 a left-stepping bend on a sinistral fault, a zone of extension or transtension is generated.Such bends are known as "releasing bends" or "extensional stepovers" and often form pull-apart basins or "rhombochasms".Examples of active pull-apart basins include the Dead Sea, formed at a left-stepping offset of the sinistral sense Dead Sea Transform system, and the Sea of Marmara, formed at a right-stepping offset on the dextral sense North Anatolian Fault system.
