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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Peridotite and Turbidite Properties
Know all about Peridotite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Turbidite is Mud-rich, Sandy. Peridotite appears Rough and Shiny and Turbidite appears Dull and Banded. The luster of Peridotite is shiny while that of Turbidite is metallic. Peridotite is available in dark greenish - grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Turbidite are cemetery markers, creating artwork.
