Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.

Limestone 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. Limestone vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Serpentinite. Learn more about Limestone vs Serpentinite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Limestone and Serpentinite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Limestone and Serpentinite
Here you can know more about Limestone and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Serpentinite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, 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 Limestone vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Limestone is Rough and Banded and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Limestone vs Serpentinite. The hardness of Limestone is 3-4 and that of Serpentinite is 3-5. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa 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 Limestone is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Limestone is 0.91 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.Limestone is pressure resistant whereas Serpentinite is heat resistant.
