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
Gritstone or grit is a hard, coarse-grained, siliceous sandstone

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

All about Diamictite and Gritstone Properties
Know all about Diamictite and Gritstone properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite and Gritstone belong to Sedimentary Rocks.Texture of Diamictite is Clastic whereas that of Gritstone is Earthy. Diamictite appears Banded and Gritstone appears Layered and Foliated. The luster of Diamictite is grainy, pearly and vitreous while that of Gritstone is dull. Diamictite is available in brown, buff colors whereas Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones.
