Gabbro and Basalt are Related The difference between the two rock types is their grain size. Essentially gabbro is the intrusive plutonic equivalent of basalt but whereas basalt is often remarkably homogeneous in mineralogy and composition gabbros are exceedingly variable. As dikes composed chiefly of calcic plagioclase and clinopyroxene.
