    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. Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and en is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.. References. This geology article is a stub.

    (figs. 1 and 2). These deposits are mined primarily for their platinum, palladium, and rhodium contents (table 1). Magmatic ore deposits are derived from accumulations of crystals of metallic oxides, or immiscible sulfide, or oxide liquids that formed during the cooling and crystallization of magma, typically with mafic to ultramafic compositions.   Magmatic Nickel Deposits. A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson (Manitoba) (Figure ), and Voisey’s Bay (Labrador).Author: Steven Earle.

    Very importantly, the book shows clearly how the study of ore-forming processes helps in mineral exploration. I would advise all my graduate students to tackle this remarkable piece of work. Overall, Magmatic sulfide deposits is strongly recommended to professional economic geologists and any scientifically literate person who wants an Brand: Springer-Verlag Berlin Heidelberg.

Ore deposits are rarely comprised of % ore-bearing minerals, but are usually associated with rock-forming minerals during the mineralization process. These associated minerals or rocks, having no significant or low commercial value, are called gangue minerals.

Hydrothermal Fluids of Magmatic Origin In case of Degana and Tosham deposits, the excess vapour pressure of the fluid in the crystallizing granite caused the brecciation of the granite.

Magmatic sulfide ores are thought to form as the result of droplets of an immiscible sulfide-oxide liquid forming within silicate magma and then becoming concentrated in a particular location.

Certain elements, notably the Group VIII transition metals Fe, Co, Ni, Pd, Pt, Rh, Ru, Ir and Os together with Cu and Au, partition strongly into the. Mineral deposit - Mineral deposit - Magmatic cumulates: Magmatic segregation is a general term referring to any process by which one or more minerals become locally concentrated (segregated) during the cooling and crystallization of a magma.

Rocks formed as a result of magmatic segregation are called magmatic cumulates. While a magma may start as a homogeneous liquid, magmatic segregation. Abstract. A magmatic ore deposit is an accumulation of magmatic minerals.

Some of these minerals are extremely rare and almost never encountered in common rocks, an example being alloys of the platinum metals; other minerals, such as magnetite, are common and can be Author: Nicholas Arndt, Clément Ganino.

Porphyry copper (Mo-Au-Sn-W) deposits Porphyry ore deposits are products of magmatic-hydrothermal activity at shallow crustal levels.the arbitrarily defined lowest grade which will be mined from an ore ore deposit, and usually defines the boundary of the deposit.

For example, if the average grade of a porphyry deposit is % Cu, the cut-off might be % Cu. any rock with a grade below % Cu would be waste. Ore Deposits: Origin, Exploration, and Exploitation is a valuable resource for economic geologists, mineralogists, petrologists, geochemists, mining engineers, research professionals, and advanced students in relevant areas of academic study.
