1.1 Definition

Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

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

5.1 Formation

Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, 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 Minette and Diamictite Properties

Know all about Minette and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Minette belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Minette is Porphyritic whereas that of Diamictite is Clastic. Minette appears Dull, Banded and Foilated and Diamictite appears Banded. The luster of Minette is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Minette 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 Minette 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.
