锆石SHRIMP年龄测定数据处理时系统偏差的避免——标准锆石分段校正的必要性

Avoidance of Systematic Bias of SHRIMP Zircon U-Pb Dating:Necessity of Staged Calibrations

摘要: 介绍了高分辨率、高灵敏度离子微探针质谱计（SHRIMP）锆石原位微区年龄测定中标准锆石的作用、测定方式、数据处理时产生系统偏差的原因及避免系统偏差的办法。以两组实际测定数据处理阐明标准锆石分段校正的可行性和有效性。

Abstract: The functions of standard zircon in SHRIMP U-Pb age determinations are introduced in this paper. The systematic bias in data processing and their avoidance are discussed. The feasibility and effectiveness of staged calibrations are demonstrated with two s
