Architecture, evolution and fertility of the Delamerian Orogen: Insights from zircon

Magmatic arcs represent a critical source of modern civilisation’s mineral wealth, with their importance only enhanced by the ongoing global transition to a low-carbon society. The ~830-495 Ma Delamerian Orogen, formed at Australia’s eastern cratonic margin, represents rocks ascribed to rift/passive-margin, convergent margin arc, orogenic, and post-orogenic settings. However, poor exposure has limited exploration activity across much of the orogen, despite demonstrated potential for numerous mineral systems. To address this issue, an orogen-wide zircon Hf-O isotope and trace element survey was performed on 55 magmatic samples to constrain the crustal architecture, evolution, and fertility of the Delamerian Orogen, and in turn map parameters that can be used as a guide to mineral potential. These new data define two broad magmatic episodes at: (1) ~585-480 Ma, related to rift/passive margin, convergent arc, orogenic, and post-orogenic activity (Delamerian Cycle); and (2) magmatism associated with the ~490-320 Ma Lachlan Orogen, with peaks at ~420 Ma (onshore, Tabberabberan Cycle) and ~370 Ma (western Tasmania). Isotopic and geochemical mapping of these events show that the ~585-480 Ma Delamerian Cycle has significant orogen-wide variation in magmatic Hf-O isotopes and oxidation-state, suggesting a spatial variation in the occurrence and type of potential mineral systems. The ~420 Ma magmatic event involved predominantly mantle-like Hf-O and oxidised magmatism, whilst the ~370 Ma magmatism shows opposing features. In general, The potential to host Cu-Au porphyry and VMS mineralisation (e.g., Stavely, Koonenberry) is present, but restricted, whereas signatures favourable for Sn-W granite-hosted systems (e.g., Tasmania), are more common. These new data constrain time-space variations in magma composition that provide a valuable geological framework for mineral system fertility assessments across the Delamerian Orogen. Furthermore, these data and associated maps can used to assess time-space mineral potential and facilitate more effective exploration targeting in this covered region.

Meelera Rockhole B Gravity (P198184), 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 Meelera Rockhole B Gravity (P198184) contains a total of 170 point data values acquired at a spacing of 200 metres. The data is located in SA and were acquired in 1981, under project No. 198184 for Afmeco Pty Ltd.

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.

Geology and economic potential of the Palaeoproterozoic layered mafic-ultramafic intrusions in the East Kimberley, Western Australia

The Palaeoproterozoic layered mafic-ultramafic intrusions in the Halls Creek Orogen of the East Kimberley, Western Australia, represent one of the most extensively mineralised igneous associations of their type in Australia. They contain a range of magmatic and hydrothermal deposits of platinum-group elements, chromium, nickel, copper, cobalt, titanium, vanadium, iron, and gold.
Bulletin 246 presents the results of a collaborative AGSO/Geological Survey of Western Australia/Monash University/minerals industry study of the geology and mineral potential of these intrusions. It is an essential reference for those involved in the exploration of layered mafic-ultramafic intrusions, the geology of the Halls Creek Orogen and its environs, or the study of Precambrian orogenic terranes.

A recently discovered unconformity near the base of the Proterozoic Cloncurry Complex south of Mount Isa, northwestern Queensland

Recent mapping of Precambrian rocks in the southwestern part of the Mount Isa-Cloncurry region has revealed for the first time a major unconformity between the Kalkadoon Granite-Leichhardt Metamorphics basement complex and overlying regionally metamorphosed basic and acid volcanic units tentatively correlated with the Magna Lynn Metabasalt and Argylla Formation, respectively. These units flank the western margin of the basement complex, and are overlain, apparently conformably, by the Mount Guide Quartzite.

Source rocks and hydrocarbon potential of the Palaeozoic in the onshore Canning Basin, Western Australia

In the onshore Canning Basin potentially oil-bearing sediments are restricted to the Palaeozoic sequence. Analyses of organic content of the most promising source lithologies show that there is some source potential in the Ordovician of the Broome Arch and other areas, in the Devonian and Lower Carboniferous of the margins of the Fitzroy Graben and adjacent terraces, and in the Permian of the Fitzroy Graben. A review of the hydrocarbon potential of the basin suggests that there is some hope for future successful exploration, particularly in the unexplored southeast Fitzroy Graben. The data available from the scattered and often poorly sited exploration wells nevertheless indicate that because of unsuitable organic material, poor reservoir conditions, and unfavourable burial histories, the area may never become a major hydrocarbon producing province.

Tasmanian Tiers Airborne Magnetic, Radiometric and Digital Elevation Survey, TAS, 2021, (P5003), total magnetic intensity, reduced to pole grid

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.
This magnetic grid has a cell size of  degrees (approximately 40m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the TAS Government, and consisted of 32951 line-kilometres of data at 200m line spacing and 80m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.
