Magmatic differentiation accounts for a variety of igneous rocks occurring in the same body of rock by:
- Mixing of magmas from two or more sources.
- Distinct melting events from a variety of sources.
- Crystal fractionation
- Partial melting from the same source.
- Immiscibility.
- Assimilation of crustal rock by magma.

What types of accounts are offered by TD Canada Trust?

How does fractional crystallization lead to magmatic differentiation?
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
