Evolution of Salt Anticlines and Salt Domes in the Amadeus Basin, Central Australia

It is proposed that anticlines and diapirs in the northern part of the Amadeus basin in central Australia were initiated at an early stage in the sedimentary history of the basin and that they continued to grow as the result of salt flowage in response to sedimentary loading during late Proterozoic and early Paleozoic sedimentation. It is further proposed that these structures were accentuated and modified during the Pertnjara orogeny in upper Paleozoic time. However, they were not formed at the time of the orogeny, as was heretofore supposed.
