Definition

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

Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.

Felsite 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 Felsite 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 Felsite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. 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 Felsite information and Oolite vs Felsite characteristics in the upcoming sections.

More about Oolite and Felsite

Here you can know more about Oolite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Felsite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Oolite is Rounded and Rough and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Oolite vs Felsite. The hardness of Oolite is 3-4 and that of Felsite is 5-5.5. The types of Oolite are Pisolitic Oolite and Oncolitic Oolite whereas types of Felsite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Felsite is white. The specific heat capacity of Oolite is 0.65 kJ/Kg K and that of Felsite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Oolite is heat resistant, wear resistant whereas Felsite is heat resistant, impact resistant.
