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
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

Features
Host Rock for Lead, Is one of the oldest rock
Has High structural resistance against erosion and climate, Very fine grained rock
Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

More about Diamictite and Blueschist
Here you can know more about Diamictite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Blueschist consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Diamictite is Banded and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Diamictite vs Blueschist. The hardness of Diamictite is 2-3 and that of Blueschist is 3.5-4. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Blueschist are Metamorphic 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 Blueschist is white to grey. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Blueschist 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 Blueschist is impact resistant, pressure resistant.
