Darwin Harbour Habitat Mapping Program: Predicted surface of Factor 1 from Principle Components Analysis on Elements dataset

This resource contains a PCA1 grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The PCA1 grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.

Hamersley Iron Detailed Data (P199964), 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 Hamersley Iron Detailed Data (P199964) contains a total of 77202 point data values acquired at a spacing between 100 and 2500 metres. The data is located in WA and were acquired in 1973, under project No. 199964 for Hamersley Iron Pty Ltd.

The 2003-04 Curnamona province seismic survey: Workshop notes

For over a decade Geoscience Australia has adopted a practice of releasing the processed seismic reflection data, together with an initial interpretation, as soon as possible after the completion of data acquisition. This policy reflects recognition that new data and ideas are a valuable resource for both researchers and the exploration industry, and that seismic data often provides new and quantitative insights into the structure of the crust at depth. This data and interpretation release is normally done in a workshop that is open to all comers, and with an understanding that not all ideas are fully developed.
The Curnamona Project is a collaborative project between PIRSA Minerals and Energy Resources, Geoscience Australia and the predictive mineral discovery Cooperative Research Centre (pmd*CRC) using the seismic acquisition facilities of the Australian National Seismic Imaging Resource (ANSIR). The aim of the Curnamona survey was to provide information on the crustal architecture of the southern Curnamona Province in both the highly prospective Palaeo- and Mesoproterozoic rocks and the overlying Neoproterozoic and Cambrian sequences. A particular objective was the imaging of the deeper crust and major structural features that may have influenced hydrothermal fluid flow and hence mineralisation.
The Curnamona seismic workshop is the first public display and discussion of data and results of the Curnamona seismic survey commenced in 2003 and completed in 2004 after being washed out by floods. Feedback on the seismic results back to GA and PIRSA project staff at this workshop is as valuable as the information flow to the workshop attendees, because it helps flesh out the geological understanding that is emerging from the seismic data.
Usually a quantity of seismic data, such as presented at this workshop, takes time to analyse and develop ideas as well as test hypotheses. At a detailed level, we have to continue to examine what the seismic data tells us about the minerals systems that operated within the Curnamona Province and how this knowledge may be used in minerals exploration. The complexity of the work requires collaboration and does not just rely on the expertise of seismic interpreters. Data processing, sequence stratigraphy, structural geology, tectonics, minerals systems, geochronology, and local and regional geology must all be taken into account.
The seismic results show us a crustal architecture for the Curnamona Province of eastern South Australia that provides important information on basement architecture that will enhance investment and targeting strategies for mineral explorers in the province. One example is the observation that the Kalkaroo prospect appears to be related to second order faults associated with hanging wall anticlines above a major bounding east-dipping fault at depth, opens up the possibility for further mineral deposits associated with other hanging wall anticlines above east-dipping faults.

Cobar P5009 EXT 2 Potassium ground concentration grid

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 radiometric potassium grid has a cell size of 0.00039074 degrees (approximately 40m) and shows potassium element concentration of the Cobar Magnetic and Radiometric Survey, 2021 in units of percent (or %). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

NSW DMR, Discovery 2000, 1994-95, AREA C, Bourke (P733), 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 NSW DMR, Discovery 2000, 1994-95, AREA C, Bourke survey were acquired in 1995 by the NSW Government, and consisted of 93000 line-kilometres of data at 250m line spacing and 60m 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.

Basement structure and its influence on the pattern and geometry of continental rifting and breakup along Australia's southern rift margin

Palaeogeographic reconstructions of the Australian and Antarctic margins based on matching basement structures are commonly difficult to reconcile with those derived from ocean floor magnetic anomalies and plate vectors. Following identification of a previously unmapped crustal-scale structure in the southern part of the Delamerian Orogen (Coorong Shear Zone), a revised plate reconstruction for these margins is proposed. This reconstruction positions the Coorong Shear Zone opposite the Mertz Shear Zone and indicates that structural inheritance had a profound influence on the location and geometry of continental breakup, and ocean fracture development. Previously, the Mertz Shear Zone has been correlated with the Proterozoic Kalinjala Mylonite Zone in the Gawler craton but this means that Australia is positioned 300-400 km too far east relative to Antarctica prior to breakup. Differences in the orientation of late Jurassic-Cretaceous basin-bounding normal faults in the Bight and Otway basins further suggest that extensional strain during basin formation was partitioned across the Coorong Shear Zone following an earlier episode of strike-slip faulting on a northwest-striking continental transform fault (Trans-Antarctic Shear).
