Geological reconnaisance on the Macdonald and Rawlinson sheet areas has shown an aggregate thickness of 27,000 feet of Precambrian sedimentary rocks. These rocks have been divided into Lower and Upper Proterozoic but only on the north-east corner of the Macdonald sheet is the unconformity between the two sequences visible. Possible Archaean gneiss and quartzite have also been differentiated in the north-east Macdonald area, These rocks are similar to those in the Arunta Complex of the Alice Springs area. No relationship is visible between these rocks and those mapped as Lower Proterozoic.
