Whole-rock inorganic geochemistry of sedimentary rocks from northern Australia

The Exploring for the Future Program (EFTF) is a $100.5 million four year, federally funded initiative to better characterise the mineral, energy and groundwater potential of northern Australia.  As part of this initiative, this record presents new whole-rock geochemistry data from 967 samples of sedimentary rocks sampled from 26 wells in the South Nicholson region, including the Proterozoic South Nicholson Basin and Lawn Hill Platform, the Neoproterozoic to Devonian Georgina Basin and the Jurassic to Cretaceous Carpenteria Basin. This work complements other components of the EFTF program, including the South Nicholson Basin seismic survey, a comprehensive geochronology program and hydrocarbon prospectivity studies to better understand the geological evolution and basin architecture of the region, and facilitate identification of areas of unrecognised resource potential and prospectivity. 
The South Nicholson region, straddling north-eastern Northern Territory and north-western Queensland, arguably represents one of the least geologically understood regions of Proterozoic northern Australia. The South Nicholson region is situated between two highly prospective provinces, the greater McArthur Basin in the Northern Territory, the Lawn Hill Platform and the Mount Isa Province in Queensland, both with demonstrated hydrocarbon and base metal potential. These new geochemical data provide baseline understanding of regional resource prospectivity of sedimentary rocks in the South Nicholson region.
During 2017 and 2018, 967 drill core and cuttings were sampled from 26 legacy boreholes that intersected the South Nicholson region housed in Northern Territory Geological Survey’s core repository in Darwin, the Geological Survey of Queensland’s core repository in Brisbane and Geoscience Australia’s core repository in Canberra. 
This data release contains the results of elemental analyses on these samples, which include X-Ray Fluorescence (XRF), Loss-On-Ignition (LOI), Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) for all samples, in addition to ron titration (FeO) for selected samples. 
The data was generated in the Inorganic Geochemistry laboratory at Geoscience Australia between 2017 and 2019 as part of the EFTF program. All data was quality controlled based on Certified Reference Material standards (CRMs) and duplicate samples analysed with each batch of samples.

Report on the Analysis of the Asia Pacific Regional Geodetic Project (APRGP) GPS Campaign 2021

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). The WG continues to undertake an annual GPS campaign activity as some member countries are unable to participate in the Asia Pacific Reference Frame (APREF) project but have an ongoing requirement for geodetic positioning relative to a stable global/regional reference network. One of the roles of the WG is to create and maintain a densely realised and accurate geodetic framework, coordinate regional cooperation in geodesy amongst national agencies, and to build and improve the regional geodetic infrastructure. The APRGP is where UN-GGIM-AP member agencies contribute GPS data to the WG. GPS data from the APRGP are available for all participant member countries for local and global scientific research and local applications. The composite GPS data set is subsequently analysed by the WG to provide estimates of station coordinates in the International Terrestrial Reference Frame (ITRF). The results of the APRGP are also supplied by the WG to the official ITRF product centre to densify the ITRF in the Asia Pacific region. This document overviews the data analysis of APRGP GPS campaign undertaken in 2021.

Mount Bischoff mine ore reserves at November, 1944

A geological survey of the mount Bischoff Mine area was commenced in January, 1944, with the objects of delimiting the known ore shoots, determining the field relationships of those and so arriving at an understanding of ore occurrence which could be applied to the location of possible new shoots.  By April the open cut area had been surveyed accurately and in detail, a general geological reconnaissance made and detailed geological mapping carried out of half of the open cut and a considerable part of the area outside the open cut. This report comprises a discussion of existing and suspected ore reserves. The report includes an assay plan and a diagram of assay sections of the Greisen orebody.

Beach sands investigations: The "Trough" area, South Stradbroke Island

The "Trough" area extends parallel to and 200 to 300 feet west of the eastern beach from approximately 4800 feet north of the zero-line shown on the locality plan, to 6000 feet south of the zero line. A previous report (Record 1948/067) has given an estimate of the quantities of heavy mineral occurring from 2100 feet north to 1100 feet north. The following report deals with the remaining areas. The area was sampled during 8th and 9th September, 1948. Where the heavy minerals were at or close to the surface, samples were obtained from shovel holes. Where the mineral was at some depth below the surface, the samples were obtained from bores put down with a post-hole digger. Estimates of the quantities and grades of heavy mineral concentrates, the quantities of overburden, and the quantities of each of the heavy minerals are tabulated in this report. The data sets from which these estimates are derived are appended.

Radiometric investigations on the Sunnyside Goldfield

During May, 1950, a sample of granitic material was obtained from a dump on the Sunnyside goldfield, and showing a few flakes of a green mineral similar in appearance to torbernite, was forwarded to the Department of Mines, Melbourne, by a miner working on that field. The Mines department tested the mineral and proved that it was uranium-bearing, and submitted a sample to the Bureau to test for radioactivity. After confirmation of the presence of radioactivity in the sample by laboratory tests, a brief visit was paid to the field by a party from the Geophysical Section. One day was spent for conducting tests on the field. The opportunity was taken of visiting the Maude and Yellow Girl mine, and testing ores and concentrates for radioactivity.

Temporal and fine-scale variation in the biogeochemistry of Jervis Bay

The identification of suitable abiotic surrogates for biological diversity requires the collection of both physical and biological data. However, logistical constraints often preclude experimental designs that incorporate spatial and temporal replication. Given the quite limited resources normally available for surveys, the investigation of appropriate surrogates involves a trade-off between overall spatial coverage and replication. We have completed a survey in Jervis Bay in which environmental and infaunal data were collected contemporaneously in order to be combined with similar data from a previous winter survey (survey number GA309) to investigate variation across seasons. Because there will be a certain error in sampling at the exact location as the previous survey, the survey design also required that replicate samples be taken at a set number of stations in order to investigate fine-scale variability (at the scale of metres).
We used grabs to collect paired geochemical and biological samples from thirty-two stations in a defined grid near Darling Rd; at eight of these stations we deployed three pairs of grabs to investigate fine-scale variability. Due to good weather and extra ship time available, we also deployed a CTD to investigate vertical temperature and salinity profiles at each station in the Darling Rd grid, as well as at stations throughout the entire bay. Samples are expected to be processed and analysed by late 2009, but preliminary results indicate that most physical variables and infaunal assemblages varied between seasons. In addition, variation among infaunal assemblages seems greater among stations (hundreds of meters) than within replicates at stations (meters).

Compositional Kinetics for the Lower Cretaceous Eumeralla Formation, Otway Group, Otway Basin, Australia

Geoscience Australia currently uses two commercial petroleum system modelling software packages, PetroMod https://www.software.slb.com/products/petromod and Zetaware http://www.zetaware.com, to undertake burial and thermal history modelling on wells in Australian sedimentary basins. From the integration of geological (age-based sedimentary packages, uplift and erosional events), petrophysical (porosity, permeability, and thermal conductivity) and thermal (downhole temperature, heat flow, vitrinite reflectance, and Tmax) input data, to name the most significant, a best-fit model of the time-temperature history is generated. Since the transformation of sedimentary organic matter (kerogen) into petroleum (oil and gas) is a chemical reaction, it is governed by chemical kinetics i.e. time and temperature (in the geological setting, pressure is of secondary importance). Thus, the use of chemical kinetics associated with a formation-specific, immature potential source rock (where available) from the basin of interest is considered a better practical approach rather than relying on software kinetic defaults, which are generally based on the chemical kinetics determined experimentally on Northern Hemisphere organic matter types.
As part of the Offshore Energy Systems program hydrocarbons from the Lower Cretaceous Eumeralla Formation were selected where available from onshore wells; compositional kinetics (1-, 2-, 4- and 14-component (phase) kinetics) were undertaken by GeoS4, Germany. The phase kinetics approach is outlined in Appendix 1. This report provides the compositional kinetics for potential source rocks from the Lower Cretaceous Otway Group, Otway Basin, Australia. The kinetic data were used in the offshore petroleum system modelling reported in Schenk et al. (2021).

Notes on the occurrence of lateritic soil at Sogeri, Papua

As a results of representations made to the Bureau of Mineral Resources by the Australian Aluminium Production Commission during 1948 a brief examination was made in July, 1949, of the area known as Sogeri Plateau which is situated some 24 miles east-north-east of Port Moresby. The object of the inspection was to determine whether any bauxitic laterite was present on the plateau and if so to obtain samples for chemical determination of alumina soluble in caustic soda solution, that is, alumina extractable by the Bayer process. Three car traverses of the area were made - one along the Sogeri-Uberi road, one along the Sogeri-Subitana road and one along the Sogeri-Eilogo road. Two grab samples were collected and sent for analysis. The findings of the examination of the area and the results of the chemical analyses are described in this report.

Raw materials for the manufacture of cement in the Port Moresby area, Papua

In January 1949 a brief examination was made of the area bounded by the Port Moresby - Rouna Road, the Rigo Road and the coastline between Port Moresby and Bogora Inlet, with the object of determining whether supplies of water and raw materials for the manufacture of cement were available. Possible quarry sites were chosen and specimens of the likely raw clay materials, of the limestone at Boatless Inlet, of reef limestone and limestone from the Main Road (or "Nine Mile") Quarry collected. Fourteen of these specimens are being analysed for silica, alumina, lime, iron, magnesia, carbon dioxide and water and total alkalies. As the suitability of the various raw materials examined depends largely on their chemical composition, this report must be regarded as only a preliminary one until these results are received. In this report the availability of raw materials and the general geology of the area are discussed, and a description given of the deposits of raw materials examined in the course of the visit.

Australia's Energy Commodity Resources (AECR), 2023 Edition

Australia’s Energy Commodity Resources (AECR) provides estimates of Australia’s energy commodity reserves, resources, and production as at the end of 2021. The 2023 edition of AECR also includes previously unpublished energy commodity resource estimates data compiled by Geoscience Australia for the 2021 reporting period. The AECR energy commodity resource estimates are based primarily on published open file data and aggregated (de identified) confidential data. The assessment provides a baseline for the production and remaining recoverable resources of gas, oil, coal, uranium and thorium in Australia, and the global significance of our nation’s energy commodity resources.

Coal in the Northern Territory

In Australia, coal seams occur in stratified rocks of Permo-Carboniferous, Triassic, Jurassic and Tertiary systems. Black coal occurs in the rocks of the first three systems, and brown coal in the Tertiary. In the Northern Territory, Permo-Carboniferous, Jurassic and Tertiary rocks are present. Coal has been found in the Northern Territory, but none of the occurrences are of commercial importance. The occurrence of coal in the Port Keats - Cliff Head, North and East Coast, and Hale River districts is discussed in this report.

Occurrence and distribution of oil in the glauconitic sandstone at and around the Lakes Entrance shaft; with a discussion of factors affecting probable oil recovery

Recently, it was desired for engineering and other purposes to test the micaceous marls and the glauconitic sandstone below the bottom of the shaft. It was decided to put down a diamond drill hole and to use the cores for necessary testing. This report deals mainly with the examination of the cores of glauconitic sandstone obtained from the drill hole. An attempt has been made to correlate much of the available data on the Lakes Entrance field which has a bearing on the Lakes Entrance oil project, and to provide a summary of the occurrence and distribution of oil in the glauconitic sandstone. Finally the report includes a critical examination of the factors influencing the recovery of oil from the glauconitic sandstone by horizontal oil wells, and an estimate of the percentage of oil which might be recoverable from a given area at Lakes Entrance.

Gravity survey: Walloway Artesian Basin, South Australia

The Walloway Artesian Basin is approximately 160 miles north of Adelaide and is traversed by the main road from Adelaide to Maree via Orroroo and Hawker. The town of Orroroo lies on its western margin in the south-western corner of the Hundred of Walloway and the village of Johnburgh is situated in its northern part. The geophysical survey was carried out at the request of the Director of Mines for South Australia to assist his Department in the selection of sites for boring for artesian water and to delineate more precisely the limitations of the basin with regard to artesian flows. The gravity method was used as this method has proved successful elsewhere in determining the dimensions and form of sedimentary basins. This report gives an account of the survey and its results.

Geological report on the Chilcot copper mine, Cadia

The Chilcot mine orebody is a steeply dipping, well defined fissure zone of brecciated andesite, with chalcopyrite in shoots, averaging about 8 per cent copper. Other minerals are bornite, pyrite, hematite, magnetite, quartz and calcite. Pre-ore faults displace the lode channel and are associated with the mineralisation. The ore body is developed by two levels 160 feet in length at 104 and 178 feet depth, and ore is being extracted from a stope between the two levels northeast of the shaft. Water level is a little over 100 feet from the surface. The general pitch of the ore body is about 45 degrees to the northeast. Exploration is recommended of the probable northeast extension of the lode down the pitch, and geophysical investigation to attempt to locate further possible shoots of ore.

East Tennant National Drilling Initiative campaign - summary of field data acquisition

As part of the East Tennant National Drilling Initiative campaign, ten stratigraphic boreholes were drilled in the vicinity of the Barkly Roadhouse, east of Tennant Creek, in the Northern Territory. These holes were designed to test stratigraphic, structural and mineral systems questions in the completely buried and poorly-understood East Tennant region. Drilling was completed during September to December 2020 and was undertaken by MinEx CRC on behalf of Geoscience Australia. This report outlines basic borehole targeting rationale, borehole metadata, and analyses performed immediately following drilling to accompany data available through the Geoscience Australia portal.

First progress report on the geophysical survey of the Astrolabe mineral field, Papua

The areas included in the geophysical survey, namely the Laloki, Moresby-King and Dubuna leases, are among those held by Mandated Alluvials N.L., and lie in the Astrolabe Mineral Field. The positions of the leases held by the Company are shown in Plate G73-1. Laloki, the main producer of copper, is situated 20 miles by road from Port Moresby, near the junction of Sapphire Creek with the Laloki River. The Bureau was requested by Mandated Alluvials to carry out a geophysical survey in the vicinity of the known deposits and in adjacent areas. Both Laloki and Moresby-King mines has been in production up to the time when the war in New Guinea caused a suspension of operations. During the war the mine workings and much of the plant were completely destroyed. When consideration was given to the best method of reopening the mines it was decided that, if a large enough tonnage or ore could be proved sufficiently close to the surface, it would be most profitable to continue open-cut mining, and possibly install a flotation concentrator to avoid the troubles that had always accompanied smelting. The aim of the geophysical survey was, therefore, to locate a body of ore large enough to justify the adoption of these mining and treatment methods.

Antimony supplies

A survey of Australian resources and consumption of antimony, both as metal and antimonial lead, was started later in 1949. This survey had been nearly completed in August 1950, when the Defence Supply Planning Branch of the Department of Supply requested that a survey of the antimony position similar to that for "Graphite" be prepared on their behalf. As the production and marketing of antimony metal is undertaken by one company only in Australia, and of antimonial lead by another, statistics of post-war production, civil consumption and end uses have been readily available.
