Geology
Short characteristics of the site:
Acif felsic metavolcanic roks (porphyroid embedded within chlorite-sericite phyllite (bottom) and graphite-sericite phyllite (top). Relics porphyritic texture and fine grained matrix shows its volcanic (lava) origin. Chemistry of rocks proves the orignin by melting of continental crust during Cambro-Ordovician rifting.
