Seemore, WA, 2009 (Eucla Basin 1) (P1208), 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 Seemore, WA, 2009 (Eucla Basin 1) survey were acquired in 2009 by the WA Government, and consisted of 105710 line-kilometres of data at 200m line spacing 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.

Structural and Stratigraphic Architecture of Australia's Frontier Onshore Sedimentary Basins: The Arckaringa, Officer, Amadeus and Georgina Basins

The Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data, in conjunction with state and territory geological surveys, across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Here, we present data from two seismic lines collected in South Australia and the Northern Territory. Seismic line 08GA-OM1 crossed the Arckaringa and Officer Basins in South Australia and the southernmost Amadeus Basin in the Northern Territory. Seismic line 09GA-GA1 crossed the north eastern part of the Amadeus Basin and a complete section across the southern Georgina Basin in the Northern Territory. Structural and sequence stratigraphic interpretations of the seismic lines will be presented here, eventually leading to an assessment of the petroleum potential of the basins. 
In seismic line 08GA-OM1, the Carboniferous to Permian Arckaringa Basin is imaged as series of depocentres forming the Phillipson Trough, with a much thinner succession connecting the depocentres, and extending well to the north. It is overlain by a thin cover of the Mesozoic Eromanga Basin and Cenozoic sediments. 
Seismic line 08GA-OM1 also crosses the Neoproterozoic to Devonian eastern Officer Basin. The basin is structurally complex in this area, being dominated by south-directed thrust faults and fault-related folds, providing potential for underthrust petroleum plays. The northern margin of the basin is overthrust by the Mesoproterozoic Musgrave Province. To the north, the Moorilyanna Trough is a major depocentre up to 7000 m deep.

Presentations from the GEO Week 2019 Targeted Side Event - Earth Observations: Preparing the global resource industry for a sustainable future

On 5 November 2019, Geoscience Australia presented a Targeted Side Event at the GEO Week 2019 Ministerial Summit in Canberra (http://www.earthobservations.org/geoweek19.php?t=home). GEO, the Group on Earth Observations, is a global intergovernmental partnership of 105 Member governments, 127 Participating Organizations and thousands of individuals and businesses that strives to improve the availability, access and use of Earth observations for a more sustainable planet.

The theme of the Targeted Side Event was as follows.

Strong, resilient and sustainable communities have jobs, homes, clean water, feel safe and are well connected locally, nationally and internationally. Government, business, industry and community decision makers can progress economic, social and cultural development using new, free digital information and mapping tools. Smart, fast and trusted decisions made using digital information and digital mapping can be used for any sized community, remote, rural, city, national. Sustainable development, responsible growth through a reform and transform approach can unlock new resource opportunities and respond to the economic and social challenges faced by many countries. Presented is a new digital mapping decision making tool that integrates resources: minerals, energy and water, within a social, economic and environment frame.

Addressing social licence and environmental sustainability is becoming increasingly important to ensuring the future economic development of Earth resources. The challenge for geoscientists is to create tools using data integrated from multiple disciplines to deliver insight into the complex interactions between diverse Earth systems and human society. These tools will enable specialists and non-specialists in communities, government and industry to make informed decisions for a sustainable future.

Geoscience Australia's Magnetotelluric program and data release

Geoscience Australia, in partnership with State and Territory Geological Surveys and research organisations, 
has applied the magnetotelluric (MT) method to image the resistivity structure of the Australian continent over 
the last decade. Data have been acquired at nearly 5000 stations through the collaborative national AusLAMP
survey and regional MT surveys. The data provide valuable information for multi-disciplinary interpretations 
that incorporate various datasets. Most of these MT data have been released to the public. 
To date, AusLAMP has been completed ~30% of the national coverage. Data have been acquired at nearly 
1000 stations. This pre-competitive dataset will be an essential input to Geoscience Australia’s Exploring for 
the Future program as well as a valuable resource for researchers to reconstruct the tectonic evolution of the 
Australian continent. 
The regional MT surveys have been undertaken across potential mineral/energy provinces and greenfields 
areas in the Australia continent. A number of regional surveys have been completed recently. The MT data 
from the poorly understood Southern Thomson Orogen and Coompana region have improved understanding 
of cover thickness, sub-surface geology, and crustal architecture. The data reduce the uncertainty associated 
with intersecting the targeted stratigraphy for the pre-competitive stratigraphic drilling program. Comparison 
with drill-hole information indicates that the technique is capable of identifying major stratigraphic structures 
and providing cover thickness estimates with reasonable accuracy in regions where there is little surface 
outcrop and thick cover sequences.
The MT data from the Mount Isa inlier in northern Australia provide new insights into basement architecture, 
the crustal architecture and resource potential in this region. The data reveal some crustal-scale conductivity 
anomalies which correspond to known major crustal boundaries and faults. Those faults and boundaries are 
considered the primary factors in the partitioning of mineralisation in the region, with some conductors in the 
upper crust coinciding with known mineral deposits.

Sandstone combined dose rate grid geodetic

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 Sandstone combined dose rate grid geodetic has a cell size of 0.0005 degrees (approximately 52m) and shows the terrestrial dose rate of the Sandstone-Lake Mason-Arenite merge, 1994-2000. The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 64185 line-kilometres of data at a line spacing between 200m and 400m, and 40m terrain clearance.
