Eucla Coast, WA, 2009 (Eucla Basin 6 offshore) (P1213), 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 Eucla Coast, WA, 2009 (Eucla Basin 6) survey were acquired in 2009 by the WA Government, and consisted of 122145 line-kilometres of data at a line spacing between 200m and 200m, and 50m 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.

Geoscience Australia's pre-competitive mineral system activities

Geoscience Australia, in collaboration with the State and Northern Territory
geological surveys and the research community, will seek to reveal the hidden
potential of Australia's buried but prospective terrains. The work will involve
the acquisition, processing, interpretation and delivery of new pre-competitive
geoscience data sets that test geological models and key indicators of mineral
resource potential in the subsurface.
The work will be directed at the four inter-related initiatives identified by the National Mineral
Exploration Strategy and the UNCOVER initiative, with particular emphasis on the first two.
These initiatives are:
1. Characterising Australia's cover
2. Investigating Australia's lithospheric architecture
3. Resolving the 4D geodynamic and metallogenic evolution of Australia
4. Characterising and detecting the distal footprints of ore deposits.

L030 seismic reflection survey in the Sydney basin, NSW, 1957

Between February and May, 1957, an experimental seismic reflection survey was made in the Sydney Basin by the Bureau of Mineral Resources to test the applicability of the method in that area and to investigate the sedimentary section. The work done at four different locations is described and the seismic results obtained are discussed in relation to the known geology. In general, the seismic method proved applicable in the Sydney Basin. The use of multiple geophone and shot-hole techniques proved desirable in some areas, notably on the Hawkesbury Sandstone. The seismic work indicated the existence of sediments up to 15,000 feet thick. Insufficient seismic work was done to prove the existence of individual structures suitable for the accumulation of oil or gas.

Probabilistic seismic hazard map of Papua New Guinea

Probabilistic seismic hazard map of Papua New Guinea, in terms of Peak Ground Acceleration, is developed for return period of 475 years. The calculations were performed for bedrock site conditions (Vs30=760 m/s). Logic-tree framework is applied to include epistemic uncertainty in seismic source as well as ground-motion modelling processes. In this regard two source models, using area source zones and smoothed seismicity, are developed. Based on available geological and seismological data, defined seismic sources are classified into 4 different tectonic environments. For each of the tectonic regimes three Ground Motion Prediction Equations are selected and used to estimate the ground motions at a grid of sites with spacing of 0.1 degree in latitude and longitude. Results show high level of hazard in the coastal areas of Huon Peninsula and New Britain/ Bougainville regions and relatively low level of hazard in the southern part of the New Guinea highlands block. In Huon Peninsula, as shown by seismic hazard disaggregation results, high level of hazard is caused by modelled frequent moderate to large earthquakes occurring at Ramu-Markham Fault zone. On the other hand in New Britain/Bougainville region, the geometry and distance to the subduction zone along New Britain Trench mainly controls the calculated level of hazard. It is also shown that estimated level of PGAs is very sensitive to the selection of GMPEs and overall the results are closer to the results from studies using more recent ground-motion models.

AUSGeoid98 v.1.0 data files:  (sc52-12)

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.

L215 Adavale Basin 2D Seismic Survey

The Australian Government's Data Driven Discoveries program, in collaboration with the Geological Survey of Queensland, has collected 1715 km of deep crustal seismic data across the Adavale Basin in South-Central Queensland. The L215 Adavale Basin Deep Crustal Seismic Survey was conducted between April and July 2023. The survey acquired 7 regional seismic lines, including 23GA-A1 (550 km), 23GA-A2 (196 km), 23GA-A3 (262 km), 23GA-A4 (94 km), 23GA-A5 (239 km), 23GA-A6 (161 km), and 23GA-A7 (213 km) across the basin. The acquisition of these lines occurred both during the day and night near the towns of Adavale, Charleville, Augathella, Blackall, westward towards Windorah, and north beyond Jericho.

The Adavale Basin Deep Crustal Seismic Survey complements previous work completed under the Data Driven Discoveries Program, including the Adavale Basin 2D Reprocessed Seismic Data Package (eCat No. 149018) and the newly defined chemostratigraphic framework for the basin (Riley et al., 2023, eCat No. 147773). The survey will deliver a significant uplift in regional shallow and deep crustal seismic information for the Adavale Basin, providing a modern, high-fold dataset that will enhance understanding of the basin's stratigraphy, hydrogeology, resource potential, and underground salt storage opportunities.

The processed stacks are available to download directly using the links provided below. Please download both parts (001 and 002) of the zip package into the same folder and use a zip program to unzip part 001—part 002 will be extracted automatically.

The raw shot gather data acquired during the survey are now available from Geoscience Australia. To request this data, please email clientservices@ga.gov.au and include the reference 'eCat#149289' in your message.

Resistivity model derived from magnetotellurics: AusLAMP-TISA project

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) aims to collect long period magnetotelluric data on a half degree (~55 km) grid across the Australian continent. New datasets have been collected in Northern Australia, as part of Geoscience Australia’s Exploring for the Future (EFTF) program with in-kind contributions from the Northern Territory Geological Survey and the Queensland Geological Survey. 

This release includes preliminary AusLAMP models in an under-explored region between Tennant Creek in the Northern Territory and Cloncurry in Queensland. Long period magnetotelluric data from 155 sites were used in this model. Magnetotelluric data acquisition in this region continues. The preliminary model results provide new insights to the lithospheric architecture and mineralisation in the region. There is a connection between conductive anomalies, large-scale lithospheric boundaries and the distribution of mineral deposits.
