Definition

Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

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

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

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 Siltstone and Serpentinite Properties

Know all about Siltstone and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone belongs to Sedimentary Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Siltstone is Clastic whereas that of Serpentinite is Earthy. Siltstone appears Rough and Serpentinite appears Rough and Dull. The luster of Siltstone is dull while that of Serpentinite is waxy and dull. Siltstone is available in brown, red, reddish brown colors whereas Serpentinite is available in black, brown, green, grey, white colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner and that of Serpentinite are commemorative tablets, creating artwork.
