| Description | The main concern of this study is the tectonics of the Macocha Abyss (Macocha Chasm) and a part of the Punkva Cave in the Moravian Karst. Two systems of subvertical faults with NNE–SSW and NW–SE strike are the most important for the genesis of the abyss. Th e third system (related to décollements) strikes NE–SW and dips 40 to 60 degrees to the SE. The intersection of these three systems was crucial for the collapse of the roof of the original cave dome and the genesis of the abyss. Th ese structures were formed during the Variscan orogeny but modifi ed during the Alpine orogeny. A 3D model of the Macocha Abyss based on a geodetic surveying is presented. |
