Diabase, also called dolerite or microgabbro, is a mafic, holocrystalline, subvolcanic rock chemically equivalent to volcanic basalt or plutonic gabbro. It typically forms in shallow intrusive bodies such as dikes and sills rather than in deep crustal environments.

Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock chemically equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass).
