Zusammenfassung: | On the background of a critical review of earlier studies and concepts concerning the structure of the pre-Permian basement of LGOM, the authors’s own, modified version of its tectonic model is presented, accompanied by that explaining the sedimentation and areal extent of the Lower Permian sedimentary cover. Integrated sedimentological, structural and tectonic analysis was applied in conjunction with geophysical analysis based on gravimetric and magnetic data. As a result of the analysis, the pre-Permian basement of the LGOM area is interpreted to be part of the northern Variscan internides and, at the same time, to constitutea northerly extension of the Fore-Sudetic block (Sieroszowice block) . Within the LGOM area, in its southern part, there are middle Odra fault zone, comprising the southern middle Odra fault (Lubin trough) and northern middle Odra fault, separated with the Sieroszowice block. In the middle part of the LGOM area located is the Głogów trough, cut by the Silesia-Lubusz fault in its northern segment and by the southern part of the vast middle Odra deep fracture zone. |
