The major aquifers of the Maranoa-Balonne-Condamine subregion are associated with the:
- antecedent systems that form paleochannel infill and broad alluvial cover over much of the subregion
- fractured rock aquifers within the Main Range Volcanics
- sedimentary rocks of the GAB
- major rivers (i.e. the Condamine, Balonne, Dumaresq and Macintyre rivers).
A detailed description of the key aquifer systems is in Section 1.1.4 of companion product 1.1 for the Maranoa-Balonne-Condamine subregion (Welsh et al., 2014). The temporal sequence of geological units and relative groundwater flow potential are identified in a summary of hydrostratigraphic relationships (Figure 9) (Ransley and Smerdon, 2012).
