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

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