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.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

All about Turbidite and Siltstone Properties
Know all about Turbidite and Siltstone properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite and Siltstone belong to Sedimentary Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Siltstone is Clastic. Turbidite appears Dull and Banded and Siltstone appears Rough. The luster of Turbidite is metallic while that of Siltstone is dull. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Siltstone is available in brown, red, reddish brown colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Siltstone are raw material for the manufacture of mortar, soil conditioner.
