Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Features
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

All about Dolomite and Flint Properties
Know all about Dolomite and Flint properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Flint belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Flint is Banded, Rough. Dolomite appears Glassy or Pearly and Flint appears Glassy or Pearly. The luster of Dolomite is vitreous and pearly while that of Flint is vitreous. Dolomite is available in black, brown, green, grey, pink, white colors whereas Flint is available in black, brown, green, grey, red, 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 Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
