Description :
The Bellinger River catchment in the New England Fold Belt on the mid-north coast of New South Wales is characterized by an assemblage of stepped late Quaternary alluvial units. The AA. examine the stratigraphy and chronology of these alluvial units. They re-examine the initial chronology presented by Warner (1970, 1972), but more importantly investigate the chronostratigraphy of polycyclic floodplains and terraces. They conclude that valley confinement produces conditions favourable for the accumulation of more than one contemporaneously forming floodplain surfaces as well as surfaces vertically accreting at different rates.
