Definition

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

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation

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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Mudstone and Limestone Properties

Know all about Mudstone and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone and Limestone belong to Sedimentary Rocks.Texture of Mudstone is Clastic whereas that of Limestone is Clastic or Non-Clastic. Mudstone appears Rough and Dull and Limestone appears Rough and Banded. The luster of Mudstone is dull while that of Limestone is dull to pearly. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Mudstone are creating artwork, pottery and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
