XRD Report - Mineralogy of NDI Carrara 1 Samples

The South Nicholson National Drilling Initiative (NDI) Carrara 1 stratigraphic drill hole was completed in late 2020, as a collaboration between Geoscience Australia, the Northern Territory Geological Survey (NTGS), and the MinEx CRC. The drilling aimed to gather new subsurface data on the potential mineral and energy resources in the newly identified Carrara Sub-basin. NDI Carrara 1 is located in the eastern Northern Territory, on the western flanks of the Carrara Sub-basin on the South Nicholson Seismic line, 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 (https://portal.ga.gov.au/bhcr/minerals/648482).
&nbsp;
Following a public data release of the borehole completion report, CSIRO was contracted by Geoscience Australia (GA) under the Exploring for the Future program to analyse samples from NDI Carrara 1 for quantitative bulk and clay fraction analysis. This report presents results for quantitative bulk and clay (<2 µm) fraction analysis by X-ray powder diffraction (XRD) on 32 bulk core samples from the NDI Carrara 1. Samples were prepared and analysed at the CSIRO’s Waite Laboratories in South Australia.

NSW DMR, Discovery 2000 Area N, Menindee, NSW, 1999 (P744), radiometric line data, AWAGS levelled

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.
 This NSW DMR, Discovery 2000 Area N, Menindee, NSW, 1999 (P744), radiometric line data, AWAGS levelled were acquired in 1999 by the NSW Government, and consisted of 41736 line-kilometres of data at 150m line spacing and 40m 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.

Evaluation of the NSHA23 Magnitude Conversion Equations Using a New Moment Magnitude Catalogue

An earthquake catalogue based on the moment magnitude scale (MW) is a prerequisite for global best practice seismic hazard analyses. The 2018 National Seismic Hazard Assessment (NSHA18) was the first national-scale seismic hazard assessment for Australia to apply magnitude conversions to express earthquake magnitudes uniformly in terms of MW. This approach led to the single-biggest change in seismic hazard estimates between Geoscience Australia-led national seismic-hazard models. Between the 2012 and 2018 assessments, the hazard reduced because of: 1) the general reduction in the number of earthquakes of magnitude 4.0 and larger due to the correction of local magnitudes (ML) and subsequent conversion to MW, and; 2) the increase in the Gutenberg-Richter b-value due to the non-linear conversion of local magnitudes ML to MW.
Using a new continental-scale attenuation model, independent assessment of MW has been performed for over 300 earthquakes recorded between 1990 and September 2024. After recalculating ML for the same earthquakes using improved filtering and time-domain windowing criteria, the MW catalogue is used to test and validate the ML to MW conversion equations used in the 2023 National Seismic Hazard Assessment (NSHA23). The earthquakes are partitioned into their regional magnitude polygons as applied by Geoscience Australia in its real-time operations; notionally central and western Australia, South Australia (Mt Lofty and Flinders Ranges) and eastern Australia. The performance NSHA23 ML to MW conversion equation is then assessed for each of these magnitude regions. Overall, the NSHA23 ML to MW conversion performs very well relative to continental-scale earthquake dataset. The sensitivity of this conversion to an earthquake’s static stress drop is also assessed. There is evidence that minor adjustments could be applied to the NSHA23 ML–MW conversion equation for larger-magnitude events with high stress drops.

AUSGeoid98 v.1.0 data files:  (sj52-13)

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.

Federal Electoral Divisions (March 2025)

The Parliament consists of the King (represented by the Governor-General) and two Houses (the Senate and the House of Representatives).
The House of Representatives reviews, debates and votes on proposed laws.
Each member elected to the House of Representatives represents a single electoral division, also known as an electorate, which does not cross state or territory borders.
Each of the six states, the Australian Capital Territory and Northern Territory gains representation in the House of Representatives in proportion to their population, and there are a similar number of electors in each electoral division within a given state or territory.
The names and boundaries of electoral divisions within a state or territory are reviewed periodically and may be adjusted.
This process is known as a redistribution of federal electoral divisions.
The Federal Electoral Divisions dataset contains the names and geographic boundaries of the federal electoral divisions in Australia.
The Senate is also often referred to as the ‘state’s house’ or the ‘house of review’.
The Senate's law-making powers are equal to those of the House of Representatives except that it cannot introduce or amend proposed laws that authorise expenditure for the ordinary annual services of the government or that impose taxation.
Those elected to the Senate are called ‘Senator’.
Senators represent all of one of the six states, the Australian Capital Territory or the Northern Territory.
There are 12 senators for each of the six states and there are two senators each for the Australian Capital Territory and the Northern Territory.
These boundaries are provided in vector format with Electoral Divisions represented by polygons.

Redistributions of federal electoral divisions are conducted of individual states or territories.&nbsp;The electoral divisions in this data have been used at general elections conducted since the date on which the redistribution was determined:
NSW - electoral divisions reflect changes made as a result of the redistribution of New South Wales determined on 10 October 2024.
VIC - electoral divisions reflect changes made as a result of the redistribution of Victoria determined on 17 October 2024.
QLD - electoral divisions reflect changes made as a result of the redistribution of Queensland determined on 27 March 2018.
WA - electoral divisions reflect changes made as a result of the redistribution of Western Australia determined on 24 September 2024.
SA - electoral divisions reflect changes made as a result of the redistribution of South Australia determined on 20 July 2018.
TAS - electoral divisions reflect changes made as a result of the redistribution of Tasmania determined on 14 November 2017.
ACT - electoral divisions reflect changes made as a result of the redistribution of the Australian Capital Territory determined on 13 July 2018.
NT - electoral divisions reflect changes made as a result of the redistribution of the Northern Territory determined on 4 March 2025.
