Stratigraphy, structure and mineralisation of the Mudgee 1:100Â 000 geological map sheet

The Mudgee 1:100 000 map sheet (8832) occupies the south-east corner of the six 1:100 000 map sheet which comprise the Dubbo 1:250 000 geological map sheet. Some of the original mapping and compilation of the Dubbo geological map sheet by Offenberg et al (1971) - and a minor update by Mason (1973) - the area has been the subject of considerable university thesis work, most notably by students of the University of New South Wales in the 1970s and the University of Wollongong in the 1970s to 1990s. The map sheet area has a range of mineral occurrences and has attracted considerable exploration activity, yielding additional geological data. Mapping and compilation of the Mudgee 1:100 000 map sheet area took place between January and July 1995 and was a joint undertaking by the Geological Survey of New South Wales and the Australian Geological Survey Organisation (AGSO) as part of the National Geoscience Mapping Accord. The project also involved significant collaboration with the staff of the School of Geosciences at the University of Wollongong who have considerable experience in the Mudgee-Cudgegong district. Mapping was greatly asissted by airborne radiometric and magnetic data collected at 400m flight line spacing across the area by AGSO in 1991. A programme of SHRIMP zircon dating of the rocks was undertaken in an effort to establish a better chronological framework for the stratigraphy (Fanning, in prep). The new map (Colquhoun et al 1996b) represents the first thorough synthesis of this comparitively poorly known area of the Lachlan Fold Belt and differs markedly from the Mudgee portion of the original Dubbo geological map sheet. This paper expands on findings which were summarised in Colquhoun et al (1996a) and aims to detail the stratigraphy and structure of the Mudgee 1:100 000 map sheet area and the implications for mineralisation.

North Western Victoria Gravity (P195609), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This North Western Victoria Gravity (P195609) contains a total of 192 point data values acquired at a spacing between 5000 and 10000 metres. The data is located in VIC and were acquired in 1956, under project No. 195609 for Bureau of Mineral Resources (BMR).

Tallangatta, Vic, 1994/95 VIMP Survey (GSV3022) (P653), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Tallangatta, Vic, 1994/95 VIMP Survey (GSV3022) survey were acquired in 1994 by the VIC Government, and consisted of 52397 line-kilometres of data at 200m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Surface-wave magnitudes of some early Australian earthquakes

Surface-wave magnitudes (Ms) of 35 of the larger Australian earthquakes that occurred before 1960 have been determined from seismograms written at Riverview (Sydney), Melbourne, Adelaide, and Perth. Magnitudes were computed by the methods of Nuttli (1973) and Marshall and Basham (1973) and found to be consistent.  Empirical corrections were applied to the horizontal component recordings to bring them into  agreement with vertical component amplitudes, implicit in the definition of the Ms scale. Richter magnitudes (ML) were plotted against the adopted (average) surface-wave magnitudes for 19  earthquakes for which ML values were available. However, the scatter of the data precludes the adoption of a definitive relation for MS on ML for the Australian continent.

FK200930 Northern Great Barrier Reef Bathymetry Acquisition (20200014S)

This resource includes bathymetry data acquired during the Northern Depths of the Great Barrier Reef survey on RV Falkor using its Kongsberg EM302 multibeam sonar system. The EM710 data acquired on this survey will be included in a future release.
The primary objective of the survey was to explore the Cape York Peninsula region, through geophysical mapping of the shelf edge and continental slope adjacent to the barrier reefs and around the seven detached reefs lying north of Cape Weymouth, including within the large Wreck Bay. The offshore Cape York area is considered a frontier marine region with very little multibeam data collected previously in this far northern section of the Great Barrier Reef. The survey aimed to reveal the full inventory of submarine canyons, drowned reefs and any other significant seabed features in the region.
A secondary objective was to conduct geophysical mapping of the Swain slide, an underwater landslide on the slope adjacent to the Swain Reefs in the southern Great Barrier Reef, with a headscarp about 10 km wide and a debris field extending ~20 km from the headscarp. The mapping aimed to reveal the full extent of the debris field and nature of the debris material proximal to the headscarp.
Another objective was to conduct geophysical mapping around the steeper slopes around reefs in the eastern Coral Sea Marine Park, including the Saumarez, Frederick, Kenn, Wreck and Cato Reefs. The mapping aimed to fill data gaps between existing airborne LIDAR bathymetry over the shallow reefs and previously collected multibeam data around the steeper flanks.
To achieve these objectives, the survey extended over 47 days, leaving Brisbane, Australia on September 30, 2020 and returning to Brisbane, Australia on November 17, 2020. The voyage was split into three legs, with port calls made at Cairns and Horn Island in the Torres Strait.
Geophysical mapping involved the use of both Kongsberg EM302 and EM710 multibeam systems on the RV Falkor, typically operated in Dual Swath mode. In depths deeper than ~1200 m, the EM710 was turned off. Backscatter and water column data were also collected on both multibeam systems.
This dataset contains fifteen 4m, 9, 10, 16 and 32m resolution 32-bit geotiff files of the FK200930 survey area produced from the processed EM302 only bathymetry data.
This dataset is not to be used for navigational purposes.
This dataset is published with the permission of the CEO, Geoscience Australia.

Open Source Flood Simulation with a 2D Discontinuous Elevation Hydrodynamic Model

A new finite volume algorithm to solve the two dimensional shallow water equations on an unstructured
triangular mesh has been implemented in the open source ANUGA software, which is jointly developed
by the Australian National University and Geoscience Australia. The algorithm supports discontinuouselevation,
or `jumps in the bed profile between neighbouring cells. This has a number of benefits compared
with previously implemented continuous-elevation approaches. Firstly it can preserve stationary states at wetdry
fronts without using any mesh porosity type treatment. It can also simulate very shallow frictionally
dominated flow down sloping topography, as typically occurs in direct-rainfall flood models. In the latter situation,
mesh porosity type treatments lead to artificial storage of mass in cells and associated mass conservation
issues, whereas continuous-elevation approaches with good performance on shallow frictionally dominated
flows tend to have difficulties preserving stationary states near wet-dry fronts. The discontinuous-elevation
approach shows good performance in both situations, and mass is conserved to a very high degree, consistent
with floating point error.
A further benefit of the discontinuous-elevation approach, when combined with an unstructured mesh, is that
the model can sharply resolve rapid changes in the topography associated with e.g. narrow prismatic drainage
channels, or buildings, without the computational expense of a very fine mesh. The boundaries between such
features can be embedded in the mesh using break-lines, and the user can optionally specify that different
elevation datasets are used to set the elevation within different parts of the mesh (e.g. often it is convenient to
use a raster DEM in terrestrial areas, and surveyed channel bed points in rivers).
The discontinuous elevation approach also supports a simple and computationally efficient treatment of river
walls. These are arbitrarily narrow walls between cells, higher than the topography on either side, where
the flow is controlled by a weir equation and optionally transitions back to the shallow water solution for
sufficiently submerged flows. This allows modelling of levees or lateral weirs much finer than the mesh size.
A number of benchmark tests are presented illustrating these features of the algorithm. All these features
of the model can be run in serial or parallel, on clusters or shared memory machines, with good efficiency
improvements on 10s-100s of cores depending on the number of mesh triangles and other case-specific details
