Abstract

Cosmogenic isotopes dating is a new technique.It can measure the surface exposure age of geomorphic surface in the age range of 103to 106years.Possible candiates of isotopes used for dating include3He,10Be,21Ne,26A1,36Cl.Cosmogenic isotope concentration in the surface rock is a function of age and erosion rate.This technique has great potential in Geo-surface dating.It can be used to date the glaciation events,volcanic activities,faulting rates,flooding and mud flow events and geomorphological processetc.In a word,in-situ cosmogenic isotope and cosmogenic dating technique is applicable to date the rock surface
that is impossible to be dated by the traditional technique.With the development and the wider application of this technique,geomorphology would be push forward faster.
