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
Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Diamictite and Dunite
Here you can know more about Diamictite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Dunite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Dunite 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 Dunite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Diamictite is Banded and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Diamictite vs Dunite. The hardness of Diamictite is 2-3 and that of Dunite is 3.5-4. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Dunite are Not Available. 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 Dunite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Dunite 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 Dunite is heat resistant, pressure resistant, wear resistant.
