Porphyry alteration
WebAug 23, 2024 · In our previous study on petrogenesis of quartz syenite and granite porphyry, the host rocks of the Late Mesozoic Shapinggou Mo deposit in the Qinling–Dabie orogenic belt, we found that the initial Sr isotopic composition of the host rocks is strongly affected by the degree of K-alteration. Here, we provide further isotopic evidence of the host rocks … 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.
