Harzburgite vs Felsite


Felsite vs Harzburgite


Definition

Definition
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine   
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
Harzburgite 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.

Harzburgite 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 Harzburgite and Felsite Reserves. Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine. 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 Harzburgite vs Felsite information and Harzburgite vs Felsite characteristics in the upcoming sections.
