Geology
Short characteristics of the site:
Moldanubicum, Raná Massif. Nature Reserve of the Protected Landscape Area. Anthropogenous relief with numerous flooded depressions after old limonite mining and adjacent vegetated spoil dumps. Bedrock consists of magmatites of the Raná Massif, mainly troctolites and peridotites. Sulphidic mineralization resulted in limonite accumulation. Mining works are as old as 600 years and culminated in the 18th century. The lakeletts are rimmed by small peat bogs.
