VERTICAL MINERAL ZONALITY OF THE SAN FERNANDO VOLCANOGENIC MASSIVE SULPHIDE DEPOSIT, CUBA

Volcanogenic 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...

Geophysical inversion in an integrated mineral exploration program: examples from the San Nicolás deposit

The ability to produce three-dimensional physical property models of the subsurface from surface geophysical data, coupled with an increasing need to explore for minerals in concealed terranes, results in geophysical inversions providing more significant information to the exploration team. We examine the role that geophysical inversion can play in an integrated mineral exploration program, and...

Generalized Ray Models of the San Fernando Earthquake

The exact Cagniard-de Hoop solut ions for a point dislocation in half-space are used to construct models of the strong ground motion observed during the February 9, 1971 San Fernando earthquake (PC, = 6.4). By summing point dislocations distr ibuted over the fault plane, three-dimensional models of a f inite fault located in a half-space are constructed to study the ground motions observed at J...

Mineral Deposit Studies

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...
