Description
Australia's national-scale isotopic atlas, expanded by Geoscience Australia, includes over 7500 geological ages and tripled data points for Sm-Nd isotopes. The data, presented at the Australian Earth Sciences Convention in 2026, covers diverse sample media like whole-rocks, floodplain sediments, and K-feldspars. It is designed to illustrate continental-scale geological patterns and support integration with other national geoscience datasets.
Use Cases
Modeling crustal growth and geological processes based on national Sm-Nd and Pb isotope coverages.
Sourcing studies in archaeology and forensics using the national bio-available Sr isotope dataset.
Visualizing the temporal animation of magmatic and mineralisation events across the Australian continent.
Integrating age and isotopic patterns with other national geoscience datasets for cross-disciplinary analysis.
Strengths
Contains over 7500 geological ages, providing a first-pass national geochronology data coverage.
National Sm-Nd isotope coverage has approximately triple the data points relative to its 2013 edition.
Includes diverse sample media such as whole-rocks, K-feldspars, and floodplain sediments, expanding potential applications.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
