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.

Foidolites 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.

Oolite vs Foidolite 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 Foidolite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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.
