Abstract

Cores were taken in the investigation bore RN041216 to examine the nature of the Koolpinyah Dolostone aquifer and the overlying Darwin Formation. Open fractures and partially dissolved calcite veins were the main features that were likely to constitute an aquifer. The dolostone was mostly a slightly weathered to fresh, hard rock with isolated zones of fractures. Even at the deepest point cored some fractures were iron stained indicating that water moves through them. The Darwin Formation is strongly weathered. In the sandstone most inter-granular spaces are clay filled resulting in a relatively low permeability. Two cross-cutting iron oxide breccias cut the sandstone. They have formed along fractures and are likely avenues for bypass recharge to occur.,
