The Adelaide Rift Complex, a sedimentary basin in South Australia, has a long history spanning over 300 million years from the Neoproterozoic to the Cambrian. Over 100 individual formations make up the basin fill, documenting its geologic evolution from incipient rift to passive margin, and recording a wide range of depositional environments. The basin's strata are significantly affected by syndepositional salt tectonics and later structural deformation, creating a well-exposed natural laboratory in which to examine sedimentary systems that are rarely exposed elsewhere. This report book briefly summarises the basin’s geology, focussing on sedimentology, and provides a starting point for further research through reviews made of both recent and older literature. The deposits discussed here may serve as analogues for similar depositional systems in the subsurface that are involved during petroleum exploration and development; some relevant analogues are also discussed, focussing on those that also have a component of salt-sediment interaction. This publication, facilitated by the Geological Survey of South Australia, is based on the literature review done for the author’s Ph.D. thesis entitled "Sedimentology, provenance, and salt-sediment interaction in the Ediacaran Pound Subgroup, Flinders Ranges, South Australia". That complete thesis is available online from the University of Adelaide Library (https://digital.library.adelaide.edu.au/dspace/handle/2440/105869).
