The work undertaken on the Permian-Triassic transition in China, in collaboration with Roland Mundil, Paul Renne and Ken Ludwig of the Berkeley Geochronology Centre, led to establishment of robust ages for the mass extinction level and the Permian-Triassic Boundary as defined at the Global Stratotype Section and Point (GSSP) at Meishan, South China. More fundamental outcomes of this work in China led to refinement of a new technique of annealing and chemically abrading zircon crystals prior to dating of single zircon crystals from volcanic ash-fall tuffs.

Deposition of coal-bearing sequences in the southern Sydney Basin apparently commenced a few million years before deposition of similar sequences in the Bowen Basin but deposition ceased at the same time in both regions.Isotopic data and elemental contents are not supportive of a model in which crustal contamination is the dominant process in magma petrogenesis, but do not exclude contamination with Sr-rich material having a low values.
