AFGN Absolute Riverina Gravity Survey (P201390), 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 AFGN Absolute Riverina Gravity Survey (P201390) contains a total of 6 point data values acquired at a spacing of 750 metres. The data is located in NSW, VIC and were acquired in 2013, under project No. 201390 for Geoscience Australia.

Structural and pressure-temperature evolution of host rocks of the Giles Complex, western Musgrave Block, central Australia: evidence for multiple high-pressure events

The history of Mid-Proterozoic metasedimentary gneisses, felsic and mafic orthogneisses of the Tomkinson Ranges, western Musgrave Block, involved multiple low- to high-P metamorphic events and polyphase deformation. Isoclinal, gently inclined to recumbent D1/2 folding accompanied the intrusion of pre-S1 mafic and felsic orthogneisses and post-S1 , pre-S2 felsic orthogneisses under peak conditions of P=5Â±1 kbar and T-750 Â°C at ~1200 Ma.  K-feldspar megacrystic granitoid stocks formed at ~1188 Ma.  Post-S2 mafic to ultramafic magmatism resulted in the large layered intrusions of the Giles Complex at ~1080 Ma, whilst the terrane was at conditions of P=6Â±1 kb. At ~1080-1060 Ma, microgranitoid dykes and veins intruded Giles Complex sills in the Tomkinson Ranges, while comagmatic volcanics of the Tollu Group unconformably overlie other parts of the Musgrave Block further west. Type A mafic dykes, which may represent feeder veins to the Tollu Group, intruded rocks of the Tomkinson Ranges before a third deformation event, D3, resulted in a system of steep, southeast-trending mylonites with a granulite facies S3 foliation and a well-developed down-dip L3 stretching lineation.  Type A mafic dykes and their host felsic granite gneiss show marginal to complete recrystallisation to granulite facies mylonitic S3 assemblages at conditions of P-11 kb and T-700Â°C. Near-isothermal decompression returned such parts of the Musgrave Block to conditions of P-4-5 kb late in D3. Parts of the Musgrave Block that are unconformably overlain by the Tollu Group probably remained closer to the earths surface during D3. Coarse-grained, ~800 Ma Type B mafic dykes and aphanitic, ~1000 Ma Type C mafic dykes cut S3, and are cut by a system of mylonite and retrograde shear zones, D4-7.  East-trending ~550 Ma D6 ultramylonite pseudotachylite zones represent the effects of the Late Proterozoic to Cambrian Petermann Orogeny, which resulted in significant dislocation of parts of the Musgrave Block and the partial to complete recrystallisation of post-S3 dykes near the Woodroffe thrust zone at sub-eclogite facies conditions of P=14Â±1 kb and T=700-750Â°C.  These late high-pressure assemblages suggest that the structural grain in rocks of south-central Australia resulted, to a major extent, from Late Proterozoic to Cambrian compression.

Summary Of Data And Results Perth Basin, Western Australia Jurien No. 1 Abbarwardoo No. 1 Eganu  No. 1 Of West Australian Petroleum Pty Limited

Jurien No. 1 Well was located on the western margin of the Perth Basin,  Western Australia, approximately 76 miles south-south-east of Geraldton. The well was drilled by Oil Drilling and Exploration (W.A.) Fty Limited for West Australian Petroleum Fty Limited, to a total depth of 3366 feet. Drilling commenced on 9th July, 1962, and was completed on 21st August, 1962. A full programme of logging, testing, and coring was undertaken.
The well was spudded in the Coastal Limestone of Pleistocene age, and penetrated 811 feet of Lower Triassic Kockatea Shale; 2274 feet of Permian (Artinskian) sediments; 35 feet of (1) Permian sandstone, and entered Precambrian granitic gneiss at 3208 feet.
The well was drilled to investigate the stratigraphy and petroleum potential of the Permian sediments in the Jurien Anticline. At least 200 feet of structural closure over eight square miles were proved for that area on the basement refractor. The main objectives were the sandstones in the Irwin River Coal Measures and High Cliff Sandstone. No potential reservoir beds were observed and only the Lower Triassic Kockatea Shale appeared to be a good source rock for hydrocarbons although minor oil traces were observed in some of the Permian section.
Three drillstem tests were carried out over the intervals 552 to 595 feet, 1940 to 2020 feet, and 2196 to 2356 feet. No water, oil, or gas was recovered in any of the tests. 
The stratigraIilic drilling operation at Jurien No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.

Don King Notebook 1 : Don's Diary

Three geologists left Australia in 1951 to conduct geological surveys in Pakistan, under the auspices of the Colombo Plan which provides technical assistance for member countries in South and South East Asia. The main objects were to conduct an economic and general geological survey of a selected part of the Gilgit Agency, to examine the alluvial-gold prospects of the Chitral River, and, if time permitted, to discuss the Sind and East Bengal lignites with the Director of the Pakistan Geological Survey.
The field notebooks contain the geological observations recorded by the geologists during their trip. Files include a scanned copy of the original handwritten field notebook, transcription of the notebook’s contents, and a csv file of the transcription with Text Encoding Initiative (TEI) tags. The original field notebooks are held at the N.H. (Doc) Fisher Geoscience Library at Geoscience Australia, Canberra.

Integrated satellite clock and code phase bias combination in the third IGS reprocessing campaign

In the third reprocessing campaign (repro3) initiated by the International GNSS Service (IGS), 11 analysis centers (ACs) reanalyzed GPS/GLONASS/Galileo observations spanning 1994–2020 for station coordinates, satellite orbits, clocks, biases and attitudes. To improve the robustness of satellite products, the IGS AC Coordinator (ACC) carried out the satellite orbit combination, and the reference satellite attitudes were computed by the Technical University of Graz (TUG). The clock/bias combination was performed by Wuhan University via the IGS “Precise Point Positioning with Ambiguity Resolution” (PPP-AR) Pilot Project using the PRIDE ckcom software. 

This article aims at reporting the clock/bias combination results in the repro3. In particular, the consistencies for the combined GPS P1–P2/Galileo C1–C5 differential code biases (DCBs) and the GPS/Galileo uncalibrated phase delays (UPDs) among contributing ACs are all better than 0.1&nbsp;ns and 0.05 cycles, respectively. As a result, the consistencies for the combined GPS/Galileo satellite clocks/biases are better than 10&nbsp;ps, equating about 3&nbsp;mm which is very close to the nominal precision of carrier-phase. In general, the Hadamard deviation and PPP-AR results confirm the higher robustness of the combined satellite clock/bias products over their original AC-specific counterparts. This is because the combined satellite clock/bias products harvest the merits of AC-specific contributions by identifying and excluding outlier solutions from the combination process.

Rule-based semi-automated tools for mapping seabed morphology from bathymetry data

Seabed morphology maps and data are critical for knowledge-building and best practice management of marine environments. To facilitate objective and repeatable production of these maps, we have developed a number of semi-automated, rule-based GIS tools (Geoscience Australia’s Semi-automated Morphological Mapping Tools (GA-SaMMT)) to operationalise the mapping of a common set of bathymetric high and bathymetric low seabed Morphological Features. The tools have a graphical user interface and were developed using Python scripts under the widely-used proprietary ArcGIS Pro platform. The utility of these tools was tested across nine case study areas that represent a diverse range of complex bathymetric and physiographic settings. Overall, the mapping results are found to be more consistent than manual mapping and allow for capture of greater detail across a range of spatial scales. The mapping results demonstrate a number of advantages of GA-SaMMT, including: 1) requirement of only a bathymetry grid as sole data input; 2) flexibility to apply domain knowledge to user-defined tool parameters or to use default parameter settings; 3) repeatability and consistency in the mapping outputs when using a consistent set of tool parameters (user defined or default); 4) high-degree of objectivity; and 5) efficiency in mapping a large number (thousands) of seabed morphology features in a single dataset. In addition, GA-SaMMT generates 34 and 46 metrics to comprehensively quantify the characteristics of individual seabed bathymetric high and low features, respectively. Our results indicate that attribute metrics are invaluable in the interpretation and modelling of mapped Morphology Features and provide insights into their formative processes and habitat potential for marine communities.
