摘要

For the purpose of calculating the uplifting range of the western Yunnan Plateau, Zhongdian, Baoshan, Jinggu and Jingdong were selected to study the Neogene coal rock. Based on measuring residual depth of strata overlapping on coal strata in field, testing the data of vitrinite reflectance of these samples and determining effective coalification time in laboratory, the authors worked out the maximum paleogeotemperature and the depth of coal rock according to this principle and Bostick’s correlation graph of the three elements. The uplifting range of western Yunnan in Pliocene-Pleistocene was in the range of 1 500～1 700 m from north to south, and the character of overall regular uplifting appeared.
