WebVesicular Basalt: 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. Gabbro is a major component of the lower oceanic crust. Basalt is a fine-grained mafic igneous rock. It is commonly vesicular and aphanitic.
