Ore forming processes ~ Learning Geology

Hydrothermal vein deposits are formed when these hydrothermal solutions enter a country rock along cracks and fractures. It precipitates in the parent rock in a vein like structure. The hydrothermal solution in vein deposits can also soak through the country rock which for disseminated ore deposits.This is less concentrated but as formed with the vein together they form economical deposit.

Mineral deposit Hydrothermal solution Britannica

Mineral deposit Mineral deposit Hydrothermal solution: Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent. They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals.

Jul 16, 2015 · Hydrothermal deposits are diverse, being present in a wide range of geological settings and tectonic environments including intrusive or metamorphic terranes, subaerial and submarine volcanic provinces and sedimentary basins. What all the deposits have in common is their origin via the precipitation of metals or ore minerals from hot aqueous

Hydrothermal circulation Wikipedia

Hydrothermal circulation, in particular in the deep crust, is a primary cause of mineral deposit formation and a cornerstone of most theories on ore genesis. Hydrothermal ore deposits. During the early 1900s, various geologists worked to classify hydrothermal ore deposits that they assumed formed from upwardflowing aqueous solutions.

Hydrothermal deposits may also form subaerally in volcanically active areas. Hydrothermal mineralization is the precipitation of minerals out of the hot fluid.

Hydrothermal vent Wikipedia

A hydrothermal vent is a fissure on the seafloor from which geothermally heated water issues.
