4.1: Classification of Igneous Rocks - Geosciences LibreTexts
Gabbro is a coarse-grained mafic igneous rock, made with mainly mafic minerals like pyroxene and only minor plagioclase. Because mafic lava is more mobile, it is less common than basalt. …

What is the Difference Between Gabbro and Basalt
See more on pediaa.comGabbro is a type of intrusive igneous rock that forms deep beneath the Earth’s crust. This rock type forms due to the slow cooling of magnesium-rich and iron-rich magma. The final product of this cooling is a holocrystalline mass. Chemically, slow-cooling, coarse-grained gabbro is equal to rapid-cooling, fine-grained basal…- Estimated Reading Time: 4 mins
