Jasperoid vs Trondhjemite

Definition

Definition

Jasperoid is a rare, peculiar type of metasomatic alteration of rocks
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

Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Jasperoid 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 Jasperoid and Trondhjemite Reserves. Jasperoid is a rare, peculiar type of metasomatic alteration of rocks. 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 Jasperoid vs Trondhjemite information and Jasperoid vs Trondhjemite characteristics in the upcoming sections.

Jasperoid vs Trondhjemite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others.
