Archaeological Significance
Formation
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.
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Turbidite and Pyroxenite Properties
Know all about Turbidite and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Pyroxenite belongs to Igneous Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Turbidite appears Dull and Banded and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Turbidite is metallic while that of Pyroxenite is dull to vitreous to submetallic. Turbidite is available in black, brown, green, grey, pink colors whereas Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
