magmatic segregation mineral deposits

Magmatic segregation geology Britannica

formation of mineral deposits. 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.

Magmatic Segregation Mineral Deposits

Magmatic Segregation Mineral Deposits. 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 Segregation - Mining Fundamentals

Some of the commonly formed mineral deposits formed due to magmatic segregation are iron, granite, aluminum, diamond, chromite, and platinum. The different temperatures and basicity zones that prevail in magma cause the concentration of the ore, thereby resulting in the segregation of various minerals.

Magmatic hydrothermal deposits SpringerLink

In this chapter we turn our attention to other magmatic activity which results in important mineral deposits. These are not ores that have segregated during crystallization of the magma but are those that arise by hydrothermal activity associated with igneous bodies emplaced at high levels in the earth’s crust.

Ore deposits related to magmatic activity

Late Magmatic Deposits: Those which consist of minerals crystallizing from a magma towards the close of magmatic period. The ore minerals are later than the rock silicates and cut across them, embay them, and yield reaction rims around earlier minerals. They are always associated with mafic igneous rocks.

Primary Magmatic Segregation Deposits in New

Mineral deposits in New Zealand whose origin can be ascribed to primary magmatic segregations are associated with mafic-ultramafic complexes related to two orogenic episodes which took place during Palaeozoic and Mesozoic times. These mafic-ultramafic complexes are essentially of two types.

Process of formation of mineral Deposits % -

The magmatic segregation and formation of pegmatites leaves the residual magma very fluid and it contains gases of great chemical activity. These gases penetrate the adjacent country rock and by their reaction with the latter form mineral deposits Such deposits are known as pneumatolydc ore deposits. Examples are cassiterite deposits.

2005-3-1  Thus, dynamic sulfide-forming magmatic systems may be intrinsically self destructive, but this apparently undesirable attribute could play an important role in forming high-grade deposits. However, dissolution could lead to the complete destruction of sulfide liquids and the return of all metals to later magma batches.
