Light Hydrocarbon Geochemistry in Bottom-waters of the Arafura Sea, Northern Australia : Project 121.24

During February-March 1990 the BMR conducted a combined seismic and DHD
(Direct Hydrocarbon Detection) survey in the Arafura Sea of northern Australia. This
survey was the second to employ the 'geochemical sniffer' (DHD) aboard Rig Seismic,
and represented the first deployments of the geochemical equipment from amidships
Rig Seismic. The purpose of these deployments were to develop the capability to
collect underway, bottom-water geochemical data simultaneously with seismic
reflection, gravity and magnetic data. The bottom-water geochemical data hence
would complement existing remote sensed methods to aid in offshore exploration for
hydrocarbons, and to provide new insights into concepts of hydrocarbon generation
and migration. As such, the deployment of the equipment amidships Rig Seismic was
successful and will become a permanent installation. However, some mechanical
(deployment) and data collection difficulties resulted in some gaps and artefacts in the
bottom-water DHD, and these are noted in the text. Some parts of the data have been
heavily edited.

Depth to basement 3D model in the South-Nicholson Basin, Northern Australia

To help the management and exploration at depth of increasing demand for mineral, energy and water resources, integration of new data acquired in frontier areas in a common 3D sub-surface geological model is critical. The Exploring for the Future Program has facilitated the acquisition of major datasets in northern Australia, where rocks are mostly undercover and the basin evolution and resource potential is not well understood. 
Here we present a case study in the South-Nicholson Basin, located in a vast, poorly exposed area between two highly prospective Paleo- to Mesoproterozoic provinces, the Mt Isa Province and the McArthur Basin. Both regions host major base metal mineral deposits, and contain units prospective for hydrocarbons. In this study we integrate new large-scale data, which include ~1 900 km of deep seismic reflection data and 60 000 line kilometers of AusAEM1 airborne electromagnetic survey, with legacy information and new tools, to help build a semi-continental geological framework, as input to national coverage databases and inform decision-making for mining and petroleum exploration. 
This study provides a 3D chronostratigraphic cover model down to the Paleoproterozoic basement. We mapped the depth to the base of geological eras, as well as deeper pre-Neoproterozoic Superbasin sequence boundaries to refine the cover model. The depth estimates are based on the interpretation, compilation and integration of boreholes, solid geology, reflection seismic, airborne electromagnetic data and depth to magnetic source estimates. These depth estimates are consistently stored in national databases. These integrated datasets inform on the basin evolution in relation to the basement architecture and provided key outcomes: 1) expanded the size of the basin, significantly increasing the extent of regional petroleum systems in the region, 2) revealed a large concealed sedimentary sub-basin interpreted to include rocks that host the world class Mount Isa Cu-Pb-Zn deposits, 3) linked the stratigraphy with correlation of prospective stratigraphic units across the region, 4) identified major crustal boundaries and structures showing evidence for crustal-scale fluid flow and localised groundwater springs.

Lake Eyre - K equivalent concentration grid (AWAGS, nasvd)

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 potassium grid has a cell size of 0.0004 degrees (approximately 41m) and shows potassium element concentration of the Lake Eyre Airborne Magnetic Radiometric and DEM survey, SA, 2017 in units of percent (or %). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 92215 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

AUSGeoid98 v.1.0 data files: Alcoota (sf53-10)

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.

SA Exploration Initiative 1994 - Area B12 and B13 (P711), 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 SA Exploration Initiative 1994 - Area B12 &amp; B13 survey were acquired in 1994 by the SA Government, and consisted of 14201 line-kilometres of data at a line spacing between 200m and 200m, and 90m 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.

Hypocentre relocations using data from temporary seismograph stations at Burakin and Wyalkatchem, Western Australia

Temporary seismograph stations were operated near Cadoux W.A. after a large (ML 6.2) earthquake on 2 June 1979 near Wyalkatchem WA, after an ML 4.3 event near there 6 January 1988. The earthquake near Wyalkatchem was the largest of a series of events at this locality which continued over a period of 15 months. Arrival times recorded by these stations are tabulated in this paper. They have been used to relocate some of the 1979 Cadoux aftershocks using the Phillip Institute of Technology EQLOCL earthquake location program. The effect of the relocations has been to move the epicentres from east of the fault complex, to west of it. This result is similar to the distribution of some accurately located 1983 earthquakes, and is consistant with the mapped fault dip. Relocations using data from the Wyalkatchem station have not resulted in a significant change in hypocentral parameters. Consistent large residuals for NWAO S phases from Cadoux events indicate the first S arrival is not SN, and is more likely to be SG.
