1.1 Definition

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

Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

5 Formation

5.1 Formation

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

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

All about Quartzite and Shale Properties

Know all about Quartzite and 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 Shale belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Shale is Clastic, Splintery. Quartzite appears Lustrous and Shale appears Muddy. The luster of Quartzite is vitreous while that of Shale is dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Shale is available in black, brown, buff, green, grey, red, yellow 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 Shale are creating artwork, pottery.
