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