and accounts for over 60% of total gold production in Ghana. Two types of gold mineralization are identified in the Birimian: a quartz-vein type with gold occurring as native gold, and as disseminated gold in sulphide ore, where the gold occurs as submicroscopic grains in the sulphide ores. Gold

Fluid inclusions were studied in samples from the Ashanti, Konongo-Southern Cross, Prestea, Abosso/Damang and Ayanfuri gold deposits in the Ashanti Belt, Ghana. Primary fluid inclusions in quartz from mineralised veins of the Ashanti, Prestea, Konongo-Southern Cross, and Abosso/Damang deposits contain almost exclusively volatile species. The …
