| 摘 要： | 有证据表明,个旧矿区矿产除与花岗岩密切相关外,基性火山或喷流沉积作用也较明显,变基性火山岩型铜矿的发现及研究增添不少理由。该型Cu矿层状、似层状,赋存于个旧组下段卡房段,矿层多,具同生沉积构造,从而对个旧矿区成矿理论增添新看法。

| Abstract: | According to the evidence,there is not only the clear basic or effusive sedimentation in the Gejiu orefield,but also the close relation with the granite.A lot of reasons are increased by the discovery of Cu deposit of meta-basic volcanic rock type,which are stratified or stratoid,with contemporaneous sedimentary structure,in Kafang Member of the lower member of Gejiu Formation.It is a new study direction of the metallogenetic theory of Gejiu orefield. |
