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