Formation
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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.

Shonkinite vs Peridotite 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. Shonkinite vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shonkinite and Properties of Peridotite. Learn more about Shonkinite vs Peridotite in the next section. The interior uses of Shonkinite include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Shonkinite and Peridotite, they have various applications in construction industry. The uses of Shonkinite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Peridotite include As dimension stone, Cobblestones.
More about Shonkinite and Peridotite
Here you can know more about Shonkinite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Peridotite consists of mineral content and compound content. The mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Shonkinite vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Shonkinite is available in brown, buff, cream, green, grey, pink, white colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Shonkinite is Banded and Foilated and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Shonkinite vs Peridotite. Hardness of Shonkinite and Peridotite is 5.5-6. The types of Shonkinite are Not Available whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shonkinite and Peridotite is white. The specific heat capacity of Shonkinite is 0.92 kJ/Kg K and that of Peridotite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shonkinite is heat resistant, impact resistant, wear resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
