WebApr 1, 2024 · Our understanding of the origin of hydrothermal propylitic alteration assemblages in intrusion-centred magmatic-hydrothermal systems has changed little since the first geochemical and isotopic studies in the late 1970s and 1980s. Recently, the propylitic alteration haloes around porphyry-copper ore deposits have received increasing … WebThe most intense stockwork veining and alteration, and the highest Au and Cu grades occur immediately adjacent to the monzonite porphyry. The best part of the orebody occurs above the porphyry and the weaker parts along the sides. The intensity of veining and alteration declines both outwards and inwards from the monzonite porphyry margin. billy w moore
