High sulfidation gold deposits
WebHigh-sulphidation deposits result from fluids (dominantly gases such as SO2, HF, HCl) channeled directly from a hot magma. The fluids interact with groundwater and form strong acids. These acids rot and dissolve the surrounding rock leaving only silica behind, often in a sponge-like formation known as vuggy silica. WebA similar transition between the high and intermediate sulfidation type mineralization, and the spatial association with a porphyry system is noted at many deposits including the …
