Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Archaeological Significance
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Appinite and Serpentinite Properties
Know all about Appinite and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Appinite belongs to Igneous Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Appinite is Porphyritic whereas that of Serpentinite is Earthy. Appinite appears Dull, Banded and Foilated and Serpentinite appears Rough and Dull. The luster of Appinite is subvitreous to dull while that of Serpentinite is waxy and dull. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Serpentinite is available in black, brown, green, grey, white colors. The commercial uses of Appinite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner and that of Serpentinite are commemorative tablets, creating artwork.
