribut 70 WG. Stwierdzono, że występowanie fuzaryjnej zgorzeli podstawy źdźbeł zależało głównie od warunków pogody. Odchwaszczenie herbicydami poprawiło zdecydowanie stan fitosanitarny roślin. Sprawcą zgorzeli podstawy źdźbła pszenicy ozimej były grzyby z rodzaju Fusarium a zwłaszcza gatunek F culmorum. Obniżenie plonów pszenicy ozimej zależało od warunków pogody, zachwaszczenia oraz od występowania fuzaryjnej zgorzeli podstawy źdźbła.

The model is composed of a fuselage, wings, an empennage, engine nacelles and rotors. Tiltrotor eąuations ofmotion were obtained by summing up inertia, gravity and aerodynamic loads acting on eachpart ofthe aircraft. Aerodynamic loads at wings, empennage and rotor blades are calculated using ąuasisteady model. For rotor induced velocity the Glauert model is used. The influence of rotor inflow wing and empennage aerodynamic loads is calculated using actual value ofinduced velocity. The computer program of tiltrotor model is developed in MatLab environment. The subprograms for load calculation are supplemented by modules for calculation of trim states and stability and control matrices.
Opracowano symulacyjny model statku powietrznego typu tiltrotor dla potrzeb analizy osiągów, stabilności i sterowania oraz symulacji lotu. Model wiropłata złożony jest z kadłuba, skrzydeł, usterzenia ogonowego, gondoli silnikowych i wirników. Równania ruchu zostały uzyskane z sumowania obciążeń bezwładności, grawitacyjnych i aerodynamicznych działających na każdy element statku powietrznego. Obciążenia aerodynamiczne skrzydeł, stateczników i łopat wirników zostały obliczone z zastosowaniem ąuasistacjonarnego modelu opływu. Do wyznaczania prędkości indukowanej wirników zastosowano model Glauerta. Wpływ na-czany z wykorzystaniem aktualnej wartości prędkości indukowanej. Program do modelowania wiropłata został opracowany w środowisku MatLab. Program złożony jest z modułów służących do obliczeń obciążeń poszczególnych elementów wiropłata, które wykorzystywane są również do wyznaczania warunków stanów ustalonych, stateczności i macierzy sterowania. Podczas pierwszego etapu badań wyznaczono warunki lotu ustalonego wiropłata typu tiltrotor w różnych konfiguracjach co pozwoliło zbadać zachowanie i potwierdzić poprawność modelu.
