Abstract
Quantitative geochronology in Victoria began over 50 years ago with the setting up of a Radiocarbon Dating Laboratory at the Museum of Applied Science in Melbourne. Although this embryonic laboratory struggled throughout its life, and was eventually closed in 1970, it was followed by a new and much stronger phase centred on the development of fission-track dating initially at the University of Melbourne and Rb–Sr dating at La Trobe University. The most recent phase, since about 1990, has involved extensive collaboration between the universities in Melbourne and the joint development of a breadth of additional geochronological facilities and methods, mostly centred on noble-gas mass spectrometry, TIMS and, most recently, multi-collector ICP-MS. Today, geochronology in Victoria based on this extensive arsenal is applied to an ever-widening range of applications across the geological sciences.
