Determination of tectonic uplift rates of Qinling mountains in central China by fission tracks

Fission track dating of apatite from granites collected at six elevations at Taibai mountains, Qinling range, central China has been carried out. The ages of apatites range from 31.3 to 40.5Ma in sequence consistent with elevations from 1320 to 3760m above sea level. The age–elevation plot suggests the presence of a break in slope, which may represent the base of an exhumed palaeo partial annealing zone (PAZ). Further work on track length measurements is urged for confirmation of this preliminary inference.
