Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
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 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. Flint vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Flint and Properties of Peridotite. Learn more about Flint vs Peridotite in the next section. The interior uses of Flint include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Flint and Peridotite, they have various applications in construction industry. The uses of Flint in construction industry include Arrowheads, Cutting tool, Spear points and that of Peridotite include As dimension stone, Cobblestones.
More about Flint and Peridotite
Here you can know more about Flint and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Peridotite consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Flint is Glassy or Pearly and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Flint vs Peridotite. The hardness of Flint is 7 and that of Peridotite is 5.5-6. The types of Flint 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 Flint and Peridotite is white. The specific heat capacity of Flint is 0.74 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.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
