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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

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