Abstract
An investigation of spore-pollen assemblages from the Permian succession of the Stroud-Gloucester Trough, N.S.W., establishes that sedimentation began at the top of palynological zone Upper Stage 4 in the Dewrang Group. Deposition continued, without major break, through to the Gloucester Coal Measures, which are of lower Upper Stage 5 age. Sediments from within the underlying Alum Mountain Volcanics have a Stage 3a age.
