Wydział Geologii, Geofizyki i Ochrony Środowiska
Celem niniejszej pracy dyplomowej było dokonanie interpretacji jakościowej profilowań geofizyki otworowej dla utworów permskich. Dane otworowe pochodziły z rejonu bloku Gorzowa na Niżu Polskim. Pierwszą częścią prac była analiza profilowań pomiarowych. Opisano charakterystyki krzywych geofizycznych dla różnych typów litologicznych. Druga część obejmuje analizę parametrów gęstości objętościowej i prędkości fali podłużnej dla dolomitu głównego (Ca2), starszej soli kamiennej (Na2) oraz anhydrytu głównego (A3). Ponadto porównano średnie wartości tych parametrów z poziomów węglanowych i ewaporatowych z tabelarycznymi parametrami petrofizycznymi. Opracowanie to pozwoliło wnioskować o potencjale zastosowania interpretacji jakościowej pomiarów geofizyki otworowej w ocenie litologicznej utworów permu.

Permian to Triassic paleokarst of the Świętokrzyskie (Holy Cross) Mts, central Poland
(Wydawnictwa AGH, 2007) Urban, Jan
This paper presents classification of the Permian and Triassic paleokarst forms in the Świętokrzyskie Mts, systematic description of the groups of forms and their fillings as well as conclusions concerning environmental conditions of their development. Four groups were distinguished among paleokarst forms developed before the deposition of the Buntsandstein whereas five ones developed during the Buntsandstein deposition (proceeding diachronically) and/or the Middle Triassic time. The Permian-Triassic paleokarst was conditioned by the Variscan tectonic movements and up-lift as well as subsequent formation of the Danish-Polish Trough. The Permian karst developed in the area of mountainous morphology and were often connected with hydrothermal processes. The Triassic karst formed due to tectonic activity stimulating morphological rejuvenation of the region. Wide and low passages representing one of the Triassic paleokarst group presumably formed in fresh and sea waters mixing zone.

Phanerozoic paleoenvironment and paleolithofacies maps. Late Palezoic
(Wydawnictwa AGH, 2007) Golonka, Jan
The paper presents the detailed plate tectonic, paleogeographic, paleoenvironment and paleolithofacies maps for eight Late Paleozoic time intervals. These maps are dealing with the Devonian, Carboniferous and Permian time slices. The relationship of the continental configuration, lithofacies, tectonics and climate from the disassembly of Oldredia to the assembly of Pangea is clearly depicted on this series of reconstructions. The distribution of lithofacies shows climatic change associated with continental disassembly and assembly. The breakup of continents and origin of oceans generated basins related to rifting and passive margin development. The assembly of continents contributed to the formation of foreland basins. The subduction zones are related to the back--arc basins. The biological extinction events were perhaps related to the plate reorganization and mantle plume activity.

Występowanie i geneza siarkowodoru w utworach permu kopalni Rudna

Recently in Polish cuprum mines belonging to KGHM Polska Miedź S.A. began to observe presence of hydrogen sulphide in mine air, especially during recognition and exploitation works. Since it is very toxic gas it is crucial for the safety of miners to localize the zones where its accumulations occur. Presence of hydrogen sulphide can be the product of three geochemical processes occurring in geological environment: bacterial sulphide reduction (BSR), thermochemical sulphide reduction (TSR), and thermochemical decomposition of organic sulphur contained in kerogen or crude oil. The following study focuses only on the first two of them. Since they occur in two different thermal regimes their products are also different. One way to explain the origin of hydrogen sulphide is to compare isotopic composition of the products of sulphate reduction with composition of original rock from which they derived. The following study presents the results of stable carbon and oxygen isotope 3 composition of secondary carbonates in comparison with isotopic composition of these elements in dolomites. On the basis of gathered data it is not possible to unambiguously determine the process responsible for hydrogen sulphide formation.
