The Bahcecik prospect is a low sulphidation epithermal mineralised system, located ~40 km SE of Trabazon, in the eastern Pontide tectonic province of the north eastern Black Sea region of Turkey.
Gold mineralization occurs in Late Cretaceous to early Tertiary volcanic rocks, localized along east-trending normal faults and lithologic contacts.
An early quartz-sericite alteration event was focused along the major fault in the area and resulted in precipitation of arsenian (?) pyrite with anomalous gold. This was overprinted by a later, more spatially extensive, advanced argillic alteration event.
Native gold occurs as disseminations and fracture fillings in quartz. Gold mineralization is restricted to the high-temperature portion of the alteration zone characterized by quartz veins with diaspore-pyrophyllite selvages. The prospect area has been subjected to Tertiary to Holocene supergene alteration.
The most recent source geological information used to prepare this decription was dated: 2000.
