Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Claystone vs Quartzite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Claystone vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Quartzite. Learn more about Claystone vs Quartzite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Claystone and Quartzite, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Claystone and Quartzite
Here you can know more about Claystone and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Quartzite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Claystone is Rough and Dull and that of Quartzite is Lustrous. Properties of rock is another aspect for Claystone vs Quartzite. The hardness of Claystone is 3.5-4 and that of Quartzite is 6-7. The types of Claystone are Not Available whereas types of Quartzite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Quartzite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Quartzite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
