| 摘 要： | 个旧锡矿床产于个旧东区,是一个以锡铜为主的超大型多金属矿床,具有火山沉积成矿的某些特征,因遭受燕山期花岗岩的叠加改造,区内个旧组卡房段中玄武岩遭受强烈的变质。分析了区内玄武岩的岩石学特征。结果表明,区内的基性岩具有玄武岩的结构构造特征,为玄武岩而非过去认为的辉绿岩。

| Abstract: | Gejiu tin ore deposit, which is located in Gejiu eastern area, is a supersized polymetal ore deposit majored in tin and copper which possesses some characteristics of volcano-sedimentary ore deposit. Because it is superimposed the granit of the Yanshanian epoch, the basalt of Gejiu formation in Middle Triassic Series is metamorphosed intensively. This study researched into the lithological features of basalt in the area. It's proved that the basic rock possesses textural and structural features of basalt, which is basalt, instead of dolerite. |
