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

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