Formation

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.  
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Oolite vs Anorthosite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Oolite and Anorthosite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Oolite vs Anorthosite information and Oolite vs Anorthosite characteristics in the upcoming sections.

Oolite vs Anorthosite 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 Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Anorthosite. Learn more about Oolite vs Anorthosite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Oolite and Anorthosite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.

More about Oolite and Anorthosite

Here you can know more about Oolite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Anorthosite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Anorthosite, 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, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Oolite is Rounded and Rough and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Oolite vs Anorthosite. The hardness of Oolite is 3-4 and that of Anorthosite is 5-6. The types of Oolite are Pisolitic Oolite and Oncolitic Oolite whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Anorthosite is white. The specific heat capacity of Oolite is 0.65 kJ/Kg K and that of Anorthosite is 0.84 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
