Archaeological Significance
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Peridotite vs Claystone 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 Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Claystone. Learn more about Peridotite vs Claystone in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Peridotite and Claystone, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Peridotite and Claystone
Here you can know more about Peridotite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Claystone 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 Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Peridotite is Rough and Shiny and that of Claystone is Rough and Dull. Properties of rock is another aspect for Peridotite vs Claystone. The hardness of Peridotite is 5.5-6 and that of Claystone is 3.5-4. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Claystone is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Claystone is 0.92 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 Claystone is heat resistant, impact resistant.
