作为地球及天体研究重要计时技术的同位素年代学,近年来在矿产资源勘探工程建设环境保护及某些基本研究课题与相邻学科带动下取得了重大进展。这主要的表现是在一些经典方法(如K-Ar、U-Pb、Rb-Sr)正在日益普及的基础上提出了方法和应用两方面的提高问题;一些应用多年但未完全成熟的方法(如铀系和沉降核类、裂变径迹、Re_Os等)正处于不断改进、日臻完善过程中;与此同时也出现了一批 As an isotopic chronology for the study of important time-keeping techniques for the Earth and celestial bodies, significant progress has been made in recent years in the environmental protection of mineral resources exploration projects and some basic research topics and adjacent disciplines. The main manifestation is that some classical methods (such as K-Ar, U-Pb and Rb-Sr) are being popularized on the basis of the increasing application of methods and applications. Some methods that have been applied for many years but not yet fully developed Such as uranium and subsidence nuclei, fission tracks, Re_Os, etc.) are under continuous improvement and improvement. At the same time, a number of
