5.1 Formation

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

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.

Gabbro 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 Gabbro and Amphibolite Reserves. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. 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 Gabbro vs Amphibolite information and Gabbro vs Amphibolite characteristics in the upcoming sections.
