Comparison of Mineral Deposits between Georgian and Turkish Sectors of the Tethyan Metallogenic Belt

摘要

Correlation between the Turkish and Georgian parts of the Tethyan Metallogenic Belt highlights the many similarities, particularly in the Cretaceous. VMS deposits are the most important deposit type and are largely of Kuroko-type in Turkey, although the stockwork type are predominant in Georgia, often with gold overprints. Eocene volcanics are host to vein precious metal deposits and become notably thick and alkaline immediately north of the Turkish Georgian border. Porphyry deposits appear to mainly associated with this event and contrast with the situation in Bulgaria. Other VMS deposits are associated with Jurassic volcanism and the eastern part of the area in Armenia has vein Au deposits and porphyries of Neogene age.
