摘　　要：贵州是沉积岩(尤以中部最为发育)广布的地区,其西部地区为二叠纪玄武岩大面积出露,辉绿岩零星分布,东部地区的东南部为大面积变质岩系裸露,基性—超基性岩散布其中,黔桂接壤的九万大山地区至广西境内见雪峰期巨型花岗岩(基)分布。东北部地区局部出露武陵期花岗岩,它们一同建构了黔郡高原上一幅神秘的地层及岩体分布图,区内已发现大批铝、磷、金、铅锌、锑、汞、煤等矿床,是我国西南地区重要的成矿资源远景区之一。遗憾的是,这里与中低温热液型矿产有关联的中酸性侵入岩分布,全省大部分地区地表未见及,如前所言仅在东北部梵净山(武陵源)一带有微量出露。There are widely-distributed sedimentary rocks in Guizhou, especially in central Guizhou. In western Guizhou, large areas of Permian basalts are exposed at surface together with sporadic diabase, and in the southeastern part of eastern Guizhou, extensively-exposed metamorphic rocks are seen with sporadic basic-uhrabasic rocks in between. Gigantic Xuefengian granite batholiths occur from the Guizhou-Guangxi border area to Guangxi. There locally exist granites of Wuling period in northeastern Guizhou, forming a mysterious distribution map of strata and intrusive bodies on the Yunnan-Guizhou plateau. Large amounts of A1, P, Au, Pb-Zn, Hg and coal deposits have already been discovered, forming one of the important ore prospect areas in Southwest China. Nevertheless, intermediateacid intrusive bodies related to mesothermal-epithermal ore resources are hardly seen at surface in Guizhou Province, with only very few bodies exposed in Fanjingshan （Wulingyuan） area.
