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
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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