Magmatic dispersion patterns typically involve decreasing concentrations of the ore minerals above or peripheral to the main deposit, reflecting incomplete separation of the ore minerals from the magma or other crystalline components. In some cases, the dispersion of ore minerals may be very localized.Mineral deposit | Britannica,Ore minerals tend to be concentrated in small, localized rock masses that form as a result of special geologic processes, and such local concentrations are called mineral deposits. Mineral deposits are what prospectors seek. The terms ore mineral and mineral deposit were originally applied only to minerals and deposits from which metals are recovered, but present usage includes a fewOre deposit | geology | Britannica,There are more than 25 known minerals containing mercury, but the principal ore mineral is cinnabar, a soft, red to reddish brown mercury sulfide. Some cinnabar deposits may also contain elemental mercury. The mineral has been found in all continents except Antarctica.Mineral Deposits Mineral Systems and Mineralising,Mineral deposits are therefore commonly clustered in geological provinces (mineral provinces or mineral districts) with some provinces being strongly endowed in particular mineral commodities (Jaireth and Huston, 2010).

The country is the world’s largest producer of chromium, nickel and palladium, has the largest proven reserves of iron ore, and is the second largest producer of aluminum, platinum and zirconium.Mineral Deposits: Types and Geology | SpringerLink,24/08/2017· Ore-forming processes (magmatic, sedimentary, hydrothermal, and metamorphic) are described before entering in the description of the main types of mineral deposits. Energy (petroleum, natural gas, tar sands, bituminous shales, coal, and uranium), metals (iron and steel, base metals, precious metals, light metals, and minor and specialty metals), and industrial minerals and rocksORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G,,ORE DEPOSIT TYPES Ore deposits can be classified on the basis of: - • Composition of the deposit (contained elements). • Form of the deposit (size, shape, orientation and ore mineral distribution). • Associated host rocks or geological structures (ore associations). • Interpreted genesis of the deposit (processes, controls).Geological ore deposits - The Australian Museum,The placer deposits usually form from primary deposits in which the ore mineral is widely disseminated and uneconomic. Concentration occurs when the surrounding rock is eroded away and the heavy ore mineral becomes concentrated by erosional processes. During transport of this material, concentration can occur within depressions, such as where a river changes its speed or in river bends,17 Major Mineral Resources Found in India,17 Major Mineral Resources Found in India.

An ore deposit, in its simplest terms, is a portion of the Earth’s crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical. Nevertheless, its formation required the operation of….
