Stratigraphy of Special Areas
The Devonian System of New England, New South Wales, Australia
Abstract
The Devonian sequence of New England, Australia is essentially eugeosynclinal, the predominant rock types being pelagic or turbidite sediments of andesitic provenance. Interspersed limestones contain 8 or 9 coral and conodont faunas of early Gedinnian, late Emsian, Eifelian and Givetian ages. Famennian ammonoids and conodonts, indicative of the Cheiloceras, Platyclymenia and Wocklumeria Stufen, are known from higher in the succession. There is no faunal evidence for the presence of either Siegenian or Frasnian beds, although part of the Baldwin Formation is assumed to be of the latter age. Two unconformities have been recognised in the Upper Devonian and it is possible that another unconformity (or disconformity) separates the Gedinnian and Emsian parts of the sequence.
