The Lower Permian Wasp Head Formation, Sydney Basin: High-latitude, shallow marine sedimentation following the late Asselian to early Sakmarian glacial event in eastern Australia. The Lower Permian Snapper Point Formation at its type locality in the southern Sydney Basin is interpreted as a regressive sequence of a linear clastic shoreline. Lithologies, sedimentary structures, and palaeocurrent patterns suggest a prograding barrier‐beach by: Key words: Biomarkers, Permian, Sydney Basin, depositional environment, maturity. INTRODUCTION Early to late Permian sediments deposited during the Gondwanan ice age are exposed on the coast between Nowra and Batemans Bay in the southern part of the Sydney Basin, NSW, Australia (Herbert and Helby, ). Permian fossils and palaeoenvironments of the northern Sydney Basin, New South Wales. Three invertebrate fossil sites (one newly discovered) of early and middle Permian age in the Sydney Basin of New South Wales provide an insight into changing depositional environments that were dominated by marine glaciogenic conditions.
Petrographical examinations of sediments from vertical sections of the Permian Newcastle and Illawarra coal measures of the Sydney basin have been made in an attempt to Cited by: The study area is located in the southern part of the Sydney Basin, which is a part of the Bowen-Gunnedah-Sydney Basin System, a roughly north-south trending, elongate sedimentary trough situated between the New England Fold Belt and the Australian Craton (Fig. 1A).Cited by: 1. Post-Triassic sedimentation and structures. Since uplift of the basin in the Triassic, up to m of sediment has been deposited on parts of the continental shelf north of Sydney. Significant thicknesses of sediment (up to 80 m) have accumulated in coastal depressions such as Botany Bay . Sydney itself is situated on Triassic rocks and it is only towards the edge of the basin at Wollongong, Newcastle and Lithgow that the older Permian rocks come to the surface. Permian Fossils The Permian rocks in the Sydney Basin contain two different and generally isolated groups of fossils.
An integrated study of sedimentological, sequence-stratigraphic and palaeodispersal analysis was applied to the Upper-Permian clastic sedimentary succession in the Northern Sydney Basin, Australia. The succession is subdivided into fifteen facies and three facies associations. sector of the Sydney-Bowen Basin) suggest that the sediment dispersal responsible lbr the basin- fill was that of two temporally separate longitudi- nal fluvial systems. This paper examines in detail the waning stage of the first longitudinal system and the development of the second system in the Sydney Basin. depositional conditions over the boundary in terrestrial settings. The Sydney Basin contains well preserved sediments across the boundary, including the stratigraphically highest Permian coals, which get replaced by monotonous Triassic mudstones. Initial work on boreholes in the Wyong and Bulli areas have shown significant changes in biomarkers. The sediment dispersal pattern and tectonic context of the northeastern Sydney Basin at the close of deposition of the Late Permian NCM is strikingly similar to that of the northern Appalachian Basin at the onset of deposition of the Late Carboniferous coal measures (Fig in the Appalachian Basin of Pennsylvania, erosion has confined basinwide palaeocurrent study to the Pottsville Forma- Cited by:
