Abstract
<div>Historically, isotopic data are collected at the individual sample level on local- to regional-scale features and are dispersed among decades of both published and unpublished individual academic literature, university theses and geological survey reports, in disparate formats and with widely varying levels of detail. Consequently, it has been difficult to visualise or interrogate the collective value of age and isotopic data at continental-scale. Geoscience Australia’s (GA) continental-scale Isotopic Atlas of Australia (Fraser et al., 2020), breaks this cycle of single-use science by compiling and integrating <strong>multiple radiometric age and isotopic tracer datasets</strong> and making them publicly accessible and useable through GA’s Exploring for the Future (EFTF) Portal.</div><div><br></div><div>The first iteration of a continental-scale Isotopic Atlas of Australia was introduced by Geoscience Australia at the 2019 SGGMP conference in Devonport, Tasmania, through a talk and poster display. In the three years since, progress on this Isotopic Atlas has continued and expanded datasets are now publicly available and downloadable via Geoscience Australia’s Exploring for the Future (EFTF) Geochronology and Isotopes Data Portal. </div>

Lineage
<div>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.</div>
