Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
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
Lamprophyre formation takes place deep beneath the Earth’s surface at around 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 Lamprophyre and Diamictite Properties
Know all about Lamprophyre and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Lamprophyre is Porphyritic whereas that of Diamictite is Clastic. Lamprophyre appears Dull, Banded and Foilated and Diamictite appears Banded. The luster of Lamprophyre is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Lamprophyre 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 Lamprophyre 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.
