Quartzite characteristics
"Grains arranged in parallel layers" describes a characteristic of quartzite. The right answer is c. Sandstone that is quartz-rich undergoes metamorphism to become quartzite, a metamorphic rock.The grains may become closely packed and arranged in parallel strata as a result of this process, giving quartzite a banded or foliated look.The mineral composition of quartzite is predominantly quartz (quartz content in the rock reaches 88-98%), with iron hydroxides (2-3%), silicon and chalcedony (4-5%). The stone also contains impurities of mica, talc, feldspar, and other minerals.Also, the harder the quartzite, the more difficult it may be for someone to cut and finish the material, hence the higher prices. Quartzite starts at about $60 per square foot while granite starts at about $50 per square foot. If you are remodeling an entire kitchen, prices will vary for all the different elements.

The streak of Quartzite is white whereas its fracture is uneven, splintery or conchoidal. Luster of Quartzite is the interaction of light with the surface of Quartzite. Luster of Quartzite is vitreous.Chert (/ ˈ tʃ ɜːr t /) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood.. Chert is typically composed of the petrified remains of ...
Quartz, pyroxene, feldspar, and other minor inclusions The chemical composition looks like this: (Na,Ca)(Al,Si)4O8 with Na (30-50%) and Ca (70-50%).
