Airborne Laser Fluorosensor (Mk III) Survey Reprocessing and Interpretation Report: WA-260-P, Timor Sea, Australia

The WA-260-P airborne laser fluorosensor (ALF) survey was flown by World Geoscience in the Timor Sea in October 1997 for BHP Petroleum and joint venture partners using the ALF MkIII system. The survey was designed to detect natural oil seepage over the permit in an effort to refine the petroleum prospectivity assessment.
The survey covers a triangular area over the northern two thirds of the permit and extends about 60km north to south and nearly 50km east to west at its widest section in the south.
This report is a re-interpretation of the World Geoscience data by Signalworks Pty Ltd using the ALF Explorer software. A total of 285 fluorescence anomalies (fluors) were picked out of the 1,751,550 recorded spectra in the final interpretation. This is an average fluor density of 0.16 fluors per thousand spectra.
The fluor distribution across permit WA-260-P is relatively uniform, with no strong oil seepage patterns evident. A possible band of more intense fluors lies on an E-W trend to the south of the Buller-1 and Cleia-1 wells.
The scattered distribution of detected fluors may be an indication of a working petroleum system. The known accumulations covered by the survey do not directly correspond with distinct clustering of fluors.

Desmodont bivalves from the Permian of eastern Australia

Bivalves of the genera Megadesmus Sowerby, pyramus, Myonia, and Astartila Dana, Vacunella Waterhouse, and Pleurikodonta Runnegar are common in the Permian strata of eastern Australia and are useful for both local and regional correlation. Some of these genera occur in New Zealand, Western Australia, India, and South America, but are uncommon in the northern hemisphere and appear to have been more or less endemic to the Gondwana province. Because of their common morphological features they can be grouped into a single family - the family Pholadomyidae.

Dumbleyung/Nyabing (Semi Detailed), WA, 2004 (P1086), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation 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 Dumbleyung/Nyabing (Semi Detailed), WA, 2004 survey were acquired in 2004 by the WA Government, and consisted of 4513 line-kilometres of data at 400m line spacing and 50m terrain clearance.

Southern Yilgarn (Newdegate), WA, 2004 (P1067), 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.

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.

Geophysical work at Heard Island 1951/52: establishment of seismological and magnetic observatories and initial results

The establishment of seismological and magnetic observatories at Heard Island is described. Brief descriptions and photographs of the huts and instruments are given. Earthquake phases recorded between April 1951 and February 1952 are listed, as are absolute magnetic observations made between July 1951 and January 1952. Although Heard Island has two active volcanic craters, the region is not very active seismically. Only two near earthquakes were recorded, both probably 2Â°.9 distant along the Kerguelen ridge. The absolute magnetic observations showed that the high rate of secular change in declination and horizontal intensity is continuing.

Assessment of the hydrostratigraphy for groundwater samples in the Broken Hill region.

The Curnamona Province and overlying basins (herein referred to as the Broken Hill region) contain many discrete groundwater systems. These include sedimentary aquifers of the Lake Eyre Basin, Eromanga Basin, Darling Basin and Arrowie Basin, as well as fractured rock aquifers of the Adelaide Superbasin and Curnamona Province. However, there is little known about the hydrogeology or hydrogeochemistry of these aquifers in the Broken Hill region. Given the semi-arid climate in this region, understanding these groundwater systems can better support sustainable use of the groundwater for agriculture, mining and potable water supplies.
&nbsp;
Aquifer attribution provides a fundamental starting point for any hydrogeological study. We will present recently released hydrogeochemical data for the Broken Hill region, and our subsequent process for assessing and attributing hydrostratigraphy to the samples. 
The Broken Hill Groundwater Geochemistry dataset (BHGG) was recently released in its entirety (Caritat et al. 2022 http://dx.doi.org/10.11636/Record.2022.020). It contains a compilation of archival CRC LEME hydrochemistry data that was collected as part of several projects from 1999 to 2005. This high-quality dataset contains 275 groundwater samples and includes a comprehensive suite of majors, minors, trace elements and stable isotopes (δ34S, δ18O, δ2H, δ13C, 87Sr/86Sr, 208/207/206Pb/204Pb). 

At the time of collection, some key bore metadata (e.g. bore depths, screen and aquifer information) were missing from the original data compilations and these metadata are crucial for any hydrogeological analysis and interpretation. Therefore, as part of the new BHGG data release we have developed a robust and consistent approach to add bore information and aquifer attribution, value-adding to the original BHGG chemical and isotopic data. This workflow utilises a combination of State databases, reports, field notes, drillhole compilations and geological maps, but still relied on local hydrological expertise to make decisions when encountering incomplete or conflicting information (which is reflected by a confidence rating on the attribution). 

The resulting BHGG product has supported re-assessment of the key hydrogeological and geochemical knowledge gaps in each groundwater system. An overview of knowledge gaps and the new sampling program being undertaken will be included in the presentation. &nbsp;

Explanatory notes of the 1:2 500 000 mineral deposits map of Papua New Guinea

The Mineral Deposits Map of Papua New Guinea has been compiled jointly by the Bureau of Mineral Resources (BMR) and the Geological Survey of Papua New Guinea. Open-file data have been used in the compilation of the map, which is envisaged as an aid to exploration and for official purposes; it is not intended to be a metallogenic map. Metals, mineral fuels, and industrial minerals are plotted but construction and fluxing materials and groundwater are excluded. The commodities in the map and tables are present in, or have been extracted from, each deposit as shown, and the importance of the deposit has been assessed on available information. The notes supplement the map by providing detailed information on each commodity. They are organized into sections which correspond to the commodity groups discussed below, and within each section the data on individual commodities are present in tabular form. Appendix II lists the commodities occurring in each Papua New Guinea 1:250 000 Sheet area. Figure 1 is a reference map of the Sheet areas.
