Geology

Short characteristics of the site: Brno Massif, metamorphic mantle. Series of outcrops along the Vrbovec brook. Alternation oof siliceous gneisses and metamorphosed tuffs. They contain an interlayer of fine grained mylonitized amphibolites and lenses of tremolitic crystalline limestones. Rocks are gently folded and foliated. Crystalline limestones contain interesting association of minerals: Variable amount of dolomite, tremolite, chlorite, apatite and talk. Nearby diorite outcrops are separated by a fault line.
