Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Peridotite vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Suevite. Learn more about Peridotite vs Suevite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Peridotite and Suevite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Peridotite and Suevite
Here you can know more about Peridotite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Suevite 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 Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Peridotite is Rough and Shiny and that of Suevite is Banded. Properties of rock is another aspect for Peridotite vs Suevite. The hardness of Peridotite is 5.5-6 and that of Suevite is 5.5. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white while that of Suevite is light to dark brown. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Suevite is 0.92 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 Suevite is heat resistant.
