What type of rock is gabbro?
Gabbro is an intrusive, mafic, igneous rock.
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
Gabbro is an igneous rock with an intrusive origin. This means that the rock was formed when a body of magma pushed its way into the Earth's crust and formed an intrusion. This magma eventually cools and forms a coarse grained intrusive igneous rock. Gabbro can be found anywhere that a body of magma has risen and cooled.
