Which other igneous rock is closest to diabase in mineral composition? Diabase (dolerite) is a dark-colored igneous rock. It is compositionally equivalent to gabbro and basalt but texturally between them. Diabase is a common rock type. It occurs mostly in shallow intrusions (dikes and sills) of basaltic composition.

12. Basalt per definition is a fine grained rock (that is, you can't see the individual crystals with the naked eye, aka aphanitic) with a certain chemical composition. The coarse grained form of this rock is called a gabbro. A diabase (or dolerite) is something in between, but let's ignore it for the meanwhile for the sake of simplicity.
