Definition
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase
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

Archaeological Significance
Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Amphibolite 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. Amphibolite vs Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Diamictite. Learn more about Amphibolite vs Diamictite in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Amphibolite and Diamictite, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Amphibolite and Diamictite
Here you can know more about Amphibolite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Diamictite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite 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 Amphibolite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Diamictite is available in brown, buff colors. Appearance of Amphibolite is Foliated and that of Diamictite is Banded. Properties of rock is another aspect for Amphibolite vs Diamictite. The hardness of Amphibolite is 6-7 and that of Diamictite is 2-3. The types of Amphibolite are Hornblendite 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 Amphibolite is white to grey while that of Diamictite is light to dark brown. The specific heat capacity of Amphibolite is 0.84 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.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Diamictite is heat resistant, impact resistant.
