5 Formation
5.1 Formation
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Marl and Quartzite Properties

Know all about Marl and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Marl belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Marl is Earthy whereas that of Quartzite is Foliated, Granular. Marl appears Rough and Dull and Quartzite appears Lustrous. The luster of Marl is dull while that of Quartzite is vitreous. Marl is available in beige, brown, green, grey, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Marl are creating artwork, soil conditioner 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.
