Abstract

The central and northern parts of the Adelaide fold belt in the Flinders Ranges, South Australia, consist of a sequence of Neo-Proterozoic-Cambrian sediments overlying a Meso-Proterozoic basement complex, both of which were mildly deformed in an intracratonic setting during the ~500 Ma Delamerian orogeny. The fold belt lies within a prominent heat flow anomaly (average heat flows of ~90 mWm-2) reflecting extra-ordinary enrichments in heat producing elements in the Meso-Proterozoic basement, suggesting that anomalous thermal regimes may have been significant in localising Delamerian deformation. However, spatial variations in deformation intensity correlate more closely with variations in the..
