Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

All about Turbidite and Shale Properties
Know all about Turbidite and Shale properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite and Shale belong to Sedimentary Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Shale is Clastic, Splintery. Turbidite appears Dull and Banded and Shale appears Muddy. The luster of Turbidite is metallic while that of Shale is dull. Turbidite is available in black, brown, green, grey, pink colors whereas Shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Shale are creating artwork, pottery.
