Archaeological Significance
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

All about Quartzite and Jaspillite Properties
Know all about Quartzite and Jaspillite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Jaspillite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Jaspillite is Banded, Trellis. Quartzite appears Lustrous and Jaspillite appears Banded and Glassy. The luster of Quartzite is vitreous while that of Jaspillite is earthy. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Jaspillite is available in red, reddish brown colors. The commercial uses 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 and that of Jaspillite are creating artwork, jewelry.
