摘要:
It is difficult to determine the ages of thick stratigraphic units in different parts of the Tablelands Complex in New England, because of a scarcity of fossils and the effects of superposed deformations. Many problems disappear if it is assumed that the Silverwood Group is in part Lower Permian and that its Ordovician and Devonian fossils are in olistoliths derived from the Thanes Creek Slate to the W of the Con‐damine Fault. With that assumption it is possible to divide the Tablelands Complex into four main layers, which in upward order consist of the following sedimentary associations: (1) Woolomin (?Devonian), (2) Sandon and Beenleigh (Late Devonian to Carboniferous), (3) Nambucca, Silverwood and Coffs Harbour (?Late Carboniferous to Early Permian), and (4) Dummy Creek (Late Permian). The four layers can be extended to include sets of stratigraphic units in the Tamworth Belt and Gunnedah Basin.
