Abstract:
      The geotectonics of Guizhou province is composed of the southwestern margin of the upper Yangtze block and the Jiangnan composite orogenic belts, which has undergone four geotectonic cycles. The Wuling geotectonic cycle formed the Puan-Guiyang-Fanjingshan fault,which separated the upper Yangtze block and Jiangnan composite orogenic belt, and gave birth to the Wuling orogenic belt in the northeast of Guizhou, the southeast of Guizhou and the southwest of Guizhou. The Xuefeng-caledonian cycle formed the platform-slope -basin pattern and formed the caledonian orogenic belt in the southeast of Guizhou. The hercynian- indosinian- Yanshan cycle was transformed into the foreland basin of Mesozoic from the intracontinental rift of thelate Paleozoic. The Himalayan-neotectonic cycle entered the intraplate uplift stage and developed the intermontane basins. The multi-period tectonic cycle controlledthe medium-low temperature metallogenic system, dominated by sedimentary deposit, exhalative sedimentary deposit and Sediment-reformed deposit. The Ziyun-Yadu fault in the southwest and western of Guizhou Province deepened into the asthenosphere and caused the “crust-thicken and mantle-whirl-upwell” effect, which caused strong magmatism and large-scale metallogenic materials upwelling,and completed various mineralizations in favorable ore-forming environments and clastic-carbonate rock formation,rendering the southwest of Guizhou - the western of Guizhou being important mineral resources concentration area of Guizhou.
