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

Archaeological Significance
Formation
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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Gritstone and Diamictite Properties
Know all about Gritstone and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone and Diamictite belong to Sedimentary Rocks.Texture of Gritstone is Earthy whereas that of Diamictite is Clastic. Gritstone appears Layered and Foliated and Diamictite appears Banded. The luster of Gritstone is dull while that of Diamictite is grainy, pearly and vitreous. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Diamictite is available in brown, buff colors. The commercial uses 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 and that of Diamictite are commemorative tablets, creating artwork, production of lime.
