Compositional kinetics - Ordovician Goldwyer and Bongabinni formations, Canning Basin, Western 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 Australian source rock and fluids atlas project being undertaken by the Energy Systems Group’s Exploring for the Future (EFTF) program, 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 Ordovician Goldwyer (Dapingian–Darriwilian) Formation and the Bongabinni (Sandbian) Formation, Carribuddy Group, Canning Basin, Western Australia.

The Pioneer mine, Hatches Creek

The Pioneer tungsten-bismuth mine, Hatches Creek, was discovered in 1917 and worked on a small scale from then until a short time after the conclusion of World War I, when production ceased owing to a fall in tungsten prices. Prices rose again in 1937, and exploration resumed. The general geology, ore bodies, and working of the Pioneer mine are discussed in this report.

Electrical resistivity structures and mineral prospectivity from Exploring for the Future AusLAMP data (2016-2019) in northern Australia

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) aims to collect long period magnetotelluric data on a half degree grid across the Australian continent. Data were collected in northern Australia under Geoscience Australia’s Exploring for the Future (EFTF) program from 2016 to 2019. This survey covers the area in south parts of Northern Territory and north western region of Queensland. The project aims to improve understanding of the lithospheric structure in northern Australia. It also provide pre-competitive data and knowledge for selecting mineral prospective areas in the under-explored and covered regions.
This data package contains the preferred resistivity model and associated information for the project. The report provides details for data acquisition, data process and data inversion. The results provide new insights on the lithospheric architecture and mineral potential in the region.

A field summary of the geology of the Barkly Tableland Area

The oldest rocks found in this area are Pre-Cambrian and the youngest are Recent but on the whole the area is one of great stability and not many of the periods of geological time are represented. The Pre-Cambrian are found outcropping round the edge of the basin and for simplicity  in field work have been divided into five divisions. These are Tennant Creek, MacArthur R., Buldiva, Helen Springs, and Barkly Downs. This report provides a field summary of geology by division.

Isotopic Atlas of Australia: Geochronology compilation for Victoria. Version 1.0

This Record documents the efforts of the Geological Survey of Victoria (GSV) and Geoscience Australia (GA) in compiling a geochronology (age) compilation for Victoria, describing both the dataset itself and the process by which it is incorporated into the continental-scale Isotopic Atlas of Australia. The Isotopic Atlas draws together age and isotopic data from across the country and provides visualisations and tools to enable non-experts to extract maximum value from these datasets. Data is added to the Isotopic Atlas in a staged approach with priorities determined by GA- and partner-driven focus regions and research questions. This dataset, which was primarily compiled by GSV and has been supplemented with data compiled by GA during the 2013–2017 Stavely Project, is a foundation for the second phase of the Exploring for the Future initiative over 2020–2024, particularly the Darling-Curnamona-Delamerian Project.
The most current data can be accessed and downloaded from GA’s Geochronology and Isotopes Data Portal.

Mineral deposits of the Palm Beach area, south-east Queensland

The primary aim of the investigation was to determine the reserves and distribution of monazite in the deposits of heavy mineral sands along the East Coast. These deposits contain most of the known world reserves of zircon and rutile for which they are being exploited at various localities, mainly from North Stradbroke Island in Queensland to Ballina in New South Wales. Monazite forms little more than 0.5 per cent of the mixed concentrates, but can be recovered as a by-product from the separation of the other minerals. The monazite forms a source of supply of cerium and also of thorium. The thorium content of the monazite is determined on the basis of its radioactivity. This report gives an account of the field and laboratory work carried out. The results of the laboratory work, which included the separation and examination of minerals, the radiometric determination of quantities of monazite, and the investigation of the thoria content of monazite, are described in this report.

Examination of a supposed bauxite bearing area on Cobourg Peninsula, Northern Territory of Australia

The presence of laterite described as high-silica bauxite at Mt. Roe on Cobourg Peninsula had been reported early in this century by H.Y.L. Brown, who submitted a specimen for analysis. In the absence of information about the mineralogical composition of the rock the chemical analysis alone affords a very incomplete description of the material. It was considered that the rock might be somewhat similar to the commercially valuable high-silica bauxite which occurs in the Netherlands East Indies and Malaya. At the request of the Australian Aluminium Production Commission the writer was instructed to examine the area in the vicinity of Mounts Roe and Bedwell, and to sample and report on any accessible bodies of apparently aluminous laterite. The locality, topography, and general geology of the area are briefly described. Accounts of the laterite occurrence at Mounts Roe, Bedwell, Kura, and Victoria are given. The mineralogical character of the laterite is described.

The occurrence of natural gas at Balmain colliery, Sydney, NSW

Bores sunk at Cremorne in 1891 struck coal at approximately 2802 feet. A company was formed to work the coal, but was refused permission to operate at Cremorne. A site at Balmain was secured, and the Birthday Shaft was sunk to a depth of 2,937 feet between 1897 and 1902. This report provides an overview of the occurrence of natural gas and workings for the period 1897 to 1948. Gas yields, commercial production, leakage problems, and the use of testing to determine the behaviour of gas in the mine are the key subjects that are addressed in this report.

Present status of the search for bauxite in the Northern Territory November, 1949

The presence of bauxite in the Territory was first reported in 1908. This supposed bauxite occurrence at Mounts Roe and Bedwell at the head of Port Essington was examined and sampled by the writer in June, 1949 with negative results. Subsequent to the visit to Port Essington, many specimens of lateritic material from the northern portion of the Territory have been received. Some were collected from inland localities and others from various points on the Arnhem Land coast and adjacent islands. These samples were submitted for visual examination and preliminary testing. The results of these tests, together with the interpretations and conclusions that have been drawn with regard to the search for bauxite, are summarised in this report.

Detonation of explosives, Tadji, New Guinea

This report discusses the proposed detonation of surplus R.A.A.F. bombs at Tadji, New Guinea. A visit was made to the bomb area in March, 1948, to observe the problems involved in detonating the bombs en masse for the purpose of a seismological study of the crustal layering of the island. Various localities in New Guinea, Papua and the neighbouring islands were visited to estimate the practicability of installing temporary seismic stations to record the detonation.

Preliminary report on the King Island scheelite mine (with special reference to proposed boring campaign)

This report is written in advance of the main report in order that a drilling campaign to test the scheelite deposits can be considered immediately. The descriptions are necessarily brief and moreover the report is not accompanied by the full set of plates which will accompany the main report. Present values suggest that the scheelite deposits could be worked on a much larger scale than the present one. The King Island scheelite mines have been operated during two periods, the first being between 1917 and 1920, and the second from 1938 to date. During the first period 67,710 tons of ore were treated for a production of 589 tons of scheelite concentrate, the average yield of concentrate being 0.87 per cent. During the second period 98,305 tons of ore were treated for a production of 627 tons of scheelite concentrate, the average yield on concentrate being 0.64 per cent. In addition and during the latter period 41,260 tons of tailings were re-treated for a production of 52 tons of scheelite concentrate, the average yield being 0.12 per cent. The mine is being worked at present and some 30,000 tons of ore are treated annually for a recovery of 200 tons of scheelite concentrate.

Geological report on Hatches Creek wolfram field

The Hatches Creek wolfram field is situated at the south-east end of the Davenport Ranges approximately 300 miles by road north-north-east of Alice Springs. The present report is written primarily to indicate the amount of ore which may be expected in the principal mines, chiefly by limited development in depth, and to suggest certain lines of prospecting and development which are likely to result in production of ore and which will enable a more confident statement of possibilities to be made at an early date.

The Kuridala copper deposits, Cloncurry district, Queensland

Mapping carried out at Kuridala by C.J. Sullivan and R.S. Matheson during the period June 17th-27th has shown that the ore deposits occur in a major fault (and associated lesser shears). The existence of the fault system is considered to have been proved, and it has been traced, with some interruptions over a distance of three miles. It may extend for many miles beyond the present limits of mapping. The geological information given appears to rule out a number of chances of occurrence at shallow depth, formerly considered likely, and thus is somewhat discouraging. However, the work does indicate that repetition deposits are likely to be present and opens up intriguing possibilities.

Report on bauxite, near Rosevale, county Devon, Tasmania

Five occurrences of ferruginous bauxite near Rosevale were examined and two of them (Nos. 3 and 4) mapped in detail on a scale of 100 feet to 1 inch. It was felt that Areas 3 and 4 which offered some slight chance of successful development should not be abandoned until a few test-pits had been sunk to confirm or disprove the conclusions reached from the surface inspection. Descriptions of the general geology, individual bauxite occurrences, and testing results are given in this report. A locality plan is included.

Evaluation of Geoscience Australia’s Proposed GNSS CORS Antenna Mount Adaptors

Geoscience Australia (GA) designed two types of Global Navigation Satellite Systems (GNSS) antenna mount adaptors which allow antenna north reference marks to be easily and reliably aligned to the true north without changing the height of the antenna with respect to the reference mark. The antenna adaptors evaluated are proposed to be installed on GNSS Continuously Operating Reference Station (CORS) across Australia as new sites are built and commissioned or existing sites upgraded. The purpose of the report is to document the antenna adaptor testing experiments undertaken between 15/09/2021 and 18/10/2021, and determine if the mount adaptors have a significant impact on positioning quality when installed with GNSS antennas on typical GA CORS pillars. Specifically, the mount adaptors were evaluated for their effect on site multipath, position difference, and antenna calibration phase centre variations (PCV) models. Two types of mount adaptors were evaluated, a small adaptor with a diameter of 60 mm and a thickness of 26 mm and a large adaptor with a diameter of 100 mm and a thickness of 26 mm. Both adaptors were fabricated using solid stainless steel. After analysis of observations collected on typical GA tall (~1.5 m) and short (&lt; ~0.2 m) pillars, with and without the adaptors installed, the following conclusions and recommendations can be made: 
a)  The impact of the two types of antenna mount adaptors is small, causing less than 0.02 m change in average multipath based on one week data for L1 and L2 frequencies.
b)  There is around 1.1 mm for the tall pillar and 2.5 mm for the short pillar change in average position difference induced by the two types of adaptors for both horizontal and vertical components based on one week data.
c)  There is no significant impact (less than 1 mm for both L1 and L2 frequencies) on the PCV models induced by small antenna adaptor. 
d)  The small antenna mount adaptor is recommended for tall pillar installations and the large mount adaptor is recommended for short pillar applications.
