Abstract: The gravity anomaly in the Amik Plain, Hatay, Turkey, is similar tothose in the Rift Valleys of Africa. The tectonic situation around the AmikPlain is also similar to those around the Rift Valleys. Thus, it is very likelythat the Amik Plain is the continuation of the Rift Valleys. A theory suggested by G. F. S. HILLS to explain the development of the rift valleys ismodified and applied to this area, and the possible structure under thesedimentary cover is given.
