Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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

Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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

All about Granulite and Appinite Properties

Know all about Granulite and Appinite properties here. All properties of rocks are important as they define the type of rock and its application. Granulite belongs to Metamorphic Rocks while Appinite belongs to Igneous Rocks.Texture of Granulite is Granoblastic whereas that of Appinite is Porphyritic. Granulite appears Veined or Pebbled and Appinite appears Dull, Banded and Foilated. The luster of Granulite is vitreous while that of Appinite is subvitreous to dull. Granulite is available in black, brown colors whereas Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones and that of Appinite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner.
