Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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