NTGS North Wiso Gravity P201580 Spherical Cap Bouguer Anomaly 267GU 1VD

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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. 
This NTGS North Wiso Gravity P201580 Spherical Cap Bouguer Anomaly 267GU 1VD is the first vertical derivative of the spheical cap Bouguer anomaly grid for the NTGS Northern Wiso Basin Gravity Survey (P201580). This gravity survey was acquired under the project No. 201580 for the geological survey of NT. The grid has a cell size of 0.00738 degrees (approximately 800m). A total of 4990 gravity stations at 4000m spacing were acquired to produce this grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Australian open access MT - AusLAMP and beyond

Australia boasts a world-class resource of publicly available magnetotelluric (MT) data. Its backbone is the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) – a grid of long-period deployments spaced at ~55 km designed to image the lithospheric-scale electrical structure of the continent. Since being launched in late 2013, data have been recorded at over 1500 stations, covering approximately 50% of the Australian landmass. In addition to AusLAMP are numerous targeted, smaller-scale surveys, including profiles coincident with active seismic lines, and dense grids of broadband MT stations in regions of special interest, such as those with significant mineralisation.

These datasets have been made possible by significant public investment through the federal and state geological surveys and through research grants, backed by a publicly funded pool of high quality long-period and broadband instruments. Critical to the success of these datasets has been close cooperation between universities and the state and federal geological surveys. Private industry has also been involved in data collection, in supporting the push for national-scale datasets, and in co-funding some surveys. 

On this poster we present the current status of public MT data in Australia, showcasing the expansion of the AusLAMP array and highlighting some of the key inverse models that have been produced to date. The results from several dense, targeted surveys, including in the Cloncurry region in Queensland where 969 broadband MT stations were collected on a 2 km grid, are featured. In addition, we preview upcoming work, including WA MT which will extend the coverage of gridded lithospheric-scale MT into Western Australia. We also provide information on developments in how to access the data as both time series and transfer functions, including integration of open-source geophysical software into national high-performance computing resources.

Unearthing Australia’s subsurface secrets - An integrated FAIR modelling approach

Output Type: Exploring for the Future Extended Abstract

Short Abstract: To enable a sustainable and responsible use of the Earth's subsurface environment and accelerate Australia’s energy transition to net zero, industry and government rely on a quantified knowledge of Australia’s geology and structure to inform their decision-making. Despite the wealth of subsurface data available across the continent, including stratigraphic boreholes, geological and geophysical data, their uneven distribution, variable quality and diverse data formats prevent the development of consistent national subsurface models of Australia’s geology. A national coordination of data compilation with common standards, along with development of open-source modelling tools in line with the Findable, Accessible, Interoperable and Reusable (FAIR) principles are required to address this challenge. Here we present an open-source modelling methodology which provides a national seamless chronostratigraphic framework to assess the depth and spatial extent of geological and geophysical horizons to inform decisions on resource exploration and development. Using this approach, regional subsurface models across ~26% of Australia were generated, characterising depth and thickness of key stratigraphic sequences, i.e. Cenozoic, Mesozoic, Paleozoic and Neoproterozoic. Combined with the layered geology map of Australia, this work supports the basis for an integrated geological framework that facilitates data-driven decision making for decarbonation strategies, land-use management, exploration strategies and water management.&nbsp;

The occurrence of Lacazina and Biplanispira in the Mandated Territory of New Guinea; and, A Lower Miocene limestone from the Ok Ti River, Papua

A discovery of importance to the geology of the Mandated Territory of New Guinea, and especially as far as the Tertiary foraminifera-bearing rocks are concerned, was recently made by N. H. Fisher, Esq., M.Sc., Government Geologist of New Guinea. During a short stay at the Chimbu aerodrome, whilst the aeroplane was being unloaded, Mr. Fisher collected specimens of a limestone from a small creek near the aerodrome, which is in the Wahgi River area, New Guinea. In a communication to the writer, he stated that these limestones form steep escarpments along the Bismarck Range on the northern side of the Wahgi Valley. The elevation of the locality is 5,100 feet above sea level. When a microscopic study of thin sections of this limestone, which was sent to Canberra for examination, was carried out, it was found that the rock contained two foraminiferal genera that had not been previously recorded from the Mandated Territory. These genera were Lacazina and Biplanispira. Lacazina has been recorded by Dutch geologists from the Eocene of Dutch New Guinea but Biplanispira, as far as is known, has previously been determined only from the Eocene of Borneo.

MRTAS Norfolk Range totalcount 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 MRTAS Norfolk Range totalcount grid geodetic has a cell size of 0.00021 degrees (approximately 20m) and shows the terrestrial dose rate of the Arthur-Pieman Area, NW Tasmania, TAS, 1996. The data used to produce this grid was acquired in 1996 by the TAS Government, and consisted of 17093 line-kilometres of data at a line spacing between 100m and 200m, and 90m terrain clearance.
