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
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

More about Diamictite and Soapstone
Here you can know more about Diamictite and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Soapstone consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Diamictite is Banded and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Diamictite vs Soapstone. The hardness of Diamictite is 2-3 and that of Soapstone is 1. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Soapstone 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 Soapstone is black. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Soapstone is 0.88 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 Soapstone is heat resistant, pressure resistant.
