Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Enderbite and Appinite Properties
Know all about Enderbite and Appinite properties here. All properties of rocks are important as they define the type of rock and its application. Enderbite and Appinite belong to Igneous Rocks.Texture of Enderbite is Granular whereas that of Appinite is Porphyritic. Enderbite appears Veined or Pebbled and Appinite appears Dull, Banded and Foilated. The luster of Enderbite is while that of Appinite is subvitreous to dull. Enderbite is available in black, grey, orange, pink, white colors whereas Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Enderbite are curling, gemstone, laboratory bench tops, 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.
