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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Peridotite vs Basanite 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 Basanite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Basanite . Learn more about Peridotite vs Basanite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Basanite include Decorative aggregates and Homes. Due to some exceptional properties of Peridotite and Basanite , they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Basanite include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Peridotite and Basanite
Here you can know more about Peridotite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Basanite 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 Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Peridotite is Rough and Shiny and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Peridotite vs Basanite . The hardness of Peridotite is 5.5-6 and that of Basanite is 7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Basanite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
