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.
