Bago Maragle dose rate grid geodeticg

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Bago Maragle dose rate grid geodeticg has a cell size of 0.00042 degrees (approximately 42m) and shows the terrestrial dose rate of the Bago/Maragle State Forest, NSW, 1996. The data used to produce this grid was acquired in 1996 by the NSW Government, and consisted of 6694 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Basin-forming structures and their relevance to hydrocarbon exploration in Bass Basin, southeastern Australia

Interpretation of high-quality seismic reflection data from Bass Basin, southeastern Australia, has led to the recognition of major Early Cretaceous extensional normal faults segmented by contemporaneous transfer faults. The normal faults, which initiated development of the basin, are rotational, have low to moderate dips, and were produced by 60-80% horizontal extension (B = 1.6-2.0) of the crust beneath the basin.  There are three major normal faults, with trends of 290Â° to 300Â° - one along each margin and one near the centre of the basin. The transfer fault s are vertical and trend 0200 to 030Â°. They are predominantly of right-lateral offset, giving rise to the northwesterly trend of the basin.  The normal faults and associated tilt-block edges have had a major influence on structural evolution in the overlying hydrocarbon-prospective Eastern View Coal Measures (EVCM).  A play concept is presented that relates the mid-basin tilt-block/normal fault system and associated transfer faults to structures, facies variations, and source maturity within the EVCM. A geohistory analysis of a specific location containing such a structure associated with possible direct hydrocarbon indicators shows that the lower EVCM has been oil-mature since the Oligocene, and it is suggested, therefore, that the prospectivity of the Bass Basin should be upgraded.

Multiple-scale magnetotelluric surveys – mapping the lithosphere to the near surface for mineral systems

Magnetotellurics is one of few techniques those can provide multiple-scale datasets to understand the larger mineral system. We have used long-period data from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) as first-order reconnaissance survey to resolve large-scale lithospheric architectures for mapping areas of mineral potential in northern Australia. The 3D resistivity model reveals a broad conductivity anomaly extending from the Tennant Region to the Murphy Province, representing a potential fertile source region for mineral systems. We then undertook a higher-resolution infill magnetotellurics survey to refine the geometry of major structures, and to investigate if the deep structure is connected to the near surface by crustal-scale fluid pathways. The resistivity models reveal two prominent conductors in the resistive host whose combined responses result in the lithospheric-scale conductivity anomaly mapped in the AusLAMP model. The resistivity contrasts coincide with major structures preliminarily interpreted from seismic reflection and potential field data. Most importantly, the conductive structures extend from the lower crust to the near surface at where the major faults are located. This observation strongly suggests that these major faults are deep-penetrating structures that potentially acted as pathways for transporting metalliferous fluids to the upper crust where they could form mineral deposits. This result indicates high mineral prospectivity for iron oxide copper–gold deposits in the vicinity of these major faults. We then used high-frequency data to estimate cover thickness to assist with drill targeting for the stratigraphic drilling program which, in turn, will test the models and improve our understanding of basement geology, cover sequences and mineral potential. This study demonstrates that integration of geophysical data from multiscale surveys is an effective approach to scale reduction during mineral exploration in covered terranes.

Bluecap

Bluecap  is an open-source python software library developed through a collaboration between Monash University and Geoscience Australia. The software enables geospatial economic simulation of Australian resource projects. The simulator's goal is to highlight regions of high potential value in the early planning/exploration phase. Bluecap is designed to assist companies in focusing their efforts on regions more likely to generate commercially-viable projects. It was initially developed for the purpose of supporting mineral exploration, and has recently been expanded to include the capability to model hydrogen production.
The simulator is a pre-scoping tool that uses coarse-level empirical models to compare project prospects across large areas. Due to its broad scale, Bluecap lacks the detailed information necessary for full feasibility studies, and as such, it should not be used as the sole basis for investment decisions.
The Bluecap software underpins Geoscience Australia's Hydrogen Economic Fairways Tool (HEFT) and Economic Fairways Mapper.

AUSGeoid98 v.1.0 data files:  (sl53-01)

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.

Systematic effects in apparent proper motion of radio sources

The galactocentric rotation of the Solar system generates the systematic effect in proper motions known as 'secular aberration drift'. This tiny effect (about five microseconds per year) in the quasar proper motion can be measured by VLBI. However, the motions of relativistic jets from the active extragalactic nuclei can reach several hundred microseconds per year and mimic the proper motion of the observed radio sources. These apparent motions exceed the secular aberration drift by factor of 10-100. In this paper we search the ways to overcome the difficulties and discuss our estimates of the secular aberration drift using OCCAM software.

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - vBzz (Psusp) grid

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.
This magnetic grid has a cell size of 0.00083 degrees (approximately 88m).The data are in nanoTesla per metre (or nT/m). 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. This survey grid is essentially levelled to AWAGS. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-15 geomagnetic reference model using a data representative date and elevation representative of the survey. A further enhancement has been completed to enhance the geological interpretation of the data.
