Formation
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.
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 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. Anorthosite vs Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Oolite. Learn more about Anorthosite vs Oolite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Anorthosite and Oolite, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Anorthosite and Oolite
Here you can know more about Anorthosite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Oolite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Anorthosite vs Oolite. The hardness of Anorthosite is 5-6 and that of Oolite is 3-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Oolite is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Oolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Oolite is heat resistant, wear resistant.
