Abstract
The study area is located in the Çorum province, in the Central-Inner Black Sea region, North-Central part of Turkey. In the Çorum region various continental blocks are found together. Devecidağ Complex, Artova Ophiolite Complex, Alacahöyük, Bayat, Kızılırmak, Dodurga and Bozkır formations and Dededağ granitoid and quartz veins are exposed in the vicinity of the study area. Extremely altered volcanic rocks, andesite-basalt-trachyte and tuffs are observed near the mineralisation. The silica veins associated with the mineralisation crop out in NE-SW direction southeast of Şaphane village. Pyrite, hematite, limonite and gold are the major ore minerals within the quartz veins.
 In the fluid inclusion studies, it was determined that hydrothermal solutions contain several salts such as NaCl, CaCl2 and MgCl2, the salinity values (wt.% NaCl) changed between 8% and 0.5% in quartz, from 7.4 and 1.4% in calcite, and the temperature of the solutions varied between 161 and 395°C. Available data indicate that the mineralisation in the region is associated with quartz veins and formed under epithermal-mesothermal conditions.
