Continuous Bi profile of the East Rongbuk(ER) ice core near Mt.Qomolangma reveals nine major volcanic events since AD 1800.Compared with Volcanic Explosivity Index(VEI),it shows that the concentrations of Bi in the ER ice core can reflect the major volcanic events within the key areas.This provides a good horizon layer for ice core dating,as well as a basis for reconstructing a long sequence of volcanic records from the Qinghai-Xizang(Tibet) Plateau ice cores.
