Much has recently been written about the compressional theory for the origin of Rift Valleys in Africa, and the supposed reversed faulting of their sides, and so little has been published about the evidence for their normal faulting, that those who have not had the opportunity of working in rift valley areas may possibly obtain a rather one-sided view of the problem. It seems fair, therefore, to ask for space in the Geological Magazine to reflect on the case against the compressional theory, and to bring forward in general some of the evidence in support of normal faulting.
