The Lisan Peninsula is located within the Dead Sea basin which represents the plate boundary between African and Arabian plates . This basin constitutes a good example of a pull - apart basin because of its large dimensions , its structural simplicity and its active subsidence . The gravity data reveal that the Dead Sea basin can be divided into segments, each of them about 30 km long in N -S direction , where the Lisan Peninsula represents the deepest one (9 km thick Pleistocene sediments ), overlying about 6 km thick Mesozoic sediments . In addition . 20 km of extension was predicted along the Dead Sea basin , which indicates that the Dead Sea basin should be about 3.3 Ma in age . Furthermore . the Precambrian basement under the Lisan area is characterized by high susceptibility contrast that is related to continuous tectonic activity in the region . 展开更多
