Dolerite is the name given to the medium-grained intrusive basic igneous rock commonly found in dykes and sills; in North America and continental Europe it is often referred to as diabase, but many authors restrict this term to altered dolerite.

Hatch et al. () suggest that both of these terms be replaced by microgabbro (see Basic igneous rocks). dolerite [ In the United States, a dark igneous rock, the mineral constituents of which are not determinable megascopically] Dolerit m COVID Resources.

It is rich in magnesium and iron, and originally found under the crust of volcanoes. Dikes and sills in igneous rock are often made of diabase. References This page was last changed on 12 Julyat The dolerite dyke swarm of Mongo, Guéra Massif | Figure TiO 2 vs.

The average trend of these dykes is N40°W–S40°E. At some localities, the dolerite dykes are seen to cut across the quartz reefs.
