The sedimentary sequence of the Pleistocene deposits of the Botany Basin were investigated using borehole samples and seismic data. A succession of environments from marine to terrestrial, separated by erosional surfaces, were recognized and, although absolute dating is not possible, a relative “minimum” chronology was established correlating erosional surfaces with sea-level fluctuations. Seismic surveys and borehole material from other sites indicate that the model presented here is applicable to other estuaries of N.S.W.  相似文献
