AusLAMP - mapping lithospheric architecture and mineral potential in central and eastern Australia

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative national survey between federal government, state/territory governments and research organisations. The project aims to acquire long-period magnetotelluric (MT) data at half-degree spacing (~55&nbsp;km) across the Australian continent. AusLAMP started in 2013 and has completed about 1500 stations (~50% of total planned stations) to date. Over the last decade, regional-scale AusLAMP resistivity/conductivity models have been produced following data acquisition campaigns, but there is a strong demand for a single model. We produced a resistivity model from 1260 AusLAMP stations incorporating 85% of data acquired to date. The new AusLAMP resistivity model shows significant variations of resistivity at varying depths from a few kilometres to a couple of hundred kilometres in the crust and upper mantle. The model resolves the first-order resistivity structure of the Australian lithosphere across most parts of central and eastern Australia, including Tasmania. The resolved resistivity structures allow seamless interpretation across states and regions, broadly conform with identified major geological domains and crustal boundaries, and reveal significant variations within geological provinces, orogens and cratons. There are also strong spatial associations between crustal/mantle conductors and copper and gold deposits and carbonatites, which provide further evidence that major lithospheric conductors control the distributions of a range of mineral systems. This evidence aligns well with the conceptual model of mineral systems, that convecting mantle fluid and metal-rich magma can migrate into the crust through weak zones to form some ore deposits in the lithosphere. This new AusLAMP model demonstrates that long-period MT data are an important first-order reconnaissance dataset to resolve large-scale lithospheric architecture and provides a powerful tool with a bottom-up approach to highlight potential exploration areas, particularly in covered and under-explored regions.

Cloudy with a chance of noise

One annoying geodetic variable is a treasure trove of information to meteorologists. This talk will focus on a project in partnership with the BoM, RMIT and FrontierSI turned our estimates of the tropospheric delay in our GPS analysis into useful information for weather forecasting systems. The system works by measuring the time it takes GPS signals from satellites to reach ground receivers. Signals can be slightly delayed by moisture in the troposphere, causing what's known as a zenith total delay, so scientists measure this delay to assess air moisture
While the technology could be applied almost anywhere, it is particularly valuable in a sparsely populated country like Australia where there is a lack of ground-based meteorological observation stations.
Atmospheric water vapour is highly variable and non-linear in nature, yet it is important for accurate weather forecasting of storms. Having a direct observation from GPS provides an exciting opportunity for near and real-time weather forecasting systems.

Chemostratigraphy of the Sherbrook Supersequence – 13 wells from the offshore Otway Basin

An elemental chemostratigraphic study of the offshore Otway basin has been undertaken as part of a collaboration between Chemostrat and Geoscience Australia (GA). The main aim of which is to better constrain the sequence boundaries of, and within, the Sherbrook Supersequence. This comprehensive study includes the elemental analysis of 1185 cuttings samples from the Sherbrook Supersequence (and overlying stratigraphy) in 13 wells, located offshore Otway Basin. Sampling of cuttings for this project was particularly challenging as many of the targeted wells have a paucity of material available for destructive analysis. Lithological and well log interpretation in the basin is often inadequate for constraint of sequence boundaries. Nonetheless the use of Inductively Coupled Plasma-Optical Emission Spectrometry and Mass Spectrometry (ICP-OES and MS) analysis was undertaken to complete a regional elemental chemostratigraphic study of the Sherbrook Supersequence, Otway Basin. The resultant chemostratigraphic framework, with nomenclature adapted from Forbes et al (2020) comprises of two chemostratigraphic sequences, eight chemostratigraphic packages and seventeen chemostratigraphic units. It is important to note that in some wells the chemostratigraphic correlation differs extensively from the lithostratigraphy, highlighting areas for closer examination. From the 13 wells analysed at least three, Crayfish-1A, Copa-1 and Breaksea Reef-1, indicate necessary changes to markers for LC2 (base Sherbrook). Additionally, within the Sherbrook Supersequence, there is scope for correlation between wells despite their separation, and seismic ties can now be better constrained.

Ordian (Cambrian) Crustacea Bradoriida of Australia

The fauna of the 'Redlichia-bearing beds' of Northern Australia, except for the occurrence of the trilobite Redlichia and the shells of Biconulites, is largely undescribed; a part of the hitherto neglected components of that fauna is the Crustacea Bradoriida, which are now described here. For the sake of a taxonomic description the need arose forEleven species of Bradoriida are described, with open nomenclature applied to two forms; the family Bradoriidae is represented by four new species of Bradoria, the Indianidae by lndota otica gen. nov., sp. nov., and Tropidiana cirrata gen. nov., sp. nov., and the new family Comptalutidae by Comptaluta gen. novo and Ophiosema gen. novo The Comptalutidae contain also some of the species described in the literature under the name of A luta. The names lndianites and Indianitidae are regarded as nomina nuda. and Aluta and Alutidae as having no recognizable material base. The Hipponicharionidae are regarded as a subjective synonym of the Beyrichonidae. The new family Svealutidae is established for forms which cannot be accommodated in any of the already established families; these forms are Svealuta, Carnarvonia, and A lutella, and not part of the taxa described here. The described species come from the Yelvertoft Beds of Queensland; their age is Ordian, the Cambrian Stage below the Templetonian and above the Lower Cambrian (Georgian), and an equivalent of the 'Protolenus zone' of authors and the Hanfordian of Matthew. Corrections are also suggested to the obsolete data of the stratigraphic distribution of Bradoriida that are prevalent in the current literature. The neozoological and palaeozoological affinities are discussed, and classifications of Crustacea pertaining to the order Bradoriida reviewed. The Bradoriida are not acceptable as an order of Ostracoda, but the structure of their carapace suggests an affinity with the contemporaneous Canadaspis.

GSWA Yalgoo uranium Grid Geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 radiometric uranium grid has a cell size of 0.00021 degrees (approximately 22m) and shows uranium element concentration of the Yalgoo, WA, 2014 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2015 by the WA Government, and consisted of 126967 line-kilometres of data at a line spacing between 100m and 200m, and 50m terrain clearance.

Canberra International Map of the World (IMW) 1:1 000 000 topographic map

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

AUSGeoid98 v.1.0 data files:  (si53-15)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.
