摘　　要：贵州省海西—印支期构造运动产生的陆内裂陷,拉开了黔西地区上地幔岩石圈,从而引发了多期次峨眉山地幔柱玄武岩的喷发和同源异相辉绿岩侵入,带来了与有色金属、黑色金属、贵金属及稀有稀土分散元素等成矿有关的丰富流体。本文基于"全球螺旋大地构造"学说,通过对贵州近年来地质调查成果的综合分析,认为燕山期构造运动造就了贵州地壳东薄西厚的"加厚旋涌"效应,在岩浆活动过程中形成的热液和热动力作用下,地层中成矿物质被活化并初步富集,随着燕山期构造运动及"加厚旋涌"效应的叠加作用,在黔西南-黔西地区形成了贵州重要矿产资源集中区。Intracontinental rifting resulting from hercynian-indosinian tectonic movement in Guizhou Province,it caused the upper mantle lithosphere pull-apart in western Guizhou Province.And it triggered the eruption of the Ermeishan basalts from the mantle plume and the invasion of the homologous and heterogeneous diabase.It brings abundant mineralization fluids associated with nonferrous metals,ferrous metals,precious metals,rare rare earth dispersed elements,etc.Based on the theory of “Global vortex tectonics” and the comprehensive analysis of geological survey results in Guizhou in recent years,this paper considers that the Yanshanian tectonic movement resulted in the “Thickening swirl upwelling” effect of thin crust in the East and thick crust in the west of Guizhou Province.Under the action of the hydrothermal and thermal dynamic formed by magmatic activity,the ore-forming materials from stratum were activated and enriched.Along with the Yanshanian tectonic movement and the superimposition “Thickening swirl upwelling” effect,an important mineral resource concentration area was formed in the southwest and west of Guizhou Province.
