Formation

Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.  
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Gabbro vs Gossan 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 Gossan Reserves. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan information and Gabbro vs Gossan characteristics in the upcoming sections.
