A PhD study into the Hiltaba Suite granites found that the stratigraphic term ‘Suite’ is wrong for this Association and that they are divisible into at least four Supersuites. This includes two Supersuites with A-type affinities and two with I-type characteristics. A spatial variation of geothermal gradients plus source ‘basement’ is indicated, and these may have bearing on resultant coeval mineralisation, with the eastern Olympic Cu-Au Province associated with the Roxby A-type Supersuite, and the Central Gawler Gold Province associated with the Malbooma I-type Supersuite.
