Definition
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.
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
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Kimberlite and Diamictite Properties
Know all about Kimberlite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Kimberlite belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Kimberlite is Porphyritic whereas that of Diamictite is Clastic. Kimberlite appears Dull and Banded and Diamictite appears Banded. The luster of Kimberlite is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Diamictite is available in brown, buff colors. The commercial uses of Kimberlite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Diamictite are commemorative tablets, creating artwork, production of lime.
