Abstract：Through surface investigation, sample testing and using previous data, the regional geological survey of 1∶250 000 Chenzhou sheet has studied the overall characteristics of the strata, magmatic rocks and structures, and has summarized the general situation of mineral resources. The regional geological survey has studied the granitic magmatism, the tectonic regime, the deformation dynamic mechanisms, the uplift process of mounts, the tectonic evolution and the tectonic-magmatic-mineralization dynamic mechanisms in Mesozoic, and studied the nature of the Nanhuan-Cambrian basin in southeastern Hunan in the central segment of the Nanling Mountains, and achieved progress as follows: ①the characteristics of major and trace elements suggested that the Nanhuan-Cambrian sandstones from southeastern Hunan were formed in a tectonic setting of passive continental margin; ②the Indosinian Movement in late Middle Triassic in southeastern Hunan was characterized by the intracontinental subduction-convergence controlled by the NWW-SEE compression; we suggested that the sinistral strike-slip motions of the NW-trending basement hidden faults in Indosinian Movement caused N-S-directed lineament in Shuikoushan-Xianghualing area and NWW-directed lineament in Jiangjunmiao-Anren area; we proposed that the trough like folds in Yanling-Rucheng area were formed by the transverse shrinking and flattening of the basement (thick-skin); ③the forming ages of the Indosinain, the Early Yanshanian and the Late Yanshanian granitoids were 233-210 Ma, 174-135 Ma and 154-163 Ma, and their forming tectonic settings were post-collisional setting, post-orogenic setting and intraplate rift setting, respectively; ④through the thermochronological dating study, we revealed that the Meso-Cenozoic uplift process of southeast Hunan could be divided into 4 stages, developing in order of fairly rapid uplift→rapid uplift→slow uplift→rapid uplift; ⑤studying on multiple geological elements, we defined the framework of Mesozoic tectonic evolution in southeastern Hunan and the Hunan-Guangdong-Jiangxi border area, which is of the Early Triassic-early Middle Triassic pre-orogenic stage, the late Middle Triassic-early Middle Jurassic intracontinental orogenic stage, the early Middle Jurassic-Late Jurassic post-orogenic stage and the Cretaceous intraplate rift stage; ⑥we also revealed that the first cause for the fact that the ore-forming capacity of the early Yanshanian granites in southeastern Hunan was far larger than that of the Indosinian granites is the differences in tectonic setting and tectonic regime, and the second cause is the difference in geochemistry of granites; we suggested that the formation of the W-Sn-polymetallic and Pb-Zn-polymetallic deposit assemblage is probably mainly related to such factors as the structure (or thickness) of the lithosphere, intensity of thermal perturbations in the deep interior of the Earth and corresponding scale of magmatism and depth of pluton emplacement.
