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
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Diamictite and Skarn Properties
Know all about Diamictite and Skarn properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Skarn belongs to Metamorphic Rocks.Texture of Diamictite is Clastic whereas that of Skarn is Earthy, Mud-rich, Rough. Diamictite appears Banded and Skarn appears Dull. The luster of Diamictite is grainy, pearly and vitreous while that of Skarn is waxy and dull. Diamictite is available in brown, buff colors whereas Skarn is available in black, brown, colourless, green, grey, white colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Skarn are creating artwork, gemstone, jewelry, metallurgical flux, source of magnesia (mgo).
