Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Pisolitic Oolite and Oncolitic Oolite
Features
Generally rough to touch, Is one of the oldest rock
Available in lots of colors, Generally rough to touch, Very fine grained rock
Archaeological Significance
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Quartzite vs Oolite 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. Quartzite vs Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Oolite. Learn more about Quartzite vs Oolite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Quartzite and Oolite, they have various applications in construction industry. The uses of Quartzite in construction industry 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 and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Quartzite and Oolite
Here you can know more about Quartzite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Oolite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Quartzite is Lustrous and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Quartzite vs Oolite. The hardness of Quartzite is 6-7 and that of Oolite is 3-4. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Oolite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Oolite is 0.65 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Oolite is heat resistant, wear resistant.
