Structures of Mineral Deposits - geologyin.com

Mineral deposits formed as a consequence of sedimentary processes. Structural deformation may alter the form and attitude of some of these deposits. Lenticular masses, veins, lodes and zones of disseminated mineralization result from metamorphic processes. Recognition of the environment and existence of potentially economic mineral deposits may be based upon a variety of geological criteria:

6 Metamorphic Rocks – An Introduction to Geology

6.4 Metamorphic Environments. As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. The names of metamorphic facies on the pressure-temperature diagram …

chapter, and in the formation of mineral deposits. Time Most metamorphic reactions take place at very slow rates. For example, the growth of new minerals within a rock during metamorphism has been estimated to be about 1 mm per million years. For this reason, it is very difficult to study metamorphic processes in a lab.

Hydrothermal mineral deposit - Wikipedia

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 minerals.In some occurrences, minerals can be extracted at a profit by mining.
