Abstract
LA-ICP-MS (laser ablation-inductively coupled plasma-mass spectrometry) has the potential to measure uranium concentration for fission-track (FT) chronometry as an alternative to thermal neutron-induced fission of 235U. This study examines the effect that chemical etching, required to reveal spontaneous fission tracks of 238U, has upon LA-ICP-MS analyses. Uranium concentrations were measured before and after etching for six large gem-quality apatite crystals and six zircon samples - three large crystals and three FT age standards. Comparison of the results shows no significant difference in 238U concentrations measured on the etched and unetched mineral surfaces. The 238U concentrations determined by the LA-ICP-MS provide reasonable FT ages for the zircon age standards, which, with the previously reported LA-ICP-MS apatite FT results, promotes the use of the LA-ICP-MS for FT chronometry. © Geological Society of London 2009.
