摘　　要：从个旧矿区燕山期花岗岩形成的热源及熔融大地构造、形成花岗岩体的空间来源、复式花岗岩体的形成方式等方面分析,认为用"原地重熔说"能较好地解释个旧矿区花岗岩体的侵位机制,在此基础上对今后的找矿方向提出了建议。On the basis of analyzing of Yanshan granite formation mechanism and tectonic environment and complex granite body formation process,this article has considered that the hypothesis of'In-situ Melting Model'is suitable to explain the intrusive mechanism of granite body in Gejiu ore field.On the basis of geological study,the prospecting suggestion is pointed out for the future work.
