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
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Harzburgite 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 Harzburgite
Here you can know more about Diamictite and Harzburgite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Harzburgite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Harzburgite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Harzburgite is available in dark greenish - grey colors. Appearance of Diamictite is Banded and that of Harzburgite is Rough and Shiny. Properties of rock is another aspect for Diamictite vs Harzburgite. The hardness of Diamictite is 2-3 and that of Harzburgite is 5.5-6. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Harzburgite are Ultramafic 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 Harzburgite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Harzburgite is 1.25 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 Harzburgite is heat resistant, pressure resistant, wear resistant.
