Optimization of acquisition and data reduction for LA-ICP-MS analysis of zircon: Tricks and new tools of the trade.
5 septembre 2017 @ 10h00 – 12h00 CET
This talk will include a brief review of the field of U-Pb geochronology of zircon, particularly as it relates to laser ablation ICP-MS analysis thereof. I will describe the analytical hardware at UC Santa Cruz as well as the products of a multi-year effort to improve data acquisition efficiency and quality, data reduction techniques and improved analytical throughput. The effect of standardization with variably radiation standards will be discussed. Finally, I will present a few examples of developing LA-ICP-MS analytical techniques that have the potential to expand the utility of high-throughput zircon U-Pb data for tectonic analysis.
