Abstract
We show that fractures produced in an elastic, homogeneous lithospheric plate by stress generated by wedging of deepseated igneous mass(es) are comparable with the major fracture geometry and rift valley formation associated with the Red Sea, Gulf of Aden and East African Ridges; and that the formation and evolution of certain triple junction fracture geometry (FFR to RRR types) can also be related to stress generated around an oblate magmatic body.
