igneous differentiation

Differentiated - a meteorite that has undergone igneous differentiation.

Restite is an important constituent in fractional crystallisation and igneous differentiation processes.

They most likely formed from the breakup of a basalt object, which in turn was spawned from a larger parent body that underwent igneous differentiation.

(See igneous differentiation and fractional crystallization.)

Magmas will evolve to the eutectic because of igneous differentiation, or because they represent low degrees of partial melting.

A parental melt is a magma composition from which the observed range of magma chemistries has been derived by the processes of igneous differentiation.

The Shonkin Sag laccolith is cited by geologists as a classic example of igneous differentiation in a single igneous intrusion.

Igneous petrology: the study of igneous processes such as igneous differentiation, fractional crystallization, intrusive and volcanological phenomena .

These results also suggest significant depletion of the early Archean mantle, in agreement with the early igneous differentiation of the Earth that the latest core formation models require.

In geology, igneous differentiation is an umbrella term for the various processes by which magmas undergo bulk chemical change during the partial melting process, cooling, emplacement or eruption.

Because most Ni behaves as a compatible element in igneous differentiation processes, the formation of nickel-bearing sulfides is essentially restricted to sulfide saturated mafic and ultramafic melts.

This is, of course, an artificial set of constraints, and means that the results of the CIPW norm do not reflect the true course of igneous differentiation in nature.
