This is a raster representing the base surface of the McBride Basalt Province, inferred from sparse data available, dominated by private water bore records. 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.
