Geology and Geochemistry of Copper Mineralization of Volcanic Rocks Due to Quartz Veins in Western Part of Almus (TOKAT-TURKEY)

It is recognized that magmatic activities have occurred along the Izmir Erzincan suture due to closure of Tethyan ocean. In western part Almus (Tokat), which situated around this zone, quartz veins fracture lines are observed in volcanics owing magmatism. There copper enrichments with an average thickness 70 cm volcanic rocks. Mineralization as vein type and epigenetic formation. Paragenesis consists bornite, covellite, pyrite, magnetite ore forming phase goethite, malachite azurite supergeneous phase. geochemical analyzes, CuO value near surface reaches 23% presence azurites also 0.03% non-oxidized zones. This enrichment secondary Eocene rocks associated effect extension regime region.
