The pocket in this Bulletin contains five Australia-wide correlation charts and location maps in microform (together with microform of the Bulletin text). The charts summarize the stratigraphy of the major Australian basins that belong to two categories in the Tectonic Map Map of Australia and New Guinea (1971) Trans- Australian Platform Cover and Central Australian Platform Cover. Several basins belonging to Transitional Domains have also been included because one of them (Adavale Basin) contains hydrocarbons. The platform cover in Australia that is Adelaidean to Recent in age can be studied in five major time-rock groupings, each of which forms the basis of one of the charts. These groupings are clearly similar to the 'megasequences' described by J. W. Porter and R. G. McRossan for the Phanerozoic of Canada and which appear to have worldwide significance and seem to conform to major events preceding and following the breakup of Pangaea (Basin consanguinity in petroleum resource estimation. In Haun, J. D. (Ed.), Studies in Geology No. I-Methods of estimating the volume of undiscovered oil and gas resources. Amer. Ass. petrol. Geol., Tulsa, 1975). An attempt has been made to show the lithology, maximum thickness and environment of deposition of the various beds listed. Estimates of hydrocarbon reserves are as quoted in BMR Petroleum Newsletter No. 62 (1975). A wide range of published stratigraphic correlations and interpretations has been used in the compilation. No rigid interpretation of age or equivalence of strata should necessarily be presumed by the layout of the data in the charts. Brief notes on the major time-rock groupings follow, together with selected bibliographies.
