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

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

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