Ural 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The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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.

Tropical Cyclone Risk Model

The Tropical Cyclone Risk Model (TCRM) is a stochastic modelling system intended for the evaluation of hazard and risk associated with tropical cyclones, specifically focused on wind hazard. It allows users to simulate a large (order thousands of years) catalogue of tropical cyclone events that are statistically similar to the historical tropical cyclone record (or other input tropical cyclone records). TCRM has been used to evaluate wind hazard at local and regional scales to inform risk assessments and multi-hazard mapping exercises. By using data extracted from global climate models, TCRM can also be used to evaluate future changes in TC hazard and risk. Users can also simulate single TC events to evaluate impacts in near-real time to inform emergency management and response activities. The TCRM code is written in Python, and can be executed on a range of computing architectures - massively parallel systems (e.g. NCI National Facility) to desktop computers - and operating systems (currently Windows and *NIX systems). By carefully designing and developing the software, we have accommodated a wide audience of potential users.

AUSGeoid98 v.1.0 data files:  (si49-02)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files.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.

Epoxy relief sediment-peel and latex-replication techniques used in the study of Spencer Gulf sediments

Some modifications to methods of relief peel preparation and latex replication have been made for use in the study of the evaporite and carbonate sediments and algal-mats of the peritidal regions of Spencer Gulf, South Australia. The use of hessian backing material enables araldite relief peels to be made of large faces of unconsolidated materials. A technique of cutting sediment cores to provide an undisturbed surface for preparing a peel has been developed to overcome problems of core disturbance or contamination caused by conventional methods of core sawing or core extrusion. Plaster-of-Paris moulds were taken of algal-mat surfaces, including some subject to daily tidal inundation, without extensively damaging the mats. Rubberlin latex casts of these moulds provide detailed replicas of the mat topography.

L212 Barkly 2D Seismic Survey

The Barkly 2D Seismic Survey was acquired during September to November 2019 and commenced near the town of Camooweal on the border of Queensland and Northern Territory. This project is a collaboration between Geoscience Australia (GA) and the Northern Territory Geological Survey (NTGS), and was funded by the Australian Government's Exploring for the Future program and the Northern Territory Geological Survey under Northern Resourcing the Territory initiative.
The Barkly seismic survey extends the 2017 South Nicholson seismic survey and links with the existing Beetaloo Sub-basin seismic data. The total length of acquisition was 812.6 km spread over five lines 19GA-B1 (434.6 km), 19GA-B2 (45.9 km), 19GA-B3 (66.9 km), 19GA-B4 (225.8 km) and 19GA-B5 (39.4 km). The Barkly seismic project provides better coverage and quality of fundamental geophysical data over the region from the southern McArthur Basin to northern Mt Isa western succession. The Barkly seismic data will assist in improving the understanding of basins and basement structures and also the energy, mineral and groundwater resource potential in Northern Australia. The new reflection seismic data and derivative information will reduce the risk for exploration companies in this underexplored area by providing information for industry to confidently invest in exploration activities.

Yilgarn Craton 1:1 million aeromagnetic interpretation dataset

This product covers interpretation of the full geophysical extent of the Yilgarn Craton, and also most of the Albany-Fraser province to the south-southeast. The interpretation covers the Meekatharra (SG50), Wiluna (SG51), Perth (SH50), Kalgoorlie (SH51), Albany (SHI50), and Esperance (SI51) 1:1M sheets. The data set predominantly addresses the Archaean rocks of the Yilgarn Craton but includes interpretation of the adjacent, abutting or onlapping Proterozoic rocks such as the Northampton Block, Yerida, Bryah, Padbury and Earaheedy groups, Albany-Fraser Province, Stirling and Mt Barren Beds, and Phanerozoic Perth and Officer Basins. The aeromagnetic interpretation provides most information on the distribution of the Archaean rocks as these rocks are generally moderately to highly magnetised with reasonable variation of magnetisation. Adjacent Perth Basin sediments are poorly magnetised and spatially associated magnetic anomalies are attributed to underlying Proterozoic rocks. The Archaean rocks are subdivided into undivided gneiss-migmatite-granite (Agmg), banded gneiss (Agn), sinuous gneiss (Anu), greenstone (Aa), and granite plutons (Ag). Where important relative differences in magnetisation are mapped, the geophysical map units include the suffixes _h (high), _m (medium), _l (low) and _r (remanent) for the level of magnetisation. Dykes, faults, and unassigned small intrusives are also mapped. Large Archaean domains equivalent to geologically defined Provinces are also defined including Narryer, Murchison, Toodyay- Lake Grace, Southwest, Southern Cross, Yeelirrie, Lake Johnston and Eastern Goldfields domains.

NDI Carrara 1 — A deep stratigraphic drillhole in the Carrara Sub-basin

In 2017, under the Federal Governments’ Exploring for the Future program, in collaboration with the NTGS under their ‘Resourcing the Territory’ initiative, Geoscience Australia acquired the South Nicholson Deep Crustal Seismic Reflection Survey in north-eastern Northern Territory.
 One of the key discoveries of this survey was the identification of a large sedimentary depocentre, concealed beneath the sedimentary rocks of the Cambrian Georgina Basin. This depocentre, up to 7 km deep, termed the ‘Carrara Sub-basin’ by Geoscience Australia (e.g. Carr et al., 2020), is interpreted to contain thick sequences of resource-rich Proterozoic rocks, broadly equivalent to rocks of the greater McArthur Basin (Northern Territory) and northern Lawn Hill Platform and Mount Isa Province of northwest Queensland, rocks that are highly prospective for sediment-hosted base metals and unconventional hydrocarbons.
The Carrara-1 stratigraphic drillhole was completed in late 2020, as a collaboration between Geoscience Australia, the Northern Territory Geological Survey and the MinEx CRC. Carrara-1 is the first drillhole to intersect the undifferentiated Proterozoic rocks of the Carrara Sub-Basin. 
Carrara-1 is located on the western flanks of the Carrara Sub-basin on the South Nicholson Seismic line (17GA-SN1), reaching a total depth of 1751 m, intersecting ca. 630 m of Cambrian Georgina Basin overlying ca. 1100 m of Proterozoic carbonates, black shales and minor siliciclastics. These rocks preserve evidence of both oil and gas and visible disseminated sulphide mineralisation. Carrara-1 affords us a privileged glimpse into this highly prospective and exciting frontier Proterozoic basin.
