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.

Siltstone vs Serpentinite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Siltstone vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Siltstone and Properties of Serpentinite. Learn more about Siltstone vs Serpentinite in the next section. The interior uses of Siltstone include Decorative aggregates and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Siltstone and Serpentinite, they have various applications in construction industry. The uses of Siltstone in construction industry include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Siltstone and Serpentinite
Here you can know more about Siltstone and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Serpentinite consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Siltstone is Rough and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Siltstone vs Serpentinite. The hardness of Siltstone is 6-7 and that of Serpentinite is 3-5. The types of Siltstone are Siltstone whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Siltstone is 0.84 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Serpentinite is heat resistant.
