This interpretation was conducted by a hydrogeologist from Geoscience Australia. Caveats • This is just one model, based on sparse data and considerable palaeotopographic interpretation • This model relies on the input datasets being accurate. However it is noted that substantial uncertainty exists both in the location of private bores and the use of drillers’ logs for identifying stratigraphic contacts. • The location of palaeothalwegs is imprecise, and often it is only indicative of the presence of a palaeovalley. • The purpose of this model is for visualisation purposes, so should not be considered a definitive depth prediction dataset. {"type": "Polygon", "coordinates": [[[144.5, -20.25], [146.35, -20.25], [146.35, -19.3], [144.5, -19.3], [144.5, -20.25]]]} 144.5 146.35 -20.25 -19.3 EARTH SCIENCES EFTF Exploring for the Future GEOLOGY Nulla Basalt Published_External Upper Burdekin geology groundwater hydrogeology modelled geologic surface Download the data (tif) [49.4 MB] documentDigital Download the data (tif) [49.4 MB] ZIP Upper Burdekin Groundwater Raster Products WMS documentDigital Upper Burdekin Groundwater Raster Products WMS WMS Upper Burdekin Groundwater Raster Products WMTS documentDigital Upper Burdekin Groundwater Raster Products WMTS HTML Upper Burdekin Groundwater Raster Products WCS documentDigital Upper Burdekin Groundwater Raster Products WCS WCS
