Bedrock units range in age from Early Ordovician to late Tertiary (mid-Miocene). About 80% of the map sheet area is covered by Cainozoic units. The use of high quality geophysical datasets is invaluable in interpreting the geology. {"type": "Polygon", "coordinates": [[[147.0, -34.0], [148.5, -34.0], [148.5, -33.0], [147.0, -33.0], [147.0, -34.0]]]} 147.0 148.5 -34.0 -33.0 AU-NSW Earth Sciences GA Publication Published_External Record geology Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
