摘要：This paper focuses on deformational structures seen at macro and mesoscales within the first Mid-Polish lignite seam (MPLS-1) currently exploited by the Konin Lignite Mine. In fact, the majority of examples presented herein come from the Jóźwin IIB and Tomisławice opencasts. The deformations are divided into two groups; they are tectonic and sedimentary ones. The first group includes deformations of the floor, faults, cleats, and seismically-induced structures such as breccia and deformed lamination. The second group covers compactionally-induced deformations of MPLS-1 roof, sedimentary breccia, and slumps. All these deformations are described and then briefly interpreted in this paper. Although in a few cases in the formation of sedimentary deformations, the contribution of the tectonic factor as a trigger mechanism seems obvious. This is supported by the fact that the mentioned lignite seam is mined in the areas of grabens that were tectonically active during the development of the Mid-Miocene mires in the Konin Basin.
