5 Formation

5.1 Formation

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

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 Pyroxenite and Turbidite Properties

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