| 摘 要： | 年代确定在地学中得到广泛应用.而作为地史学中重要的组成部分，年代确定为地质时期中地球岩石圈在时间上发展和演变提供了重要的时间约束.本文综述了四种定年方法：即古生物法；古地磁法；同位素法和地球物理法.随着地球物理的探测技术的发展，地球内部精细结构得到揭示.我们认为，应用地球物理资料确定年龄将可以弥补其它方法的缺陷，可能为地球内部三维岩石定年提供支撑.

| Abstract: | There are many applications of dating in Geosciences.As an important part of historical geology,the age shows the history of lithosphere development and evolution of geological time,and dating plays an important role in it.There are four methods in dating,which include: the paleontology method;the archeomagnetism method;the isotopic method;the geophysical method.Along with the development of geophysical exploration technique and more fine structure underneath having been revealed,we think that the dating method utilizing geophysical data which will make up other methods deficiencies will bring foundation for 3-D rock dating. |
