Bobrowe Skały (Beavers Rock) GEOSITE

Title: Bobrowe Skały (Beavers Rock) GEOSITE
Description: The site represents a wide, latitudinal belt of orthogneisses belonging to the Jizera Metamorphic. It is located between the Szklarska Poręba shale belt in the south and the Kamienica shale belt in the north. The main core of Bobrowe Skały is built of porphyry granites, in which large "holes" form a microcline, and the fine-grained spaces between them are made of plagioclase, quartz, biotite and muscovite. These granites occur among occluded-layered gneisses. The gradual transitions between these rocks are the result of tectonic deformation taking place at temperatures of about 300 degrees Celsius at depths of up to 5 km, which took place in the Lower Carboniferous (350–330 million years ago), i.e. during the Variscan movement
