Quartz verins and associated high-temperature hydrothermal deposit intruded in in Miocene Tokuwa type of Kofu Granodiorite near the boundary with Sanpo Granodiorite. Quartz veins are intruded along a ring-shaped fissures. Quartz veins are 3 - 5 wide. The type locality of reinite, ferberite pseudomorph after scheelite.
Adit on a huge quartz vein in granodiorite. Side walls of this adit are white quartz. Wooden frames are in the adit. The cave at the right end of this photograph is a pocket.
