Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Granulite vs Boninite 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 Granulite and Boninite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. 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 Granulite vs Boninite information and Granulite vs Boninite characteristics in the upcoming sections.
