Abstract
Laser-ablation microprobe ICP-MS (LAM-ICP-MS) is rapidly emerging as an exciting new analytical tool in the earth sciences. The paper presents the results of a series of isotopic and trace-element studies of various minerals. Results are presented for Pb/Pb dating of zircon, for which an accuracy of <1% is attainable. For carbonate and mafic minerals of igneous origin, detection limits of 100 ppb and precisions of 2-5% are attained for many trace elements. In general, calibration is possible using synthetic or natural standards; as elemental responses are controlled by the efficiency of the ionization of ablated material in the ICP-plasma, matrix-matched calibrations are not as important as for ion-probe analysis, owing to the efficiency of ionization in the plasma torch. -from Authors
