The Upper Permian sedimentary successions of the southern Sydney Basin have been the subject of several stratigraphic, sedimentological, and petrographic studies and more recently several studies dating the sedimentary succession using U-Pb zircon and 40Ar-39Ar geochronology. In this study the Broughton Formation of the Lower Permian, part of the upper Shoalhaven Group succeeding the Talaterang Group and underneath the Illawarra Coal Measures was studied. The Broughton Formation is part of a Permian retroarc depositional basin within the Southern Sydney Basin (SSB) which is unconformable on the Lachlan Fold belt to south and west, and in tectonic contact with the New England Fold Belt to the north and east. The chronology of the Upper Permian of the SSB is well constrained. However, the chronology of the Lower Permian of the SSB, including the Broughton Formation, is less well constrained. Thus, there is debate over the timing and absolute length of several glacial and interglacial cyc
The geology that underlies highway mountain passes is a significant factor that should be considered in the construction, maintenance, and monitoring schedule of infrastructure that exists within these areas. This thesis focuses on 3D mapping of the geology beneath Mount Ousley Road, a major road corridor that links Wollongong and Sydney. This project paid particular emphasis on mapping the boundary between unconsolidated Quaternary alluvium and colluvium, and underlying geological units. The 3D model was constructed within the ArcGIS Pro and IPM-MOVE software packages. The 3D model was developed using existing geological maps, and constructing geological cross-sections that incorporated borehole logs that were digitised from hardcopy logs supplied by Transport for New South Wales (TfNSW). The model allowed for the construction of a 3D surface of the interface between Quaternary material and bedrock. Preliminary mapping was also undertaken regarding the surrounding geological units, bu
