As the plates diverge, upper mantle rock rises and undergoes decompression melting along the rift. Because the upper mantle is comprised of mafic rock, the subsequent melt of this rock produces a mafic magma. Basalt and its coarse-grained intrusive twin, gabbro, are produced when this mafic magma solidifies.
