Tectonic study and structural analyses of Al-Sin Faults Zone show that it is composed from a group of E-W to NE-SW pure normal faults, characterizing by increasing of vertical throw from east to west. Formation and evolution of Al-Sin Faults Zone principally related to coastal Range uplift during Levant Fault formation in lower Pliocene. Al-Sin Faults Zone used heritable faults from lower Cretaceous, witch interpret the important deviation of its direction from E-W to NE-SW.
