Archaeological Significance
Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Peridotite and Latite Properties
Know all about Peridotite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite and Latite belong to Igneous Rocks.Texture of Peridotite is Phaneritic whereas that of Latite is Aphanitic to Porphyritic. Peridotite appears Rough and Shiny and Latite appears Rough. The luster of Peridotite is shiny while that of Latite is subvitreous to dull. Peridotite is available in dark greenish - grey colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
