Preliminary results of $$^{10}$$Be of the rock samples from the lake terrace of the Lake Pumayum Co in Tibetan Plateau

Nara, Fumiko*; Watanabe, Takahiro   ; Kokubu, Yoko   ; Horiuchi, Kazuho*

In-situ cosmogenic radionuclides have been used to understand earth surface processes, such as the erosion rate and exposure age dating of rocks. This is a preliminary report on in-situ $$^{10}$$Be values measurements by Accelerator Mass Spectrometry (AMS) for rock samples from the shore of the Lake Pumoyum Co in Tibetan plateau. The $$^{10}$$Be concentrations ranged from 5.5-7.5$$times$$10$$^{6}$$ atom/g similar to those of the surface sediments of Lake Pumoyum Co. The calculated erosion rates were 5.2-7.6 mm/kyr, values close to those previously reported by Lal et al. (2003).
