Linking crustal reworking to terrane accretion

The Strangways Metamorphic Complex in central Australia is a key terrane in models for the evolution of the Australian continent. The Arunta Complex preserves a long-lived (<em>c</em>. 1700–320 Ma) record of crustal reworking, the drivers of which are the subject of considerable debate. Pressure–temperature data and <em>in situ</em> monazite geochronology constrain the reworking to be coincident with the <em>c</em>.1645 Ma Liebig Orogeny. This suggests that reworking in the Strangways Metamorphic Complex is related to terrane accretion rather than other factors such as anomalous enrichment in high-heat-producing elements or within-plate processes.
