Data presented elsewhere in this issue (Page, Blake, and Mahon, 1976) provide some of the first ages from The Granites-Tanami Block. Unfortunately it did not prove possible to date or even adequately sample the weathered low grade metasediments and metavolcanics of the Tanami complex, clearly the oldest exposed component of the block. For this reason age data pertaining to the Halls Creek Group, the suggested correlative of the Tanami complex in the Kimberley region to the northwest (Page et al., this volume, Fig. 1), are now reinterpreted in an attempt to arrive at a reasonable estimate of the age of these old rocks. In considering the available information on the geochronology of this part of Australia it is also pertinent to review the age of the Whitewater Volcanics, Castlereagh Hill Porphyry and Bow River Granite, which form a Lower Proterozoic comagmatic suite overlying and intruding the Halls Creek Group in the Halls Creek Mobile Zone.
