Definition
Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline
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
Theralite 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 is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

More about Theralite and Diamictite
Here you can know more about Theralite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Diamictite consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, 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 Theralite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Theralite is available in dark grey to black colors whereas, Diamictite is available in brown, buff colors. Appearance of Theralite is Veined and Shiny and that of Diamictite is Banded. Properties of rock is another aspect for Theralite vs Diamictite. The hardness of Theralite is 7 and that of Diamictite is 2-3. The types of Theralite are Teschenite and Essexite 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 Theralite is white while that of Diamictite is light to dark brown. The specific heat capacity of Theralite is 0.74 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.Theralite is impact resistant, pressure resistant, wear resistant whereas Diamictite is heat resistant, impact resistant.
