Large-scale fluid flow in basins are described using MVT deposits with source of sulfides for ore deposition, fluid flow paths along.

    focus on secular trends of carbonate-hosted Zn-Pb deposits, including MVT and CD Zn-Pb deposits, emphasizing that both deposit types are inextricably linked to the opening and closing of ocean basins and the oxygenation of the hydro-sphere. Summaries of shale-hosted deposits in the northern hemisphere by Goodfellow and Peter and those in the south-. and Clastic dominated (CD) ores appeared in the rock record after the GOE. CD Zn-Pb-Ag deposits became abundant about Ga when oxidizing gypsum-bearing evaporites became important. Mississippi Valley-Type ores in the Proterozoic were mostly limited to small evaporite “oasis” and did not become abundant until after the second.

The ore deposit ( Mt of 17% Zn+Pb) was formed in two main stages, possibly by two different fluids. The first stage was Zn>Pb and had δ 34 S-H 2 S of 18±6‰ (VCDT), whereas the second stage. Volcanic-hosted, massive sulfide deposits of Zn-Pb-Cu type were derived either from seawater-dominated, buoyant fluids that built mounds on the seafloor, e.g., the ores of the Hokuroku Basin, Japan, or from saline fluids that reversed buoyancy on mixing with seawater and filled basins on the seafloor, e.g., several ores of the Iberian pyrite belt and the Mount Read province in by: Zn-Pb-Ag mineral deposits are the products of hydrothermal ore-forming systems, which are restricted in time and space.

The ores are of typical open-space filling and replacement. In general, the 3-dimensional shape of the whole orebody is mushroom-like, with an ore-bearing sandstone cap and ore-bearing breccia root (Xiu et al., ), dominated by Zn–Pb ores with variable Zn/Pb ratios from to (Xue et al., ).Cited by: hot mineralizing fluids in shale-dominated basins.

In these models the fluids could be rapidly injected from depth, thus conserving their heat. should be noted that compaction-driven fluid migration was a mech­ anism already proposed by different authors in the s and s.

Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin.

These ore bodies range from million tonnes of contained ore, to 20 million tonnes or more, and have a grade of between 4% combined lead and zinc to over 14% combined.

The epigenetic Zn-Pb deposits in the Lycksele-Storuman ore district, northern Sweden, are hosted by Paleoproterozoic basement near the margin of the Caledonian mountains.

A paleogeographic reconstruction suggests that platform sediments, including Cambrian shales, overlaid the mineralised basement. The mineralisation type, containing sphalerite, galena, calcite and fluorite, is confined to Cited by: 7.

Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore some occurrences, minerals can be extracted at a profit by hermal: Ore minerals are precipitated by a hydrothermal solution percolating through intergranular spaces and along bedding planes and fractures in the host rocks.

Germanium (Ge) is considered a critical element due to its many industrial applications; Ge is a metalloid used in solar cells, fiber optics, metallurgy, chemotherapy, and polymerization catalysis.
