The Fichtelgebirge is located on the border between Bavaria and the Czech Republic, the highest point being the Schneeberg (1051 m asl). The Naturpark Fichtelgebirge (Fichtelgebirge Nature Park) covers an area of 1020 km² on the German side. The Czech side of the Fichtelgebirge is called Smrčiny and is protected by Přirodní park Smrčiny (Fichtelgebirge Nature Park). It consists essentially of granite. Precambrian sediments were first folded during the Cambrian 570 Ma ago. In the Silurian, Devonian and Lower Carboniferous, deep-sea sediments were deposited, and deep-sea volcanism led to ore formation. The rocks were folded again by the Variscan orogeny in the Upper Carboniferous. This resulted in granite intrusions, which in turn led to the formation of hydrothermal ores.
