Ptáček, Jiří ; Grygar, R. ; Koníček, Petr ; Souček, Kamil ; Staš, Lubomír ; Waclawik, P.
A stresss strain model of Variscan structural tectonic pattern in the Czech part of Upper Silesian Coal Basin (USCB) based on paleostress analyse have been interpreted. It was compiled used many of tectonic measurements of planar and linear elements and their comparison with the knowledge of dynamic development of Variscan body in a larger framework of Moravo Silesian zone. It was took account the influence of Alpine deformation due to Carpathian nappe. There were more stress tensor gauging realised in the region above all using hydrofrac and treated overcoring methods during last ten years. It’s becoming apparent that for information of recent stress fields is usable the interpretation of focus mechanisms of energetic significant seismic events, which were observed here more than ten years. The aim of project is the verification of recent stress strain state in the easternmost region of Czech part of USCB.
