Investigation of blind massive sulphide deposit signatures in the calcrete layers as a geochemical barrier: A case study of Areachap, Kantienpan and Copperton deposits
The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated in non-magnetic and magnetic part of calcrete. Based on the current research, mineralogica...
متن کاملVolcanogenic Massive Sulphide Deposits
Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and volcano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic environments. They form from metal-enriched fluids associated with seafloor hydrothermal convection. Their immediate h...
متن کاملGeochemical and mineralogical characteristic of the VHMS alteration pipe, major elements variations and peraluminous ratio, in high grade metamorphosed rocks
The massive sulphide deposit at Kantienpan Cu-Zn mine is hosted by volcano sedimentary succession known as the Areachap Group, in the eastern part of Namaqua Metamorphic Province, South Africa. The deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted m...
متن کاملmineralogical and geochemical characteristics of the amensif cu, pb, zn, (ag, au) ore deposit, western high atlas, morocco
the cu, pb, zn, ag-au deposit of amensif is located on the northern flank of the western high atlas. this deposit is hosted in lower cambrian carbonate bars and is structurally controlled by ne-sw to e-w trending fault structures and is spatially associated with the permian 273 ma azegour granite. ore reserves are around 0.5 mt and grades are 3.21% zn, 0.58% pb, 0.86% cu with 83.31 ppm ag and 0...
متن کاملMineralogical and Geochemical characteristics of the Chah-Shur Clay Deposit, Southeast of Isfahan, Iran
The Chah-Shur clay deposit is located in150 km southeast of Isfahan. Eocene igneous rocks and Quaternary deposits cover the area. Eocene volcanic rocks include andesite and tuffs which relating to magmatic activities of Urumieh-Dokhtar magmatic belt. Alteration of the vitric and lithic tuff units has produced the clay deposit. Based on the petrographic studies, the main minerals in tuff uni...
