Abstract

An Isotopic Atlas of Australia (Fraser et al., 2020) provides a convenient visual overview of age and isotopic patterns reflecting geological processes that have led to the current configuration of the Australian continent, including progressive development of continental crust from the mantle. This poster provides example maps produced from compiled data of multiple geochronology and isotopic tracer datasets from this Isotopic Atlas, now publicly available and downloadable via Geoscience Australia’s (GA) Exploring for the Future (EFTF) <a href="https://portal.ga.gov.au/persona/geochronology">Geochronology and Isotopes Data Portal</a> and Mineral Resources Tasmania’s <a href="https://www.mrt.tas.gov.au/mrt_maps/app/list/map">Listmap</a>. These datasets and maps unlock the collective value of several decades of geochronological and isotopic studies conducted across Australia. Compiled geochronology, which commenced with coverage of northern Australia (Jones et al., 2018), is now much more comprehensive across Victoria (Waltenberg et al., 2021) and Tasmania (Jones et al., in press), with New South Wales and South Australia updates well underway. Available data include: Sm–Nd model ages of magmatic rocks; Lu–Hf isotopes from zircon and associated O-isotope data; Pb–Pb isotopes from ore-related minerals such as galena and pyrite; Rb–Sr isotopes from soils; U–Pb ages of magmatic, metamorphic and sedimentary rocks; and K–Ar, Ar–Ar, Re–Os, Rb–Sr and fission-track ages from minerals and whole rocks. <b>To view the associated poster see <a href="https://dx.doi.org/10.26186/147420">eCat 147420</a>.

Lineage

An Isotopic Atlas of Australia consists of compiled data of multiple geochronology and isotopic tracer datasets. This data is available in Geoscience Australia's EFTF (Exploring for the Future) Portal. Available data include Sm–Nd model ages of magmatic rocks; Lu–Hf isotopes from zircon and associated O-isotope data; Pb–Pb isotopes from ore-related minerals such as galena and pyrite; Rb–Sr isotopes from soils; U–Pb ages of magmatic, metamorphic and sedimentary rocks; and K–Ar, Ar–Ar, Re–Os, Rb–Sr and fission-track ages from minerals and whole rocks. Compiled geochronology, which commenced with coverage of northern Australia during EFTF phase 1, is now much more comprehensive across Victoria and Tasmania, with New South Wales and South Australia updates well underway as part of EFTF phase 2. The larger work Record can be found at eCat Record 133772: An Isotopic Atlas of Australia.
