5 Formation
5.1 Formation
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.
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.

Rhyolite 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 Rhyolite and Oolite Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. 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 Rhyolite vs Oolite information and Rhyolite vs Oolite characteristics in the upcoming sections.

Rhyolite 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. Rhyolite vs Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhyolite and Properties of Oolite. Learn more about Rhyolite vs Oolite in the next section.
