Skałka Teściowej (Mother In-Law's Rock) GEOSITE

Title: Skałka Teściowej (Mother In-Law's Rock) GEOSITE
Description: The Mother-in-law's Rock is composed of typical hornfels belonging to the granite cover of the Karkonosze pluton. They were created as a result of the impact of granites on the slates of the Szklarska Poręba range. Contact with the granites runs approximately 400 m to the south. These are gray and dark gray rocks with a characteristic lumpy structure and clearly visible orientation of minerals. The mineral composition includes quartz, biotite, chlorite and typical contact minerals: cordierite and andalusite, which intertwine with quartz to form characteristic lumps on the rock surface.
