Summary:

The borefield region is located within the Gunnedah Basin, which predominantly comprises Permian Age metasediments and volcanics and is overlain by Quaternary alluvial deposits within the valleys. The Permian metasediments in the region include the Maules Creek Formation which outcrop further to the east of the Boggabri Volcanics and are mined for coal at Boggabri, Tarrawonga and Maules Creek mines. The volcanic units belong to the Boggabri Volcanics and include basalt, trachyte and rhyolite flows and pyroclastics. In the borefield region the Boggabri Volcanics form the basement rock underlying the alluvium and bordering the alluvial plain.

The alluvial deposits in the proposed borefield area are associated with the Namoi River and the lower reaches of ‘Nagero’ and Bollol Creeks. The thickness of alluvium has been recorded exceeding 125 m deep in places but may typically be between 25 to 75m thick. Within alluvial creek embayments bordered by the volcanics, such as along Bollol Creek and ‘Nagero’ Creek the alluvial pile may be up to 30m deep.

The alluvial sediments are recognised as belonging to two formations, although they are not always distinguishable. The uppermost Narrabri Formation predominantly consists of clay with minor sands and gravels. Underlying the Narrabri Formation is the Gunnadah Formation which typically comprises gravel and sand with minor clay beds. The geological logs from registered bores in the alluvium and from the Boggabri test production bores discriminate an upper 8 – 25 m largely consisting of clay which is floodplain sediments deposited in low energy environment, and possibly the Narrabri Formation. The sand and gravel layers are likely to be channel deposits along the meandering river systems and commonly are clayey and silty in composition and poorly sorted. Gravel clasts are typically sub-angular to subrounded and are probably derived from volcanics and metasediments in the local region. Interlayed clay – silt layers are low energy floodplain sediments.
