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.
Picrite 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 Turbidite and Picrite Properties
Know all about Turbidite and Picrite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Picrite belongs to Igneous Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Picrite is Earthy, Rough. Turbidite appears Dull and Banded and Picrite appears Rough and Shiny. The luster of Turbidite is metallic while that of Picrite is subvitreous to dull. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo).
