Mugearite and Migmatite

Mugearite

Migmatite

Definition

Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides

Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Formation

Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
