Carnarvon Special 1:250 000 topographic map

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.

Adavale Basin: Carbon storage package

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Adavale Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Adavale Basin.
The geological storage assessment for the Adavale Basin encompasses 8 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from well completion reports and government data sources (e.g. Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal) to inform the 4 components required for a potential geological storage of CO2 system. Thirty-nine boreholes in the Adavale Basin were used to map out gross depositional environments and their geological properties relevant for geological storage of CO2. From these datasets, the following properties have been evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity.
The data are compiled at a point in time to inform decisions on resource development opportunities. The data guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a prospective geological storage of CO2 system are explained and mapped. These data were then merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin at both play and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity in the Gumbardo Play interval.

Nymagee Helicopter (P198231), 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 Nymagee Helicopter (P198231) contains a total of 467 point data values acquired at a spacing of 5000 metres. The data is located in NSW and were acquired in 1982, under project No. 198231 for New South Wales Department of Mineral Resources (NSWDMR).

Precise U–Pb baddeleyite dating of the Derim Derim Dolerite: evidence for episodic mafic magmatism in the greater McArthur Basin

The Mesoproterozoic Roper Group of the McArthur Basin has excellent petroleum potential, but its poorly constrained post-depositional history has hampered resource exploration and management. The Derim Derim Dolerite occupies an important position in the regional event chronology, having intruded the Roper Group prior to deformation associated with the ‘Post-Roper Inversion’ event. It was assigned a magmatic crystallisation age of 1324 ± 4 Ma (uncertainties are 95% confidence unless otherwise indicated) in 1997, based on unpublished Sensitive High Resolution Ion Micro Probe (SHRIMP) U-Pb analyses of dolerite-hosted baddeleyite from sample 97106010, collected from the Derim Derim Dolerite type locality in outcrop within the northwestern McArthur Basin. Herein, we refine these data via Isotope Dilution-Thermal Ionisation Mass Spectrometry (ID-TIMS) analysis of baddeleyites plucked from the SHRIMP grain-mounts, which yielded a precise mean 207Pb/206Pb date of 1327.5 ± 0.6 Ma. This date is significantly older than a baddeleyite U-Pb ID-TIMS date of 1313.8 ± 1.3 Ma recently obtained from dolerite ALT-05, sampled in Pacific Oil and Gas Ltd drillhole Altree 2, near the northern margin of the Beetaloo Sub-basin, and 200 km south of 97106010. This pair of results indicates that Derim Derim Dolerite magmatism spanned at least 10-15 Ma. Previously documented geochemical variation in Mesoproterozoic mafic rocks across the Northern Territory (such as the 1325 ± 36 Ma (2σ) Galiwinku Dolerite in the northern McArthur Basin, 1316 ± 40 Ma phonolites intruding the eastern Pine Creek Orogen, and 1295 ± 14 Ma gabbro in the Tomkinson Province) may reflect episodic pulses of magmatism hitherto obscured by the low precision of the available isotopic dates.

New SHRIMP U-Pb zircon ages from the Wau-Bulolo region, Papua New Guinea

This Record presents new zircon U Pb geochronological data obtained via Sensitive High Resolution Ion Micro Probe (SHRIMP) from rocks sampled within the Wau 1:100 000 map sheet area, which is located on the Papuan Peninsula in eastern Papua New Guinea. Exposure in the Wau Bulolo region comprises low-grade Mesozoic metasedimentary rocks of the Owen Stanley Metamorphics, which are intruded by the mid-Miocene Morobe Granodiorite batholith, and overlain by Pliocene sedimentary and volcanic rocks of the Wau Basin. The map sheet area contains the Morobe Goldfield (from which more than 3.2 Moz of alluvial gold has been mined) and the Hidden Valley epithermal Au-Ag deposit (which has a total gold resource in excess of 3 Moz), and lies about 70 km south-southeast of the giant mid-Miocene Wafi-Golpu porphyry Cu-Au deposit (&gt;26 Moz Au and 9 Mt Cu).
The geochronological data in this Record were generated as part of a collaborative project between Geoscience Australia (GA) and the Mineral Resources Authority (MRA) of Papua New Guinea in 2012. Four samples were analysed: two from the Pliocene Bulolo Volcanics and one from the Miocene Morobe Granodiorite to establish precise, accurate magmatic crystallisation ages, and one metasandstone from the Mesozoic Owen Stanley Metamorphics for detrital zircon provenance analysis. Sample locations, descriptions, and U Pb SHRIMP results are summarised in Table 1.1.

National EO Validation Campaigns – a proven capability to build on. The L8/L9 Underfly Example

The recent federal funding of the National Space Mission for Observation is in no small part a recognition of the capability of the Australian EO community and central to this is the ability to mount effective national-scale field validation programs.

After many delays, Landsat 9 was launched on the 27th September 2021. Before being handed to the USGS for operational use, NASA had oversight of configuring and testing the new platform and navigating it into its final operational orbit.&nbsp;For a brief few days and a handful of overpasses globally, Landsat 9 was scheduled to fly ‘under’ its predecessor Landsat 8. &nbsp;This provided the global EO community a ‘once in a mission lifetime’ opportunity to collect field validation data from both sensors.

At short notice the USGS were advised on the timing and location of these orbital overpasses. &nbsp;For Australia, this meant that between the 11th and 17th&nbsp;of November we would see a single overpass with 100% sensor overlap and three others that featured only 10% overlap. Geoscience Australia (who have a longstanding partnership with the USGS on satellite Earth observation) put out a call to the Australian EO community for collaborators.

Despite this compressed timeline, COVID travel restrictions and widespread La Niña induced rain and flooding, teams from CSIRO, Queensland DES, Environment NSW, University of WA, Frontier SI and GA were able to capture high value ground and water validation data in each of the overpasses.

Going forward, the Australian EO community need to maintain and build on these skills and capabilities such that the community can meet the future demands of not only our existing international EO collaborations but the imminent arrival of Australian orbiting EO sensors.

NW Tasmania, TAS, 1984 (P494), 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 NW Tasmania, TAS, 1984 survey were acquired in 1984 by the TAS Government, and consisted of 13430 line-kilometres of data at 500m line spacing and 150m 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.

An instrument for simultaneous measurement of Eh and pH in boreholes

An instrument is described that measures Eh and pH simultaneously in boreholes. The temperature of the borehole fluid and its self-potential with respect to an up-hole mud probe can also be measured. Operation should be possible in water depths to 100 m. By connecting the pH electrode system in a feedback circuit, electrometer amp lifier performance is obtained from a cheaper, lower quality amplifier.  Signal subtraction operations allow the same reference electrode to be used simultaneously for all measurements. Sources of error are reduced by careful guarding of the high-resistance input circuits and by using isolation amplifiers to prevent ground leakage currents. A number of future development possibilities are indicated.
