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

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.

All about Diamictite and Blueschist Properties
Know all about Diamictite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Diamictite is Clastic whereas that of Blueschist is Foliated. Diamictite appears Banded and Blueschist appears Dull and Banded. The luster of Diamictite is grainy, pearly and vitreous while that of Blueschist is dull. Diamictite is available in brown, buff colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
