The Lucas Outlier: a Western Australian update

Abstract

The Lucas Outlier was previously interpreted as an outlying component of the Canning Basin that crossed the Western Australian border into the Northern Territory (Hocking, 1994). Recent fieldwork and detrital geochronology (Wingate et al., 2021) now suggest a much older age for the lowest and dominant component of the Lucas Outlier than previously thought, suggesting a closer relationship with the underlying Murraba Basin, a component of the Centralian Superbasin.
