Magmatic Differentiation

The process of separation of different mineral constituents from magmatic melt is called magmatic differentiation.

Types of magmatic differentiation
Magmatic differentiation is of following types:
1Gravitational differentiation: In this process earlier formed minerals get precipitated.By this minerals are disintegrated.
2Difeerentiation due to fractional differentiation:In crystallization different centers of molecules are formed.This centers attract other molecules causing separation of of magmatic materials.
3Differentiation due to liquid immiscibility:In liquid magma there are many immiscimle particles.These when cools becomes disintegrated.
4.Differentiation due to filter pressure:Earlier formed particles when get cooled they are squeezed due to compression.As a result liquid particles get out causing disintegration of minerals.(Sometimes when liquid mud get hard some crack like holes form.This is also formed when earlier mud mud particles get cooled they are squeezed due to compression.)
