Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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 Dolomite and Turbidite Properties
Know all about Dolomite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Turbidite belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Turbidite is Mud-rich, Sandy. Dolomite appears Glassy or Pearly and Turbidite appears Dull and Banded. The luster of Dolomite is vitreous and pearly while that of Turbidite is metallic. Dolomite and Turbidite are available in black, brown, green, grey, pink, white colors. The commercial uses of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Turbidite are cemetery markers, creating artwork.
