Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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 Claystone and Turbidite Properties
Know all about Claystone and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Claystone and Turbidite belong to Sedimentary Rocks.Texture of Claystone is Clastic whereas that of Turbidite is Mud-rich, Sandy. Claystone appears Rough and Dull and Turbidite appears Dull and Banded. The luster of Claystone is dull while that of Turbidite is metallic. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Claystone are pottery and that of Turbidite are cemetery markers, creating artwork.
