Tertiary sands of the Adelaide region

Abstract

The object of the field work was to visit areas where the onlap of Tertiary deposits on to basement is exposed in the vicinity of Adelaide, and to describe, as far as possible, the origin and nature of the non-marine sediments considered to be equivalent to the North Maslin Sands of the Noarlunga and Willunga Basins. The examination of new exposures in quarries to the NE of Adelaide, in the Highbury and Golden Grove areas, was undertaken, since these exposures now reveal vertical sections of up to 100ft in the Eocene non marine sands, which otherwise outcrop poorly.
