Isotopic Atlas of Australia - An Update (Poster for SGGMP conference 2022)

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the individual sample level on local- to regional-scale features and are dispersed among decades of both published and unpublished individual academic literature, university theses and geological survey reports, in disparate formats and with widely varying levels of detail.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 multiple radiometric age and isotopic tracer datasets and making them publicly accessible and useable through GA’s Exploring for the Future (EFTF) Portal.

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.
