Magmatic sulfide deposits fall into two major groups when considered on the basis of the value of their contained metals, one group in which Ni, and, to a lesser extent, Cu, are the most valuable products and a second in which the PGE are the most important. Magmatic sulfide deposits can be subdivided into 1) Ni-Cu-PGE deposits, which have relatively smooth mantle-normalized metal patterns, 2) Ni-Cu-(PGE) deposits, which are depleted in PGE relative to Ni-Cu-Co, and 3) PGE-(Cu)-(Ni) deposits, which are enriched in PGE relative to Ni-Cu-Co.
China contains almost exclusively deposits in the second group, including the world’s Cited by: 3. magmatic Ni-Cu-PGE deposits. Tony’s students are involved in virtually every aspect of the Ni and PGE industries. He has served as mentor to many of the authors of the chapters con-tained in this book, and his willingness and desire to share his vast knowledge of magmatic ore deposits is a mark of the educator and the gentleman that Tony by: Most major magmatic Cu-Ni-PGE sulphide deposits are thought to have formed by segregation of an immiscible sulphide melt from a silicate host magma, in response to processes such as magma mixing, rapid cooling, differentiation, and by: Baumgartner RJ, Fiorentini M, Baratoux D, Micklethwaite S, Sener AK, Lorand JP et al.

This mineral phase exclusively contained crystal inclusions, of which quartz, biotite, plagioclase, and ilmenite occurred at highest frequency. These inclusions were mostly formed during feldspar crystallisation from the magmatic source.
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.

Magmatic Ni-Cu-PGE During the last three years, base-metal exploration in the region was mainly focused on the search for large, economically viable deposits of nickel, copper and platinum-group-elements associated with mafic and ultramafic rocks.
magmatic deposits - economic geology 1. magmatic deposits in reference to india 2. what are magmatic deposits. magmatic deposits are accumulations of magmatic minerals. they are characterised by their close relationships with intermediate or deep seated intrusive igneous rocks.
they constitute either the whole igneous mass or a part of it or may form offset bodies. they are magmatic. Layered, ultramafic to mafic intrusions are uncommon in the geologic record, but host magmatic ore deposits containing most of the world's economic concentrations of platinum-group elements (PGE) (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. Magmatic rock synonyms, Magmatic rock pronunciation, Magmatic rock translation, English dictionary definition of Magmatic rock.
The term for a rock formed when molten rock cools and hardens. Extrusive, or volcanic, igneous rock cools on the surface as lava. Magmatic Deposits deposits of minerals formed deep in the earth’s crust during the solidification and crystallization of basic or alkaline magma containing high concentrations of valuable minerals.
These deposits vary in shape and occur in igneous rocks that are related to them in origin. The formation of valuable minerals in magma that is cooling is. Magmatic Ni-Cu-PGE deposits are genetically more conventional, and until recently, their abundance has been modest. In the past 14 years, several significant base metal discoveries have been made in the poorly exposed McFaulds Lake greenstone belt in the Ring of Fire (ROF), situated within the Oxford-Stull domain of the North Caribou Superterrane.ISBN: X OCLC Number: Description: xxvi, pages: illustrations (chiefly color), color maps ; 25 cm: Contents: Machine generated contents note: PART 1 --ch.
