1.1 Definition

Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

5 Formation

5.1 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.

Tachylite 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 Tachylite 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 Tachylite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. 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 Tachylite information and Oolite vs Tachylite characteristics in the upcoming sections.
