Radiogenic isotope geochronology is used to determine the absolute timing of geological events, and is an essential component of geoscience programs at the Geological Survey of Western Australia (GSWA). Geochronology information can be accessed using GeoVIEW.WA, an online interactive mapping system that allows data to be viewed and searched together with other datasets, including Geoscience Australia geochronology data, geological maps, mineral exploration datasets, and more.
Note: the information provided in GeoVIEW.WA is updated regularly.
Alternate formats of geochronology information
GSWA geochronology information can also be obtained:
1. as an annual compilation, the latest of which is complete to June 2012. Purchase this from the eBookshop
2. from the Geochronology Cabinet, which permits direct searching for Geochronology Records by author, rock type, map name, and other attributes
3. as a downloadable ESRI Shape file, Google Earth KML file or MapInfo TAB file, from the Data and Software Centre
U–Pb measurements were conducted using the sensitive high-resolution ion microprobe (SHRIMP II) instruments at the John de Laeter Centre of Mass Spectrometry at Curtin University in Perth, Australia. Lu-Hf isotope measurements were conducted by the ARC National Key Centre for Geochemical Evolution and Metallogeny of Continents (GEMOC) via the ARC Centre of Excellence for Core to Crust Fluid Systems (CCFS) at Macquarie University in Sydney, Australia.
