Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Etymology
From English clay and stone as the rock contains more amount of clay
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

Features
Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Claystone and Dolomite Properties
Know all about Claystone and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Claystone and Dolomite belong to Sedimentary Rocks.Texture of Claystone is Clastic whereas that of Dolomite is Earthy. Claystone appears Rough and Dull and Dolomite appears Glassy or Pearly. The luster of Claystone is dull while that of Dolomite is vitreous and pearly. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Dolomite is available in black, brown, green, grey, pink, white colors. The commercial uses of Claystone are pottery and that 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).
