The third basalt-forming environment is a continental environment where a mantle plume or hotspot delivers enormous amounts of basaltic lava through the continental crust and up to Earth's surface. These eruptions can be from either vents or fissures.They have produced the largest basalt flows on the continents.t has a composition similar to gabbro.
