Definition

Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

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

Formation

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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.
