Abstract

Parallel shear, generated by sliding tongue and grooved boards past each other with clay on top produced, initially - in addition to the commonly recognised conjugate strike slip faults - a set of gently plunging folds at 30-45° to the wrench zone. Essentially vertical Riedel shears may subsequently become part of reverse drag structures as rotation of the clay, in response to the shearing couple, introduces a tensional component. A single right-lateral movement in the model has reproduced the orientation of the major faults and folds within the Fitzroy graben of the Canning Basin. Major features such as the offshore depression on the southern margin of the Leveque shelf and part of the Halls Creek mobile zone may have been produced, as simulated in the model, by major dextral wrenching and, in the case of the Leveque shelf, by later subsidence of basement rocks. Absorption of lateral movement by the Halls Creek mobile zone may account for the less deformed, more platform-like northeast Canning Basin.
