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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Turbidite and Pumice Properties
Know all about Turbidite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Pumice belongs to Igneous Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Pumice is Vesicular. Turbidite appears Dull and Banded and Pumice appears Vesicular. The luster of Turbidite is metallic while that of Pumice is earthy. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums.
