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

2021-6-10  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.

Mineral Ore Deposits: Meaning, Origin and Types

2021-6-13  Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit. These are sometimes classified as a distinct group of magmatic deposits formed towards the end of crystallization process and as such necessarily occurring close to the roofs of magmatic masses. The process of metasomatic replacement may be

2012-2-7  (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. “PGE reefs” are stratabound PGE-enriched lode mineralization in mafic to ultramafic layered

2017-6-26  A syngenetic mineral deposit is a deposit which formed at the same time as the rocks that enclose it. Magmatic deposits are syngenetic in that the ore minerals crystallize from the same liquid that produces the silicate minerals which form the bulk of the intrusive they crystallize more or less simultaneously as the melt cools.

Processes that Concentrate Mineral Resources

2018-3-13  Processes that Concentrate Mineral Resources. A number of processes occur in igneous rocks to provide accumulations of otherwise rare elements or minerals. Most minerals are made up of the eight abundant elements, and most surface minerals are silicates.Our capacity to find the "needle in the haystack" of the metals such as gold, silver, etc. comes from the fact that there are igneous
