Trondhjemite vs Oolite


Definition

Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite   
Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.

Formation

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.   
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Oolite vs Trondhjemite 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 Trondhjemite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.. 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 Trondhjemite information and Oolite vs Trondhjemite characteristics in the upcoming sections.
