Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
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
Lherzolite 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 Lherzolite and Diamictite
Here you can know more about Lherzolite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Diamictite consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite 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 Lherzolite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Diamictite is available in brown, buff colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Diamictite is Banded. Properties of rock is another aspect for Lherzolite vs Diamictite. The hardness of Lherzolite is 6.5 and that of Diamictite is 2-3. The types of Lherzolite are Garnet Lherzolite 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 Lherzolite is white while that of Diamictite is light to dark brown. The specific heat capacity of Lherzolite is 0.95 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.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Diamictite is heat resistant, impact resistant.
