AUSGeoid98 v.1.0 data files:  (sk50-01)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

The potential for CO2 storage in residual oil zones in onshore Australian basins

We have investigated whether water-saturated residual oil zones (ROZs), sometimes associated with conventional Australian hydrocarbon plays, could provide a CO2 storage resource and supplement depleted field storage. 

Our petrophysical study demonstrates that ROZs occur in Australia’s hydrocarbon-rich regions, particularly in the Cooper-Eromanga Basin. ROZs with more than 10% residual oil saturation are uncommon, likely due to small original oil columns and lower residual saturations retained in sandstone reservoirs than in classic, carbonate-hosted North American ROZs. Extensive, reservoir-quality rock is found below the deepest occurring conventional oil in many of the fields in the Eromanga Basin, potentially offering significant CO2 storage capacity.

Multiphase compositional flow modelling was used to estimate the CO2 storage efficiency of typical Australian ROZs. We developed a novel modelling methodology that first captures oil migration events leading to the formation of ROZs. Modelling CO2 storage over a 20-year injection period demonstrates that CO2-oil interactions increase the density and viscosity of CO2, enhancing CO2 sweep efficiency and lateral flow, improving storage efficiency. The extent of these effects depends on the quantity and spatial distribution of residual oil in place and the miscibility of CO2 at reservoir conditions.

Uranium mineralisation events in Australia: geochronology of the Nolans Bore, Oasis, Kintyre, Mt Gee-Armchair and Maureen uranium deposits

This report presents new geochronological results for five uranium deposits in Australia, detailing the timing of uranium mineralisation in relation to regional geological events.  The purpose of the study is to better constrain ore genetic and exploration models for these uranium mineral systems, and ultimately to improve understanding of the uranium resource potential of the Australian continent.  The work was carried out under the auspices of the Onshore Energy Security Program.
Each of the five uranium deposits represents a different style of mineralisation within three broad families of uranium mineral systems: magmatic-related, basin-related, and metamorphic-related.  The results contribute to the current paucity of age data for uranium deposits in Australia, and for most of the deposits the new dates are the first reported direct ages for mineralisation or associated alteration.

Evidence for former evaporites in the Carboniferous Moogooree Limestone, Carnarvon Basin, Western Australia

The former presence of evaporites within skeletal carbonate lithofacies of the Moogooree Limestone, Carnarvon Basin, is inferred from the presence of quartz geodes which have formed by the replacement of early diagenetic anhydrite nodules, and patchy dedolomitisation of much of the sequence.

Coompana, SA, 2015 (P1270), radiometric line data

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 Coompana, SA, 2015 (P1270), radiometric line data were acquired in 2015 by the SA Government, and consisted of 286817 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Optical spectra of southern flat-spectrum IVS radio sources

About 1200 radio quasars are observed regularly by the International VLBI Service, IVS, to define and maintain the International Celestial Reference Frame, ICRF. We have presented evidence for large scale systematic proper motions, dipole and quadrupole effects, at a level in excess of 10 µas/year. This result presents a serious
challenge to the standard cosmologies.  However, we have a concern that our estimates of the spherical harmonics may be influenced by the paucity of IVS quasars with known redshifts in the south. We estimate that 100--150 new redshifts uniformly distributed in the south will remove these concerns. In this paper the results of spectroscopic observations of 43 southern radio sources with 3.58-meter NTT telescope are presented.

Summary of results. Re–Os molybdenite dating from the Hit or Miss deposit, Hatches Creek tungsten field, Warramunga Province

This Record details rhenium–osmium (Re–Os) dating of molybdenite separated from quartz veins associated with tungsten mineralisation at the Hit or Miss deposit of the Hatches Creek tungsten field, Warramunga Province. Two samples of molybdenite were collected from the former mine: sample FR17MVM001 as drill chips from a tungsten-mineralised quartz vein in drillhole HCRC021, and sample FR17MVM002 from a quartz vein in surface workings associated with tungsten and molybdenum. Molybdenite was dated to determine an absolute age for tungsten mineralisation at the deposit. The Re–Os molybdenite model ages obtained were 1677 ± 10 Ma and 1602 ± 9 Ma respectively. These ages are tentatively interpreted as mineralisation and/or remobilisation ages for molybdenum and tungsten, and the associated bismuth and copper at the Hit or Miss deposit; they also provide timing constraints on mineralisation in the wider Hatches Creek tungsten field. Low Re concentrations in the samples (1–2 ppm) are consistent with an evolved crustal source for the tungsten
mineralisation. 
The older of the two Re–Os model ages is broadly consistent with previous age determinations for tungsten mineralisation and felsic intrusions in the Warramunga Province using Ar–Ar muscovite and U–Pb zircon dating methods. Although the geological significance of the new Re–Os molybdenite age is uncertain, the results are tentatively interpreted to record a protracted episode of tungsten, copper and molybdenum mineralisation in the Warramunga Province between ca 1700 –1600 Ma, associated with evolved felsic intrusions.

Incorporating fault sources into the Australian National Seismic Hazard Assessment (NSHA) 2018

Unique challenges are faced in modelling faults in intraplate regions for seismic hazard purposes.  Low fault slip rates compared to landscape modification rates lead to often poor discoverability of fault sources, and favours incomplete characterisation of rupture behaviours.  Irrespective, regional and local test cases have demonstrated that fault sources assigned activity rates consistent with paleoseismic observations have the potential to significantly impact probabilistic seismic hazard assessments in Australia.  To reflect this, the 2018 Australian NSHA will for the first time incorporate a fault source model. The model includes over 300 onshore faults, and a handful of offshore faults, which are modelled as simplified planes and assigned a general dip and dip direction.  Dips are obtained from seismic-reflection profiles, where available, or inferred by taking into account surface geology and geomorphology, or other fault geometries within similar neotectonic settings.  The base of faulting is generally taken as the regional maximum depth of distributed seismicity.  Slip rates are calculated from displaced strata of known age, estimated from surface expression, or are extrapolated from other faults within similar neotectonic settings.  We construct logic trees to capture epistemic uncertainty in fault source parameters, including magnitude frequency distribution, and the potential for random, periodic or episodic recurrence behaviour.  This presentation introduces the new fault source database, the fault source logic tree as it currently exists, and discusses uncertainty in and sensitivity to various elements of the proposed fault source input model.
