Geology

Short characteristics of the site: Barrandian Neoproterozoic and magmatites. Active quarry where "Tisá granite" is being exploited.

Interesting enclosure of Proterozoic schists are present as well as veins of hydrothermal quartz. In some parts phenocrysts of potassium feldspar are present. Broad spectrum of accessoric minerals, also with fluorite and monazite.
