Abstract:In this paper five sources of 36Cl in limestone are theoretically studied, and four characteristics of 36Cl distribution in deep limestone profile are discussed. The sampling method of 36Cl and the AMS analytical technique are described in detail. The surface erosion rate of limestone is Shihuadong area of Beijing is calculated(ε=17.40μm/a). |
