Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

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.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

Oolite vs Wackestone 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 Wackestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Wackestone. Learn more about Oolite vs Wackestone in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Oolite and Wackestone, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Wackestone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Oolite and Wackestone
Here you can know more about Oolite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Wackestone consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Wackestone, 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, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Oolite is Rounded and Rough and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Oolite vs Wackestone. The hardness of Oolite is 3-4 and that of Wackestone is 2-3. The types of Oolite are Pisolitic Oolite and Oncolitic Oolite whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Wackestone is white. The specific heat capacity of Oolite is 0.65 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
