Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Peridotite vs Limestone 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. Peridotite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Limestone. Learn more about Peridotite vs Limestone in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Peridotite and Limestone, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Peridotite and Limestone
Here you can know more about Peridotite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Limestone consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey 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. Appearance of Peridotite is Rough and Shiny and that of Limestone is Rough and Banded. Properties of rock is another aspect for Peridotite vs Limestone. The hardness of Peridotite is 5.5-6 and that of Limestone is 3-4. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Limestone is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Peridotite is heat resistant, pressure resistant, wear resistant whereas Limestone is pressure resistant.
