GLACIOTECTONICALLY DEFORMED LIGNITE DEPOSITS IN THE AREA BETWEEN ŁAGÓWEK AND SIENIAWA, WESTERN POLAND
Journal Title: Civil and Environmental Engineering Reports - Year 2018, Vol 1, Issue 28
Abstract
The Sieniawa Lignite Mine, situated between Łagówek and Sieniawa in western Poland, has been operating for nearly 150 years. This territory was strongly affected by the Scandinavian ice sheets during the Pleistocene. The depth of these deformations reaches the main and currently exploited lignite seam of Miocene age, the second Lusatian lignite seam (LLS-2). Analysis of drilling profiles and observations of the lignite opencast walls allow documentation of the diversity and abundance of glaciotectonic deformation structures within Neogene and Quaternary sediments, which include upright and recumbent folds, normal and reversed faults, complementary joint sets, injection structures as well as shear surfaces.<br/><br/>
