Formation

Norite 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.

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

Norite vs Gabbro 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 Norite and Gabbro Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. 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 Norite vs Gabbro information and Norite vs Gabbro characteristics in the upcoming sections.
