根据作者等近１０多年来在五台山地区的早前寒武纪同位素地质研究，采用单颗粒锆石Ｕ－Ｐｂ、单颗粒结石蒸发Ｐｈ、常规钻石Ｕ．Ｐｈ、全岩Ｐｈ－Ｐｈ、全岩Ｒｂ－Ｓｒ、全岩Ｓｉｎ．Ｎｄ和角门石４０Ａｒ－３９Ａｒ等多种同位素测年方法获得的２７个数据，并以单粒颗锆石Ｕ－Ｐｂ法的９个年龄作为定年的基准，通过与其它同位素测年结果相互印证的综合研究，遂对五台山地区早前寒武纪重大地质事件年代给予了更进一步的限定，同时勾勒出了它的年代构造格架。 Based on the early Precambrian isotopic geology of the authors in the Wutaishan area in the past 10 years and more, single-particle zircon U-Pb, single-grain calculi Ph, and conventional diamond U were used. Ph, whole rock Ph-Ph, whole rock Rb-Sr, whole rock Sin. Nd and angle 40Ar-39Ar dating, and other isotopic dating methods to obtain 27 data, and single-grain zircon U-Pb method of nine age as a benchmark, with other isotope dating results confirmed Comprehensive study, then on the Wutai Mountain Precambrian major geological events dating to give a more limited, at the same time outlined its age structure framework.
