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
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Diamictite and Quartzite Properties
Know all about Diamictite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Diamictite is Clastic whereas that of Quartzite is Foliated, Granular. Diamictite appears Banded and Quartzite appears Lustrous. The luster of Diamictite is grainy, pearly and vitreous while that of Quartzite is vitreous. Diamictite is available in brown, buff colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
