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.
Foidolites 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 Foidolite Properties
Know all about Turbidite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Foidolite belongs to Igneous Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Foidolite is Earthy. Turbidite appears Dull and Banded and Foidolite appears Dull. The luster of Turbidite is metallic while that of Foidolite is subvitreous to dull. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Foidolite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Foidolite are cemetery markers, commemorative tablets, creating artwork.
