Formation

Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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 Minette and Turbidite Properties

Know all about Minette and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Minette belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Minette is Porphyritic whereas that of Turbidite is Mud-rich, Sandy. Minette appears Dull, Banded and Foilated and Turbidite appears Dull and Banded. The luster of Minette is subvitreous to dull while that of Turbidite is metallic. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Turbidite are cemetery markers, creating artwork.
