Cosmogenic 21 Ne exposure dating of young basaltic lava flows from the newer volcanic province, Western Victoria, Australia

Journal Article


Abstract


  • Cosmogenic Ne-21 was utilised to determine exposure ages of young subaerial basaltic lava flows from the Newer Volcanic Province, western Victoria, Australia. The ages (36-53 ka) determined from co-existing cosmogenic Ne-21 and He-3 in olivines separated from basalts are consistent within analytical uncertainties with ages previously determined by cosmogenic Cl-36 exposure dating. This paper illustrates the potential of cosmogenic neon exposure ages in studying the eruption, surface morphology, and erosion history of young volcanic rocks, which are difficult to date using other conventional methods, such as K-Ar or Ar-40/Ar-39 dating. The present study demonstrates that combined cosmogenic He-3 and Ne-21 dating, specifically measured cosmogenic He-3/Ne-21 ratios, on the same samples, is powerful for evaluating the validity of calculated cosmogenic He-3 and Ne-21 surface exposure ages.
