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

Formation
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

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