Kulgera (Victory Downs Station) Detailed Gravity Survey, NT, 2008 CR20090203 (P200883), gravity point data

Gravity data measures 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 Kulgera (Victory Downs Station) Detailed Gravity Survey, NT, 2008 CR20090203 (P200883) contains a total of 2632 point data values acquired at a spacing of 1000 metres. The data is located in NT and were acquired in 2008, under project No. 200883 for Quasar Resources Pty Ltd.

Shale Gas Prospectivity of the Lawn Hill Platform, Isa Superbasin

The Isa Superbasin is a Paleoproterozoic to Mesoproterozoic succession (approximately 1670-1575 Ma), primarily described in north-west Queensland. Despite the basin’s frontier status, recent exploration in the northern Lawn Hill Platform has demonstrated shale gas potential in the Lawn and River supersequences. Here, we characterise the unconventional reservoir properties of these supersequences, providing new insights into regional shale gas prospectivity.
The depths, thicknesses and mappable extents of the Lawn and River supersequences are based on the 3D geological model of Bradshaw et al. (2018). Source rock net thickness, total organic carbon (TOC), kerogen type and maturity are characterised based on new and existing Rock-Eval and organic petrology data, integrated with petroleum systems modelling. Petrophysical properties, including porosity, permeability and gas saturation, are evaluated based on well logs. Mineralogy is used to calculate brittleness (see also Jarrett et al., 2019, this volume). Regional stress and pressure regimes are also reviewed.
Abundant source rocks are present in the Isa Superbasin succession. Overall, shale rock characteristics were found to be favourable for both sequences assessed; both the Lawn and River supersequences host thick, extensive, and organically rich source rocks with up to 7.1 wt% total organic carbon (TOC) in the Lawn Supersequence and up to 11.3 wt% TOC in the River Supersequence. Net shale thicknesses demonstrate an abundance of potential shale gas reservoir units across the Lawn Hill Platform. 
With average brittleness indices of greater than 0.5, both the Lawn and River supersequences are interpreted as likely to be favourable for fracture stimulation. As-received total gas content from air-dried samples is favourable, with average values of 0.909 scc/g for the Lawn Supersequence and 1.143 scc/g for the River Supersequence
The stress regime in the Isa Superbasin and the surrounding region is poorly defined; however, it is likely dominated by strike-slip faulting. Modelling demonstrates limited stress variations based on both lithology and the thickness of the overlying Phanerozoic basins, resulting in likely inter- and intra-formational controls over fracture propagation. No evidence of overpressure has been observed to date, however, it is possible that overpressures may exist deeper in the basin where less permeable sediments exist.
This review of the shale reservoir properties of the Lawn and River supersequences of the Isa Superbasin significantly improves our understanding of the distribution of potentially prospective shale gas plays across the Lawn Hill Platform and more broadly across this region of northern Australia.

Widgiemooltha North, WA, 2013 (P1259), 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 Widgiemooltha North, WA, 2013 survey were acquired in 2013 by the WA Government, and consisted of 92768 line-kilometres of data at 100m 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.

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

The geology of the Georgetown-Clarke River area, Queensland

This Bulletin presents the results of a 4-year regional geological mapping programme, covering about 30,000 square miles in the Georgetown/Clarke River area of North Queensland,begun in 1956 and completed in 1959 by joint survey teams of the Bureau of Mineral Resources and the Geological Survey of Queensland. The area contains many goldfields, of which the Etheridge is the largest. Gold has been won here from about 1880 onwards, and other minerals were mined later. The area is covered by the Georgetown, Einasleigh, Gilberton, and Clarke River 1:250,000 Geological Series maps and by parts of the Croydon, Normanton, and Red River maps. It contains the Etheridge, Oaks, Gilbert. Percyville, Woolgar, and Balcooma Goldfields, the southern parts of the Chillagoe and Herberton Gold and Mineral Fields, and the eastern part of the Croydon Goldfield (Fig. 1). The Halls Reward copper deposit, the Perry Creek wolfram deposit, and the Gray Creek chromite deposit are situated near the eastern edge of the Georgetown / Clarke River area, and near the western limit of the Kangaroo Hills Mineral Field. A regional geological survey of the Georgetow n/Clarke River area was begun in 1956 by a combined party from the Bureau of Mineral Resources, Geology and Geophysics, and the Geological Survey of Queensland. Initially the party examined the radioactive anomalies located in 1954 and 1955 by a Bureau of Mineral Resources aerial scintillograph survey of the Atherton, Georgetown, Einasleigh, Gilberton, and Clarke River 1:250,000 Sheet areas. No economic deposit or radioactive minerals was discovered. The party then began systematic geological mapping in the Georgetown, Einasleigh, Gilberton, and Clarke River 1:250,000 Sheet areas to assess their mineral potential. In 1957 and 1958 geochemical and geophysical surveys were combined with detailed geological mapping at Halls Reward Copper Mine and the Gray Creek chromite deposit. Geological mapping of the four 1:250,000 Sheets was completed in 1959. when Mesozoic and Cainozoic sediments were examined.
