Huangling Dome is constitutive of base and cover rocks, which is located in the west edge of Hubei Province, and Hungling Granite is the representative outcrop of the base. Huangling Dome is very important to the formation and evolution of the Yangtze Three Gorges, the formation of structural pattern of Sichan-Jianghan Basins, and also has important effect on security of Yangtze Three Dam. Based on fission track analysis of Hungling Granite, combining with research of terrace characteristic in field, we obtain data of uplift velocity, uplift height and denudation velocity of Huangling Dome since 65Ma: 1)65-7Ma, uplift velocity was 24.6-7.4m/Ma, and uplift height was 1426.8-429.2m; 2)7-0Ma, uplift velocity was 204.1m/Ma, and uplift height was 1428.7m. Especially, uplift velocity increased from 0.058m/Ka to 1.033m/Ka in the course of 0.73Ma to 0.01Ma and mean velocity was 0.134m/Ka, which showed that uplift velocity was slow in the early stage , but increased continuously from then on. Total denudation depth was 2455.5m-1457.9m since 65Ma, and denudation depth was 1028.7m and mean denudation velocity was 0.147mm/a from 7Ma to present. Research results restrict formation time and process of the Yangtze Three Gorges, and prove the Three Gorges is a youthy river valley.
