Abstract

Abstract Simultaneously in-situ analysis for more than 25 trace elements and U-Pb and Pb-Pb ages in single zircons using the LAM-ICPMS technique was successfully achieved. The precision and accuracy of analysis are 5-15% for most trace elements, 1-3% for 207Pb/206Pb isotopic ratios, and 2-8% for 206Pb/238U ratios. This combined geochemical and geochronological investigation has significant implications to studying zircons with complicated geological histories.
