The Enrichment Mechanism of PGE and Characteristic of MSZ in HW Mining Area in Great Dyke Zimbabwe

Abstract:

Zimbabwe Great Dyke is a mafic-ultramafic lithosome intruded the Zimbabwe Craton. MSZ(Main Sulfide Zone) is the most important layer which contains substantial amount of PGE(Platinum Group Elements). PGE are concentrated in bottom of MSZ layer because of the intimate relationship between the content of Cu&Ni and enrichment of PGE. Acid vein rocks did not formed in the same period with the ore and adjacent rocks. Plenty of sulfide can be found in MSZ in pyroxenite, Sulfide in ore was owe to homogeneous of geochemistry process in the magamtic segregation cycle, while them in gabbro and fractures were simply by the post magmatic thermal solution activities.
