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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Peridotite vs Jaspillite 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 Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Jaspillite. Learn more about Peridotite vs Jaspillite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Peridotite and Jaspillite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Jaspillite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Peridotite and Jaspillite
Here you can know more about Peridotite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Jaspillite 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 Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Peridotite is Rough and Shiny and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Peridotite vs Jaspillite. The hardness of Peridotite is 5.5-6 and that of Jaspillite is 3. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Jaspillite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Jaspillite is 3.20 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 Jaspillite is heat resistant, impact resistant, wear resistant.
