Geology
Short characteristics of the site:
Moldanubicum of Šumava Mts. Active pit quarry. Important geological locality, showing rocks of the Varied Series of Moldanubicum. Several types of metamorphites are exposed, such as biotite paragneiss, crystalline limestone, metaquartzite, erlan, graphitic gneiss and amphibolite. These rocks are cut by thin veins of pegmatite with biotite. One of these pegmaitite veins was described as Li-pegmatite. In fissures, rare minerals of alpine paragenesis were found.
