I I I I I I I I I I I I I I I I I I I I The formation consists of a 3-5 m basal sequence of porous dark brown poorly sorted limonitic quartz sandstone, minor conglomerate and breccia at places. Pebbles in the limonitic sandstone consist of well rounded quartz, chert and quartzite, where present, forms the base of the formation and contains angular blocks of fine quartzite, similar to that of in the underlying Proterozoic Wildman Siltstone. A geological reconnaissance was carried out by selected field traverses and aerial photo interpretation. The main objective of the survey was to locate dolomite in the out cropping Wildman Siltstone. No outcropping dolomite was found in this area. A detailed photo interpretation was also done on the area to locate photo lineaments for drilling targets. The following three geological elements were considered to be potential environments suitable for the development of aquifer in the Wildman Siltstone and Cretaceous sediments. These are: 1. 2. 3 Dolomitic and coarse grained arenaceous interbeds of Wildman Siltstone, Possible Siltstone above, and faulting and brecciation within the Wildman particularly in the lithologies indicated Coarse grained arenaceous sediments of immediately above the unconformity Wildman Siltstone. basal member lying developed on the The aim of the hydrogeological and geophysical investigation was therefore to explore and define the above three environments throughout the area of investigation. 26:INV2
