Abstract

Mt. Sanqingshan Geopark in Jiangxi is famous for its granite peak-forest landforms in the world. Low temperature thermal-chronology is used to analyze the uplifting and denudation process of Mt. Sanqingshan in the paper. The fission track ages can be divided into three groups, which can be related to the uplifting-denudation processes involved in forming ancient multilevel denudation planes. Mt. Sanqingshan underwent four stages of thermal evolution, approximately 90Ma to 60Ma, 60Ma to 40Ma, 40Ma to 15Ma, 15Ma to the present. The corresponding cooling rates are 1.95øC/Ma, 1.17øC/Ma, 0.35øC/Ma, 3.72øC/Ma, with the average cooling rate of 1.81øC/Ma. The last stage is significantly faster than the other three stages, reflecting the faster uplifting of Mt. Sanqingshan under the new tectonic movement. The average uplifting rate in Mt. Sanqingshan is 0.052mm/a, and the average denudation rate is 0.047 mm/a, with the gap of 0.005mm/a. The average uplifting amount is 3500m, denudation 2500m, since the average apatite fission track age - 56Ma. The gap is very close to the average elevation in Mt. Sanqingshan. This is the process from the magma emplacement 6km underground to present medium-sized mountain. These features are consistent with geomorphology stages and geological evidences. Thermal-chronology has important constraint for different stages of granite landforms.
