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.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Peridotite vs Pantellerite 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 Pantellerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Pantellerite. Learn more about Peridotite vs Pantellerite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Pantellerite include Not yet used. Due to some exceptional properties of Peridotite and Pantellerite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Pantellerite include Na.
More about Peridotite and Pantellerite
Here you can know more about Peridotite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Pantellerite 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 Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Peridotite is Rough and Shiny and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Peridotite vs Pantellerite. The hardness of Peridotite is 5.5-6 and that of Pantellerite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Pantellerite are Pantelleritic Ignimbrite. 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 Pantellerite is unknown. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Pantellerite is Not Available. 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 Pantellerite is heat resistant.
