Molecular Hydrogen from Organic Sources in Geological Systems
We have recently shown that molecular hydrogen generation from organic matter occurs at high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the... -
Multi-stage evolution of the South Australian Craton: Petrological...
To improve the understanding of the formation and evolution of the sub-continental lithospheric mantle (SCLM) underlying the South Australian Craton we have conducted a detailed... -
Isotopes in Economic Geology, Metallogeny and Exploration—An Introduction
Although (Soddy, Nature 92:399–400, 1913) inferred the existence of isotopes early last century, it was not until the discovery of the neutron by (Chadwick, Nature 129:312,... -
Germanium, indium, gallium and cadmium in zinc ores: a mineral system approach
Sphalerite is the main Zn ore mineral and is the primary source of Cd, Ge and In and a minor source of Ga. Owing to a shift from fossil fuel to renewable energy sources, these... -
Light Stable Isotopes (H, B, C, O and S) in Ore Studies—Methods, Theory,...
Variations in the abundances of light stable isotopes, particularly those of hydrogen, boron, carbon, oxygen and sulfur, were essential in developing mineralization models. The... -
A regolith lead isoscape of Australia
We present the first national-scale lead (Pb) isotope maps of Australia based on surface regolith for five isotope ratios, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 207Pb/206Pb,... -
The Paleoproterozoic Trans-Australian Orogen: its magmatic and...
The 2.1─1.79 Ga Trans-Australian and Canadian Trans-Hudson orogens preserve a common record of Himalayan-scale orogenesis and voluminous Cordilleran-style magmatism behind which... -
Geophysical imaging, structural analysis, alteration geochemistry of...
Although oceanic crust covers about 60% of the Earth, relatively little is known of its geology and the processes that have created it. Macquarie Island represents a unique... -
Fieldwork and sampling at Loewe Massif-Amery Oasis
At Loewe Massif and Amery Oasis, samples were taken; - for sediment analysis (XRF geochemistry and grain size) - for geochronology (cosmogenic isotope analysis). The custodian... -
Structure and geochemistry of Macquarie Island oceanic crust
Owing to the fact that the principal investigator died before data were able to be archived, the only available data are in the form of the referenced paper, which is available... -
Exploring for the Future: Integrated geoscience supporting exploration and...
While much of the focus in addressing the challenges of undercover exploration lies in how to directly detect the footprints of buried mineral systems, an equally significant... -
Critical Minerals in Ores - geochemistry database
This database contains geochemical analyses of over 7000 samples collected from or near mineral deposits from 60 countries, compiled by the Critical Minerals Mapping Initiative... -
International Geoscience Collaboration to Support Critical Mineral Discovery
The importance of critical minerals and the need to expand and diversify critical mineral supply chains has been endorsed by the Federal governments of Australia, Canada, and... -
Warrumbungle Volcano: Facies architecture and evolution of a complex shield volcano
We present a new geological map of Warrumbungle Volcano created from volcanic facies field mapping, new geophysical, geochemical, and geochronological data as well as data from... -
Weathering Intensity Model of Australia
Weathering intensity or the degree of weathering is an important characteristic of the earth’s surface that has a significant influence on the chemical and physical properties... -
Australian Groundwater Hydrochemistry Data Collection
Hydrochemistry data for Australian groundwater, including field and laboratory measurements of chemical parameters (electrical conductivity (EC), potential of hydrogen (pH),... -
Seabed Mapping Webinar (Upper Primary), Australia’s Seafloor: What’s on it,...
Geoscience Australia produces a range of educational resources (ga.gov.au/education), including webinars on various geoscientific topics for school children. These webinars are... -
Australian Weathering Intensity Index
A predictive model of weathering intensity or the degree of weathering has been generate over the Australian continent. The model has been generated using the Random Forest... -
How Passive Seismic Surveys Work
This animation shows how passive seismic surveys Work. It is part of a series of Field Activity Technique Engagement Animations. The target audience are the communities that are... -
