Abstract
Six granite samples were collected from six difference elevation locations at the Hua Shan in a main ridge of the Qinling Mountain. Apatite and zircon separated from these six samples were dated by the fission track technique . An assessment of the Cenozoic uplift or exhumation rate was obtained from the altitude difference of sampling samples dated by fission track, and fr om the difference of fission track dates of both apatite and zircon for a s ample. The preliminary results suggest that the beginning of uplift of the Hua Shan was as early as 68.2 MaBP and the uplift rates for different perio ds are 0.02-0.19 mm/a (from the elevation difference) or 0.12-0.16 mm/a (fr om two mineral fission track dates). The average uplift rate is 0.12 mm/a ( from the elevation difference) or 0.14 mm/a (from two mineral fission track dates). The uplift of the Hua Shan might accelerate since (17.8 +/- 2.0) M aBP, and the average uplift rate is about 0.19 mm/a.
