Abstract

The enigmatic early Paleozoic tectonic setting of the Lachlan orogen in Australia has obscured reconstructions of east Gondwana. Recognition of an intraoceanic mafic island arc in this paper establishes the presence of a convergent plate boundary in the Tasmanides from the Early Ordo\ician to the Early Silurian. This in turn facilitates the updating of supercontinent correlations.
