摘要
在分析研究区域岩浆活动的基础上，认为本区微细粒浸染型金矿的成矿作用与岩浆活动有着较为密切的关系：二者空间关系相互依存；基性侵入岩及火山岩是重要的赋矿岩石或矿化主岩；大量产于基性岩浆岩及火山岩区的金矿床（点）及外围金矿床（点），其成矿作用的矿源和水源都与岩浆活动有关．进一步的找矿应注意基性岩出露地区及其隐伏岩体上部的化探异常．
On the basis of studies of regional magmatism in the Yunnan-Guizhou-Guangxiarea,this paper suggests that there is close relationship between magmatism and micro-grainededisseminated gold mineralizaton: there is obvious mutural dependence in their space,basicintrusive rocks and volcanic rocks are major ore-host rocks or mineralized host rocks; manygold deposits show that ore source material and water source are related to magmatism. Furtherprospecting should pay attention to exposed areas of basic rocks and anomalies of geochemicalexploration on hidden bodies.
