GSNSW Exploration NSW Area F Brewarrina magnetic rtp grid geodetic

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 0.00048 degrees (approximately 50m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 51199 line-kilometres of data at 250m line spacing and 60m terrain clearance. 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-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

Petroleum prospectivity and CO2 storage assessment in the offshore Browse Basin, North West Shelf, WA/AC

Under the National CO2 Infrastructure Plan (NCIP) and the National Low Emissions Coal Initiative (NLECI), Geoscience Australia undertook multi-purpose basin analysis to address dual priorities to assess long-term CO2 storage potential while simultaneously provides new insights into hydrocarbon prospectivity. The Browse Basin assessment is part of this five year program and provides better understanding of basin-scale storage potential and new insights into hydrocarbon prospectivity to manage the potential resource conflicts. 
The Browse Basin is a northeast-trending Paleozoic to Cenozoic depocentre situated offshore on Australia's North West Shelf and is being actively explored for hydrocarbons. It hosts large undeveloped gas and condensate accumulations, and is soon to become Australia's next major conventional liquefied natural gas (LNG) province. The basin was identified as potentially suitable for offshore geological storage of CO2 due to its favourable geological setting on a passive margin, and its proximity to offshore gas resources that can contain high amounts of naturally occurring CO2. 
The multi-purpose basin approach in the Browse Basin included the acquisition and integration of pre-competitive data derived from an airborne magnetic survey, two marine surveys, and the geochemical analysis of oils, gases and rocks, provided by industry through the Offshore Petroleum Titles Administrator (NOPTA)-managed repository. All of this precompetitive data had applications towards, and addressed questions relevant, to the assessment of both CO2 storage potential and hydrocarbon prospectivity. 
The concurrent basin analysis research provided a new understanding of the basin's Cretaceous succession based on an integrated sequence stratigraphic analysis of 60 wells and an extensive set of industry and government 2D and 3D seismic reflection data. The basin's tectonostratigraphic framework was updated, and the integration of revised biostratigraphic data enabled an improved understanding of variations in depositional facies and the spatial distribution of reservoir, seal, and source rock (condensed) sections. The outputs include models and maps of environments of deposition, petroleum systems and play fairways. 
Consequently, prospective CO2 storage sites throughout the succession were identified in areas that were least likely to conflict with hydrocarbon exploration. Results from this pre-competitive project will improve future storage site selection in suitable reservoirs for the commercial deployment of CCS technology, and will promote new hydrocarbon exploration opportunities.

Crustal structure of the central Bowen Basin, Queensland

During May-June 1973, a deep crustal seismic refraction survey was undertaken in the Bowen Basin, Queensland. Blasts from open-cut coal mines in the Basin were used as sources of seismic energy, and recordings were made at twenty-two sites on a 375 km-long line along the axis of the Basin between Goonyella in the north and Moura in the south. A four-layer crust was interpreted from the seismic data, with P-wave velocities of 4.00 Â± .22, 5.33 Â± .08, 6.39 Â± .07 and 7.07 Â± .02 km/ s respectively. The total thickness of the 4.00 and 5.53 km/s layers is about 6 km under Goonyella, and slightly more under Dingo 130 km north of Moura. Earlier magnetic and gravity work indicates that these two layers thin southwards towards Moura. They comprise folded Permian-Triassic sediments and possibly also Early to Middle Palaeozoic rocks. The 6.39 km/s layer probably represents the igneous or granitised basement. A lower crustal layer with a velocity of 7.07 km/s and thickness ranging between 5 and 6 km has been interpreted. The total crustal thickness at the centre of the traverse is 36 km, and the upper mantle P-wave velocity is 8.10 Â± .11 km/s. A southward-dipping Moho may be interpreted, with the crustal thickness increasing from 35 km, 30 km south of Peak Downs, to 37 km near Dingo. The gravity field calculated from the model conflicts with the observed gravity, suggesting a more complex model than that defined by the seismic refraction data alone.

Volcanic-tsunami hazard assessment - A case study from Heard Island and McDonald Islands, Australia

Volcanic-tsunami can occur with little warning, travel quickly (up to 1000km/hr) and cover great distances causing devastating impacts. There are several mechanisms for volcanic-tsunami events, including underwater explosion, blasts, pyroclastic flows, caldera collapse, subaerial failure and submarine failure. For the latter two, volcanic activity is not a pre-requisite, which presents additional challenges when raising awareness and undertaking planning activities.
Volcanic-tsunami are often not considered in hazard and risk assessments, particularly as a far-field source. This can leave communities vulnerable to their impacts. It is estimated that 20-25% of fatalities directly attributable to volcanoes in the last 200-250 years have resulted from volcanic-tsunami (Latter, 1981; Auker et al., 2013) (e.g. ~36,000 deaths were a direct result of the tsunami generated from the 1883 Krakatau eruption). Moreover, volcanic-tsunami account for ~6% of tsunami events globally and can generate tsunami with a similar intensity to those from earthquake sources. In volcanically active regions the possibility of experiencing impacts from volcanic-tsunami is likely to be greater, highlighting a need for inclusion in hazard assessments.
A volcanic hazard assessment that includes volcanic-tsunami can be as fundamental as an identification and characterisation of potential source volcanoes. More in-depth hazard assessments can then be produced through numerical modelling of propagation and inundation from tsunami generated in volcanic regions. In combination, this can provide an evidence base for undertaking more extensive analysis, or to provide guidance to planners who wish to consider potential impacts from lower frequency/higher consequence events.
Here we present a method for classifying volcanoes for their potential to generate a tsunami and demonstrate the application of this method to the Heard Island and McDonald Islands (HIMI). HIMI are Australian Antarctic Territories located ~4000 km south west of Perth, Australia. Both of these eruptive centres have experienced violent, ongoing eruptive events; Heard Island as recently as 2016. Our analysis indicates that there is the potential for submarine mass failure at HIMI which could feasibly generate a tsunami detectable along the south-west Australian coast and in Antarctica. This poses a potential tsunami hazard to Australia, but more work needs to be undertaken to understand the mechanism and likelihood of such events.
