| 摘要: |
| A Study of Characteristics, Genesis and Evolution of Important Geological Relics in the Fanjing Mountain World Natural Heritage site, Guizhou Province |
| The Fanjing Mountain World Natural Heritage site is a Proterozoic rift basin. With the impact of subduction convergence of Proto-Tethys – PaleoTethys - Neo-Tethys as well as the Pacific and the Indian Ocean, it has become a product of multi-period, complex land consolidation and mountain belt evolution. The region is characterized by karst landform surrounded by shallow metamorphic rock mountain landform. There are various types of geological relics and landscapes, including 4 world-class geological relic landscapes. On the basis of previous research, the method of thermal simulation data and structural style was first used to restrict the uplift and evolution of physiognomy in this area. The uplift started intermittently from the end of Cretaceous. Due to the dome structure of Fanjing Mountain and the multiple detachment layers, the planned park shows different rates of denudation, thus laying the foundation of the present landform. Structural analysis and material composition analysis show that Fanjing Mountain has an unique erosion landform of layered and shallow metamorphic rocks, which is believed to be shaped by weathering, denudation and glaciation under the stress shaping dominated by structure. In this paper, the characteristics, genesis and evolution of the study area are also discussed. The Fanjing Mountain World Natural Heritage site has not only varied types of geological remains but also several representative geological sites with global comparative value. It has extremely high scientific and popular science value. |
