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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Peridotite vs Oolite 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 Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Oolite. Learn more about Peridotite vs Oolite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Peridotite and Oolite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Peridotite and Oolite
Here you can know more about Peridotite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Oolite 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 Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Peridotite is Rough and Shiny and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Peridotite vs Oolite. The hardness of Peridotite is 5.5-6 and that of Oolite is 3-4. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Oolite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Oolite 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 Oolite is heat resistant, wear resistant.
