Southern Thomson Gravity Traverses P201401 SCBA267GU

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. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Southern Thomson Gravity Traverses P201401 SCBA267GU is a complete Bouguer anomaly grid for the Southern Thomson Gravity Traverses (P201401) survey. This gravity survey was acquired under the project No. 201401 for the geological survey of NSW, QLD. The grid has a cell size of 0.00096 degrees (approximately 100m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 3659 gravity stations were acquired to produce this grid.

Solid Geology of the Tennant Creek – Mt Isa area

Solid geology of the Tennant Creek to Mount Isa (TISA) area comprises four layers, namely: Mesozoic, Paleozoic, Neoproterozoic and Pre-Neoproterozoic. This is the first staged release of Geoscience Australia's national time based solid geology mapping program commenced under the Federal Government’s Exploring for the Future program. This product will be updated as the solid geology program progresses.
The solid geology layers were produced by interpretation of magnetic and gravity datasets and reference to available solid and surface geology maps, particularly GA's 1:1 M scale surface geology of Australia (2012), published 1:250 k scale map sheets, and the Northern Territory Geological Survey's solid geology maps of the Pine Creek (2005) and Tennant regions (2004). Drill hole constraints have been utilised where possible. Interpretations were compiled at 1:250 k scale and the final product is best utilised at this scale. Notably this release reveals the concealed extent of the Cambrian basalts of the Kalkarindji Igneous Suite, which extend over a large part of the TISA area.

The relationship between the Kaindi metamorphics and Cretaceous rocks at Snake River, Territory of Papua and New Guinea

Cretaceous rocks at Snake River, New Guinea, were previously regarded as part of the Kaindi Metamorphics. However, discordance and difference in metamorphic grade between the Cretaceous rocks (here named the Snake River Greywacke), and the more complexly folded and more highly metamorphosed Kaindi Metamorphics suggest that the metamorphics are considerably older than Cretaceous, and are probably Palaeozoic.

The central and southeast offshore Otway Basin well folio (metadata statement and digital data package)

Geoscience Australia (GA) has produced a folio of 32 wells across the central and southeast regions. This folio covers the areas from Normanby 1 on the Normanby Terrace, through the Shipwreck Trough and Nelson Sub-basin, to Whelk 1 in the southeast. Composite logs for each well in the folio include wireline logs, petrophysical analysis, interpreted lithology, organic geochemical data, organic petrology data, and sequence stratigraphic markers. This folio also includes core-based depositional environment (DE) and gross depositional environment (GDE) interval interpretations which were used to constrain wireline interpretation of DE/GDE away from core control. The folio includes the digital data package used to construct each well composite. The new folio complements a recently published folio of northeast offshore Otway Basin wells, and both were designed as resource for exploration in the offshore Otway Basin.

Cape Leeuwin, WA, 2011 (P1244), 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 South West (Cape Leeuwin - Collie), WA, 2011 survey were acquired in 2011 by the WA Government, and consisted of 101882 line-kilometres of data at a line spacing between 200m and 200m, 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.

Application of AEM for cover thickness mapping in the southern Thomson Orogen

The southern Thomson Orogen is a poorly understood crustal element of northwestern New South Wales and Queensland. The Southern Thomson Project, a joint research project between Geoscience Australia, the Geological Survey of New South Wales and the Geological Survey of Queensland, is improving mineral systems understanding of this under-explored orogen to encourage mineral exploration investment. The Project includes new pre-competitive geological and geophysical data collection and interpretation to inform stratigraphic drilling of strategic crustal elements within the southern Thomson Orogen.
Two AEM surveys were flown in 2014 and 2016, respectively. Results from these were interpreted using available stratigraphic borehole data and surface geological mapping to produce a new cover thickness model of the area that is used to interpret target depths for the stratigraphic drilling, and to inform on the validity of other pre-drilling geophysical methods.
This presentation presents highlights of the AEM data and discusses its implications for mineral exploration as well as long-term landscape evolution, neotectonism within the Eromanga and Lake Eyre basins and hydrostratigraphic unit mapping within the region. Results of the modelling will demonstrate that large portions of covered ground are within reach of exploration drilling.

Wanna 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Hydrocarbon Generation and Expulsion from Early Cretaceous Source Rocks in the Browse Basin, North West Shelf, Australia: a Small Angle Neutron Scattering and Pyrolysis Study

Small Angle Neutron Scattering (SANS), Rock-Eval pyrolysis and total organic carbon (TOC) analyses were carried out on 165 organic-rich Upper Jurassic-Lower Cretaceous sedimentary rock samples from nine wells in the Browse Basin (Adele-1, Argus-1, Brecknock South-1, Brewster-1A, Carbine-1, Crux-1, Dinichthys-1, Gorgonichthys-1 and Titanichthys-1). Cutting samples and some sidewall cores have been used. Out of the total 165 samples, 47 samples (22 for Brewster-1A and 25 for Dinichthys-1) were also analysed using the Ultra-small Angle Neutron Scattering (USANS) technique. The focus of the study was to identify potential Lower Cretaceous source rocks and the depth at which the onset of hydrocarbon generation occurred in each well, and to determine the onset of hydrocarbon expulsion in the wells for which USANS data were available.

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.
