Geochronology of volcanic landscapes

Cosmogenic nuclides have become indispensable for dating lava flows. Drs Masahiko Honda and Timothy Barrows are dating lavas that have proven too young to date using traditional K/Ar and Ar/Ar techniques. Volcanism has occurred in western Victoria from the Pliocene throughout the Pleistocene. The style of eruption has varied from lava fountains through to explosive maar eruptions. It is likely that volcanism has continued through into the Holocene and will resume again in the future. Overall, the chronology of volcanism is poorly known within the Pleistocene and is being improved by exposure dating.
