Mount Carmel is the surface expression of one of the main tectonic elements in Israel. The structure is old and probably started to evolve during upper Paleozoic. Model studies of the magnetic and gravity highs associated with this feature show that they are caused by two different bodies. The structure, which is continuous from land (perhaps from as far as the Jordan rift zone) to the sea, was investigated by using offshore geophysical data supported by data from land, and an evolutionary model is proposed.
