Mineral deposit types are groups of mineral deposits having similar geologic characteristics, geologic environments of occurrence, and geologic processes of formation Guilbert and Park, 1986 Cox and Singer, 1986 Bliss, 1992. There are different mineral deposits depending on their formation style.

Magmatic Ore Deposits Chapter 2 Ore Deposit Geology

Magmatic ore deposits, also known as orthomagmatic ore deposits, are deposits within igneous rocks or along their contacts in which ore minerals crystallised from a melt or were transported in a melt. Ore deposits that form in and around igneous rock units as a result of mineral precipitation from aqueous solutions or hydrothermal fluids are hydrothermal ore deposits.

A hot, fluid residue, usually of magmatic origin, that is chiefly water contains a rich supply of metallic elements. It becomes further enriched through chemical reactions with the surrounding crustal rock. As it cools, this solution many form massive concentrations of minerals bearing gold, copper, and zinc and other metallic elements that may have great commercial value. Some of the worlds richest deposits of these metals were formed under such hydrothermal conditions.

And the epithermal mineral assemblage is developed under the relatively coolest, and, therefore, shallowest, portions of Earths crust. In the series of three cases that you see here, all the minerals were developed under the hydrothermal environment.

Porphyry coppers are often associated with stratovolcanoes. As a result of the volcanism that rings the Pacific Ocean basin, porphyry coppers are conspicuous features of mineralization along the western borders of North and South America and in the Philippines. Among the major deposits are El Teniente, El Salvador, and Chuquicamata in Chile, Cananea in Mexico, and, in the United States, Bingham Canyon in Utah, Ely and Yerington in Nevada, and San Manuel in Arizona.

The mining of magnetite from a skarn deposit at Cornwall, Pennsylvania, U.S., commenced in 1737 and continued for two and a half centuries. Copper skarns are found at many places, including Copper Canyon in Nevada and Mines Gasp in Quebec, Canada. Tungsten skarns supply much of the worlds tungsten from deposits such as those at Sangdong, Korea King Island, Tasmania, Australia and Pine Creek, California, U.S.

Mineral deposit types at a variety of scales. The volume starts with two scene-setting chapters. First, Tom Blenkinsop, Nick Oliver, Paul Dirks, Michael Nugus, Gerard Tripp, and Ioan Sanislav demonstrate how principles of structural geology can be applied to understanding hydrothermal gold deposits using predominantly lode gold case studies.

As we know, an ore is composed of ore minerals and gangue, which can be utilised for a profitable extraction of one or mere metallic compounds or metals. The entire crust of the earth consists of minerals. They occur as solid masses, or rocks of which the earth8217s crust is composed, or as local accumulator s of varying size, such as veins, pockets or impregnations in rocks.

The magmatic deposits are classified into two major groups, viz., i Early magmatic deposit, and ii Late magmatic deposit. The early magmatic deposits are believed to have been formed simultaneously with the host-rock, whereas the late magmatic deposits are formed towards the close of the magmatic deposits.
