Karst system developed in salt layers of the Lisan Peninsula, Dead Sea, Jordan

The Lisan Peninsula, Jordan, is a massive salt layer accumulated in the inner part of the Dead Sea's precursory lakes. This tongue-shaped, emergent land results in a salt diapir uplifted in the Dead Sea strike-slip regional stress field and modified by the water level fluctuations of the last lake during the Holocene. These two elements, associated with dissolution caused by rainfall and groundwater circulation, resulted in an authentic karst system. Since the 1960s, the Dead Sea lowering of 80 cm to 1 m per year caused costly damages to the industrial plant set up on the peninsula. The Lisan karst system is described in this article and the components of the present dynamic setting clarified.
