地质年代学发展历史的简要回顾及前景

简要介绍了基于矿物封闭温度的地质热年代学, 并对多种地质年代学方法, 包括U-Pb 法、 Sm-Nd法、Rb-Sr法、Lu-Hf法、Re-Os法、40Ar /39Ar法、裂变径迹( FT) 测年、(U-Th) /He法、 TIMS铀系法、宇宙成因核素定年(包括14C法等) 和年轻地下水测年(如3H /3He法等) 进行了综合评述。探讨了国际地质年代学百年来和中国20世纪80年代中期以来的发展趋势。根据近期使用情况分析, 认为U - Pb法、40Ar /39Ar法和14C法是目前使用较多的可靠测年方法。应用于山脉隆升和地貌形成的低温热年代学方法及地下水等年轻地质体系的测年, 将是地质年代学发展的重要方向。

Brief review and prospect of geochronological development

Geothermochronology based on mineral closure temperatures and geochronological methods such as U-Pb, Sm-Nd, Rb-Sr, Lu-Hf, Re-Os, 40Ar /39 Ar, FT, (U-Th) /He, TIMS U-series, cosmogenetic nuclide ( including 14C, etc. ) and 3H /3He for young groundwater dating is reviewed in this paper. The developmental trend of international geochronology in recent one hundred years and Chinese geochronology from 1980 s is discussed through the statistics of geochronological documents. According to analyzing the data on usage of geochrono- logical methods, the U-Pb, 40Ar /39Ar and 14C methods are widdy used and reliable geochronometers in recent years. The low temperature thermochronology method which applied in mountain exhumation and geomorphic formation and the dating of young geological body such as ground waterwill be the important developmental trend of geochronology.
