Appinite and Blue Granite

Appinite

Blue Granite

Definition

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

Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar

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.

Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.
