Formation

Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.   
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Gabbro vs Basalt 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 Basalt Reserves. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. 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 Basalt information and Gabbro vs Basalt characteristics in the upcoming sections.
