Basalts at Oceanic Divergent Boundaries. Most of Earth's basalt is produced at divergent plate boundaries on the midocean ridge system (see map). Here convection currents deliver hot rock from deep in the mantle. This hot rock melts as the divergent boundary pulls apart, and the molten rock erupts onto the sea floor.
