英文摘要A zircon U-Pb dating method with a high spatial resolution of 2- to 3-mu m was successfully implemented by using Cameca IMS-1280HR SIMS in this study. Homemade cathode and modified intermediate pole were used to improve the intrinsic performance of duoplasmatron ion source. An O- primary beam with intensity of approximately 3 mu A and stability of 0.68% over 40 minutes was achieved and could be used continuously for more than 240 hours under high current conditions. Under Gaussian illumination mode, a 2- to 3-mu m O- primary beam was obtained with an intensity of approximately 200 pA. Four standard zircons, namely, 91500, Temora, Plesovice, and Qinghu, were dated using the 2- to 3-mu m high spatial resolution U-Pb isotopic analysis, yielding U-Pb ages consistent with their recommended values, within errors. Our work shows that zircon U-Pb dating with high accuracy and spatial resolution can be achieved, on the basis of a series of duoplasmatron modification and instrumental optimization.
