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
An iron rich extrusive rock found as a member of the alkali basalt magma series

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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