Abstract

Micropalaeontological and biostratigraphic studies have been used to assist understanding of the stratigraphic and structural context of groundwater flow systems in the vicinity of the Woolpunda Groundwater Interception Scheme (WGIS) - a major area of saline groundwater discharge to the River Murray in the western Murray Basin. Structure was defined by tracing several stratigraphic markers in the Late Oligocene to Middle Miocene succession, including the Lepidocyclina foraminiferal zone and three clay or marl units of low permeability. A cross-section through the upper part of the Cainozoic sequence illustrates east- west arching gentle Middle to Late Miocene folding, and intermittent mild Cainozoic uplift. Arching and doming across the WGIS area is confirmed by a structure contour plot on top Renmark Group, and by limited drilling in the deeper Eocene and Cretaceous sediments. The arched structure apparently relates to draping of the Tertiary succession over a high of pre-Tertiary rocks related to the Hamley Fault. This high acts as a permeability barrier to the Renmark Group confined aquifer which thins significantly over it, promoting upward leakage into the water table aquifer, with resultant high saline discharge to the River Murray.
