5.1 Formation
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

Picrite vs Oolite 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 Picrite and Oolite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. 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 Picrite vs Oolite information and Picrite vs Oolite characteristics in the upcoming sections.

Picrite vs Oolite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others.
