5 Formation

5.1 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.

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Harzburgite vs Amphibolite 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 Amphibolite Reserves. Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. 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 Amphibolite information and Harzburgite vs Amphibolite characteristics in the upcoming sections.
