This guide concentrates on slope depositional processes and sediments of the largely deltaic slope and submarine fan facies Wilpena Group at the Patsy Springs Canyon and the Fortress Hill Canyon Complex. Summarised stratigraphic sections outline what are interpreted as 3 offlapping (regressive) and onlapping (transgressive) terrigenous and mixed carbonate - terrigenous systems within the Wilpena Group and lower Cambrian Hawker Group. Each offlapping cycle represents a largely regressive delta / prograding slope complex, at least 1 of which (the Brachina Formation) has been incised by a major submarine canyon complex during a relative sea level fall. The canyons subsequently have been backfilled and buried by an onlapping basinal fan sequence, the Wonoka Formation.
