Metallic Deposits CliffsNotes

Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined.Again, the profit line

20.1 Metal Deposits Physical Geology

Sep 01, 2015· There is a very wide variety of ore-forming processes, and there are hundreds of types of mineral deposits. The origins of a few of them are described below. 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.

ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G

PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore.

Metallic Ore Deposits Associated With Mafic to Ultramafic

Jan 01, 2018· Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with

Types of Minerals Definition, Classification & Examples

Volcanic rocks contain bauxite deposits in some regions. Iron metal extracted from iron ore. It never exists in pure form and has to be extracted from iron ore by eliminating the impurities. Gold is the oldest and most precious element to be known. Manganese ore is a silvery brittle or grey-white metallic ore occurs in many forms and found

Ore Deposit an overview ScienceDirect Topics

Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite

Ore Deposits and Plate Tectonics Angelfire

Ore Deposits and Plate Tectonics. Plate tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits.The relationship of plate tectonics and mineral deposits is significant on three counts: Geological processes operating due to energy released at plate boundaries control the process of mineral deposition.
