Abstract
The Shamva gold mine is hosted within the Shamva greenstone belt and is related to steeply dipping reverse-oblique crustal shear zones. Fluid infiltration resulted in widespread sulphidisation, K alteration, chloritisation, silicification and carbonatisation. Fluid inclusions from two types of quartz veins were used to estimate the composition and pressure-temperature conditions of gold mineralisation: (1) Au mineralised sulphie ± carbonate bearing veins; (2) late tensional barren veins. the vein types contain aqueous, mixed H
