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
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Mudstone and Serpentinite Properties
Know all about Mudstone and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Mudstone is Clastic whereas that of Serpentinite is Earthy. Mudstone appears Rough and Dull and Serpentinite appears Rough and Dull. The luster of Mudstone is dull while that of Serpentinite is waxy and dull. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Serpentinite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Mudstone are creating artwork, pottery and that of Serpentinite are commemorative tablets, creating artwork.
