SHRIMPing beneath the Eromanga Basin: new insights into the evolution of the Thomson Orogen from SHRIMP U–Pb geochronology of basement drill cores

The Thomson Orogen of eastern Australia is a major component of the Tasmanides and has historically been poorly understood and overlooked for exploration due to extensive sedimentary cover including the Eromanga Basin. To further understanding and encourage exploration of this area, Geoscience Australia, the Geological Survey of Queensland and the Geological Survey of New South Wales (NSW) have undertaken a major multidisciplinary geoscientific programme in the southern Thomson Orogen (STO) as a part of the UNCOVER initiative. A major outcome of this project has been the completion of twelve stratigraphic diamond drill holes between 2016 and 2017. SHRIMP U–Pb zircon dating of magmatic and metasedimentary rocks intersected by the boreholes provide new insights into the geological evolution and mineral prospectivity of this region. Geochronology of three intrusive rocks intersected by new boreholes in the NSW part of STO have late Silurian ages of ~425 Ma (Tongo 1), ~421 Ma (Janina 1) and ~421 Ma (Congararra 1). The age of the granodiorite intersected by Tongo 1 is within uncertainty of the intrusion-related Mo-W and later Au-base metal mineralisation at the Cuttaburra and F1 prospects located ~20 km southeast of the Tongo 1 borehole. Additionally, previously unknown volcanic events have been revealed by a dacitic ignimbrite (~387 Ma) in borehole GSQ Eulo 2 (Queensland) and a rhyolite (~395 Ma) in borehole, Milcarpa 1 (NSW). Detrital zircon geochronology has also played an important role in characterising undercover units such as the Werewilka Formation and Nebine Metamorphics, interpreted from geophysical data sets.

St Arnaud/Bendigo West, (Kerang) Vic, 1980 (GSV0192) (P602), 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 St Arnaud/Bendigo West, (Kerang) Vic, 1980 (GSV0192) survey were acquired in 1980 by the VIC Government, and consisted of 55000 line-kilometres of data at 250m line spacing and 80m 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.

Correlation chart for the Permian system of Australia

The chart and accompanying notes and bibliography were prepared for publication in March 1971. Publication, however, was not undertaken at the time as the planned charts on the Carboniferous, Triassic, and Jurassic Systems were not ready (the Carboniferous chart has now been published: Bur. Miner. Resour. A us!. Bull. 156A, 1973). The chart has now been brought up to date and the most important subsequent papers have been included in the bibliography. The bibliography should, however, only be regarded as complete up to March 1971.

Problem constituents in Australian groundwater drinking-water supplies

Groundwater is a common source of drinking supply in Australias arid zone. The constituents in groundwater can limit its use either for drinking or for other domestic purposes. This paper discusses those constituents.  It also highlights popular misconceptions about water-quality problems associated with groundwater, and encourages radical rethinking to ensure that people in the arid zone can use available water supplies appropriately to maintain a healthy lifestyle.

AusArray: uncovering major crustal features using passive seismic data

It is generally accepted that improvements in mineral exploration are required to meet the rising demand for minerals associated with a transition to lower carbon energy sources. There is growing consensus in mineral exploration that the distribution of fertile mineral camps is controlled by major lithospheric structures yet there is a paucity of case studies with adequately distributed datasets to test this view. Here, we test the relationships between variations in the Mohorovičić discontinuity (Moho) and iron oxide-copper-gold and sediment-hosted mineral deposits in the regions between the Arunta and Mount Isa Provinces. We primarily utilise datasets from the Australian passive seismic array (AusArray) and pre-existing academic seismometer deployments supplemented by deep reflection seismic profiles. The 55–70 km seismometer interstation distance provides almost continuous imaging of the Moho interface using back-projected receiver functions. We observe the Moho surface undulates at depths of ~35 to ~50 km, reflecting the complex regional tectonic framework of the area. Sharp steps are observed associated with major crustal boundaries such as the Willowra Suture and the Cork Fault, while other changes are more gradual but on the first order correspond to lithospheric thickness variations. Inspection of the Moho surface and the spatial distribution of base metal deposits suggests that significant deposits (&gt;2 Mt) are distributed along the edges of second-order north–south to northeast–southwest-trending thicker crustal blocks. Our results indicate that passive seismic methods are a powerful tool to generate continues datasets across large regions from which important architectural features can be identified to support exploration under cover in frontier regions. Higher-resolution seismic surveys would be useful to link these structures with mineral camps in the near 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 Tanami NS 5S - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the NTGS Tanami NS 5S Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey.
This grid has a cell size of 0.00018 degrees (approximately 20m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2018 by the NT Government, and consisted of 15632 line-kilometres of data at 100m line spacing and 60m 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. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the NTGS Tanami NS 5S Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Water Properties of Ashmore Reef, North-west Shelf, Australia

Ashmore Reef is a tropical marine reserve positioned at the confluence of Indian Ocean waters and the Indonesian Through Flow, has three vegetated cays all with fresh water lenses and two lagoons, separated by a calcareous algal rise.  Both lagoons have two entrances on the northern side of the reef.  The reef is subject to a 4.75 m semi-diurnal tide and on a spring tide ~7.5 km3 of water washes over the reef.  The regional, lagoonal and well water qualities in and around Ashmore Reef have been observed from 1991 with a more intensive program since 1999 to ascertain it's chemistry and possible relationships with biodiversity.   Sea surface temperatures of the surrounding oceanic water seasonally range from 25.48Â°C to 30.2Â°C and salinity from 34.51 to 34.75.  Satellite derived lagoonal temperatures range from 25.4Â°C - 34.5 Â°C with an average of 29.4 Â°C, salinity ranges from 39.6 to 31.2.  
The fresh water lens on West Island has up to 150 000 ltr/yr pumped from the well. Well water temperature varies between 28Â°C and 29Â°C, and salinity has ranged from  0.03  to 3.94 with a pH of 7.64 dissolved oxygen percentage ranged from 27% to 51 %. 
This reef is within the tropical monsoonal belt, with thunderstorms occurring on ~85 days/yr and where evaporation potential is ~1820 mm, almost twice that of annual rainfall of ~950 mm.
