Definition
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
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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 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. Diamictite vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Peridotite. Learn more about Diamictite vs Peridotite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diamictite and Peridotite, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Peridotite include As dimension stone, Cobblestones.
More about Diamictite and Peridotite
Here you can know more about Diamictite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Peridotite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz 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 Diamictite vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Diamictite is Banded and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Diamictite vs Peridotite. The hardness of Diamictite is 2-3 and that of Peridotite is 5.5-6. The types of Diamictite are Bedded Diamictite and Laminated Diamictite 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 Diamictite is light to dark brown while that of Peridotite is white. The specific heat capacity of Diamictite is 0.75 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.Diamictite is heat resistant, impact resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
