Abstract
The type area of the Corunna Group of sediments of Carpentarian age, outcropping in the northeast of Eyre Peninsula, South Australia, was mapped, divided into members and the sedimentary history determined.
It was decided that suitable subdivisions were; the lower conglomerate member, the lower green sandstone member, the red conglomerate member, the white conglomerate member and the upper green sandstone member. A major unconformity was found between the red and white conglomerate members.
The sediments were deposited in a trough which opened to the sea to the north. Tectonic activity dictated the type of sediment, whether marine or terrestrial, deposited. Most of the sediment supply was from the east for the red conglomerate member, and from the southwest for the white conglomerate member.
The sediments were then faulted, folded and intruded by dykes during the Wartakan phase of tectonic and igneous activity.
