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
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Ijolite 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.

More about Diamictite and Ijolite
Here you can know more about Diamictite and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Ijolite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Diamictite is Banded and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Diamictite vs Ijolite. The hardness of Diamictite is 2-3 and that of Ijolite is 5.5-6. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Ijolite are Alkaline rock. 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 Ijolite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Ijolite 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 Ijolite is heat resistant, impact resistant, wear resistant.
