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
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

Features
Host Rock for Lead, Is one of the oldest rock
Has High structural resistance against erosion and climate, Very fine grained rock
Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Diamictite vs Epidosite 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 Epidosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Epidosite. Learn more about Diamictite vs Epidosite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration. Due to some exceptional properties of Diamictite and Epidosite, 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 Epidosite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Diamictite and Epidosite
Here you can know more about Diamictite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Epidosite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Diamictite is Banded and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Diamictite vs Epidosite. The hardness of Diamictite is 2-3 and that of Epidosite is 6. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Epidosite is white to grey. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Epidosite is 0.84 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 Epidosite is heat resistant, pressure resistant, wear resistant.
