[SCG41-01] AusGeochem: A global data platform for community low-temperature thermochronology
★Invited Papers
Keywords:Thermochronology, Community platform, Data repository, Fission track, (U-Th)/He
Low-temperature thermochronology is a powerful tool for constraining the thermal evolution of the upper crust with application to geodynamics, continental crustal evolution, natural resource formation and preservation, and landscape evolution. Like most geoscience data, thermochronology information is most valuable when combined with information from multiple isotopic and mineral systems and integrated with existing regional and contextual data to provide greater insights to the tectonothermal evolution. To efficiently integrate and reuse such data beyond a research group level, however, requires consistent reporting standards, data infrastructure and subsequent community adoption of such systems.
Here we present the open-access AusGeochem platform, a community resource for geoscientists from around the world to freely store, disseminate, explore, publish and reuse Earth science data ranging from sample information to a broad variety of geochronometers and geochemical systems, including thermochronology. AusGeochem provides a novel tool for thermochronology data (such as fission track, (U-Th)/He and thermal history models), allowing thermochronology data from both the user, collaborators and published community resources to be viewed spatially and in the context of geosample metadata (e.g. lithological and mineralogical information) and other geochemical analyses or isotopic systems. Through integration of plate tectonic reconstruction models this spatial context can be extended to visualising sample data back through deep time in their paleogeographic positions, directly within AusGeochem.
The AusGeochem system provides detailed, structured schemas for fission track and (U-Th)/He (meta-)data, to capture complete datasets required for confident data interpretation and reuse, allowing community datasets to be readily explored in new and powerful ways. The platform has a range of real-time data interrogation tools, including the ability to produce live age histograms, radial and scatter plots (e.g., boomerang or age versus elevation), swath profiles, and spatial data interpolations. Data schemas also extend to capture the thermal history models generated from low-temperature data, and allow visualisation of paleotemperature or periods of cooling or heating for extensive compound datasets across a large region of interest. Furthermore, the platform’s Open Rest Application Programming Interface (API) enables external software components, operating systems and applications to access and interact with AusGeochem-hosted data to facilitate a variety of tasks that include automatic (meta-)data upload, automated data retrieval, and the incorporation of additional data synthesis functions and machine learning algorithms. Current examples of API utilisation include the drag-and-drop upload of fission track count and length data upload from FastTracks (version 3.3.5 and above) and exports from QTQt thermal modelling software, and direct export of platform hosted data to IsoplotR.
Scientists from around the world are encouraged to freely register to use AusGeochem for low-temperature thermochronology and other Earth science data at https://ausgeochem.auscope.org.au
