Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Features
Constitutes upper part of the Earth's mantle, Generally rough to touch, Host rock for Diamond, Is one of the oldest rock
Host Rock for Lead, Is one of the oldest rock
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Peridotite vs Diamictite 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 Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Diamictite. Learn more about Peridotite vs Diamictite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Peridotite and Diamictite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Peridotite and Diamictite
Here you can know more about Peridotite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Diamictite 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 Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Diamictite is available in brown, buff colors. Appearance of Peridotite is Rough and Shiny and that of Diamictite is Banded. Properties of rock is another aspect for Peridotite vs Diamictite. The hardness of Peridotite is 5.5-6 and that of Diamictite is 2-3. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white while that of Diamictite is light to dark brown. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
