PB - Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego N2 - It was proved that the main brown coal bed correlates with 2nd Lausic Seam in the Ścinawa Formation. This stratum has over 10 meter thickness. The uppermost coal layers have a little thickness and a small lateral extension. The lower coal seam belongs to the Rawicz Formation. It is not deformed. N2 - On the base of lithopetrographical researches sediments lying in glaciotectonical depression may be correlated with Elsterian glaciation. In Early Saalian glaciation (Odranian) a moving glacier leveled a morphological relief and caused accumulation of a glacial deposits on a glaciotectonical structure. In Late Saalian glaciation (Warthanian) the glacier reached south part the Muskau Arc and accumulated frontal moraines in Łęknica region. N2 - In the time of glacier pulling back the following arcs of recessional moraines remained: Bronowice-Nowe Czaple, Chwaliszów-Żarki Wielkie, Olszyna-Trzebiel. Muskau Arc is not a uniform thrust moraine but it is a very complicated structure. It consists of exterior arc located between Tuplice and Łęknica and internal located between Trzebiel and Siedlec, Tuplice-Chełmice-Jagłowice. N2 - They reflected a multiple formation of whole structure in the transgression of glacier. In the back side of the Muskau Arc between Olszyna and Jerischke the deep glaciotectonic depression occurred. The main coal seams correlated with 2nd Lausits Seam expose on the surface of thrust moraine. N2 - Extend of outcrops is compatible with run of geomorphological forms which reflect thrust shape of this structure. It is confirmed by boreholes and mining data. Apart from thrust structures there arc secondary folds and diapires in the strong plastic zones. N2 - There were created in the same dynamic process. The glaciotectonical model of cylindrical thrust by Rotnicki ( 1976) is accepted in this paper. In author's opinion glaciotectonical deformation were strengthened by mobile Mesozoic basement in the zone of crossing faults.
