The fossil fission track technique has been used for dating Himalayan muscovites of Kathmandu Valley, Nepal. The mean ages obtained for different locations range from 2.5±0.6m.y. to 23±3.3m.y. The uranium concentration has been estimated to be 10-10 atom/atom. The experimental results confirm that the Himalayan orogeny belongs to the Tertiary era.
