Archaeological Significance
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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

All about Turbidite and Chalk Properties
Know all about Turbidite and Chalk properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite and Chalk belong to Sedimentary Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Chalk is Clastic or Non-Clastic. Turbidite appears Dull and Banded and Chalk appears Soft. The luster of Turbidite is metallic while that of Chalk is dull. Turbidite is available in black, brown, green, grey, pink colors whereas Chalk is available in grey, white, yellow colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Chalk are alumina refineries, creating artwork, drawing on blackboards, gymnasts, athletes and mountain climbers use for grip, in aquifers, paper industry, production of lime, raw material for manufacture of quicklime, slaked lime, soil conditioner, whiting, whiting material in toothpaste, paint and paper.
