    Abstract

    A new palaeomagnetic study of the Mereenie Sandstone reveals a remanence direction different from the previously published result. The palaeopoles obtained from this formation and the overlying Devonian rock formations link with the existing palaeopoles from both the Lachlan Fold Belt (LFB) and cratonic Australia, and form a single mid-Late Palaeozoic apparent polar wander path (APWP) for Australia. It is suggested that the LFB has been joined to cratonic Australia since at least Devonian times, the Mereenie Sandstone is probably of mostly Silurian age and that the Parke Siltstone and Hermannsburg Sandstone are of mid-Devonian age. -from Authors
