| 摘 要： | 根据贵州所处大地构造位置，在前人划分的扬子陆块、江南造山带和右江造山带构造单元的基础上，结合水系沉积物测量区域化探扫面成果，划分出四川盆地边缘SiO2-Na2O高背景地球化学区，黔北隆起F－CaO-MgO及亲基性元素高背景地球化学区，黔西断陷Au-As-Sb-Cu-Pb-Zn-Fe3O3亲硫元素及亲基性元素强聚集地球化学区，黔南台陷Cd-Hg-Sb-Ag-SiO2高背景地球化学区，江南造山带Ba-Ag-Al2O3－K2O-Na2O高背景地球化学区和右江造山带B－Au-Sb-SiO2高背景地球化学区等6个地球化学区。结合有关资料还在阐述各区地球化学特征的基础上，探讨了它们的科学意义。

| Abstract: | The six geochemical regions, including the high background of SiO 2-Na 2O in the margin of Sichuan Basin, the high background of femaphile elements and F-CaO-MgO in the uplifts of north Guizhou, the strong concentration of sulphophile elements and femaphile elements (Au-As-Sb-Cu-Pb-Zn-Fe 2O 3) in the fault subsidence of west Guizhou, the high background of Cd-Hg-Sb-Ag-SiO 2 in the platform subsidence of south Guizhou, the high background of Ba-Ag-Al 2O 3-K 2O-Na 2O in the Jiangnan orogenic belt and the high background of B-Au-Sb-SiO 2 in the Youjiang orogenic belt, are divided according to the geotectonic location of Guizhou province, and the structural elements of the Yangzi landmass, the Jiangnan orogenic belt and the Youjiang orogenic belt combing with the results of regional geochemical exploration of drainage sediments. In this paper, the scientific significance and suggestions in exploration are dealt with. |
