Formation

Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Oil shale and Quartzite Properties

Know all about Oil shale and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Oil shale is Splintery whereas that of Quartzite is Foliated, Granular. Oil shale appears Muddy and Quartzite appears Lustrous. The luster of Oil shale is dull while that of Quartzite is vitreous. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Oil shale are an oil and gas reservoir 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.
