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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Turbidite and Metapelite Properties
Know all about Turbidite and Metapelite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite belongs to Sedimentary Rocks while Metapelite belongs to Metamorphic Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Metapelite is Foliated. Turbidite appears Dull and Banded and Metapelite appears Banded. The luster of Turbidite is metallic while that of Metapelite is earthy. Turbidite is available in black, brown, green, grey, pink colors whereas Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Metapelite are commemorative tablets, creating artwork.
