An Isotopic Atlas of Australia: Foundational data for integrated geoscience through time and space
Australia has been, and continues to be, a leader in isotope geochronology and geochemistry. While new isotopic data is being produced with ever increasing pace and diversity, there is also a rich legacy of existing high-quality age and isotopic data, most of which have been dispersed across a multitude of journal papers, reports and theses. Where compilations of isotopic data exist, they tend to have been undertaken at variable geographic scale, with variable purpose, format, styles, levels of detail and completeness. Consequently, it has been difficult to visualise or interrogate the collective value of age and isotopic data at continental-scale. Age and isotopic patterns at continental scale can provide intriguing insights into the temporal and chemical evolution of the continent (Fraser et al, 2020).
As national custodian of geoscience data, Geoscience Australia has addressed this challenge by developing an Isotopic Atlas of Australia, which currently (as of November 2020) consists of national-scale coverages of four widely-used age and isotopic data-types:
4008 U-Pb mineral ages from magmatic, metamorphic and sedimentary rocks
2651 Sm-Nd whole-rock analyses, primarily of granites and felsic volcanics
5696 Lu-Hf (136 samples) and 553 O-isotope (24 samples) analyses of zircon
1522 Pb-Pb analyses of ores and ore-related minerals
These isotopic coverages are now freely available as web-services for use and download from the GA Portal. While there is more legacy data to be added, and a never-ending stream of new data constantly emerging, the provision of these national coverages with consistent classification and attribution provides a range of benefits:
vastly reduces duplication of effort in compiling bespoke datasets for specific regions or use-cases
data density is sufficient to reveal meaningful temporal and spatial patterns
a guide to the existence and source of data in areas of interest, and of major data gaps to be addressed in future work
facilitates production of thematic maps from subsets of data. For example, a magmatic age map, or K-Ar mica cooling age map
sample metadata such as lithology and stratigraphic unit is associated with each isotopic result, allowing for further filtering, subsetting and interpretation.
The Isotopic Atlas of Australia will continue to develop via the addition of both new and legacy data to existing coverages, and by the addition of new data coverages from a wider range of isotopic systems and a wider range of geological sample media (e.g. soil, regolith and groundwater).
