| 中文摘要: |
| 大姚六苴铜矿床是楚雄红色盆地中砂(页)岩型铜矿的典型代表.其中小河-石门坎矿段主要分布白垩系,矿体严格受地层控制.根据该矿段7个钻孔揭露的地质信息,总结了剖面上地层颜色的交替变化规律.通过对白垩系不同层位主量元素、微量元素地球化学特征的对比,阐述了浅色层、紫色层元素的变化特征,提出了具有矿化指示意义的元素组合为Cu-Hg-Ag-Sn-Zn-As-Sb-Mn,为深部找矿预测提供了重要依据. |
| 英文摘要: |
| Liuju copper deposit at Daoyao county in the Yunnan province is a typical sandstone - type copper deposit in the Chuxiong red basin. Xiaohe - Shimenkan ore block of Liuju copper deposit is located in the Cretaceous strata, and ore bodies are strictly controlled by the strata. According to geological information from seven drills in the block, color changes in turn of the strata in the profile have been summarized. By comparing of major and trace elements geochemistry in the different Cretaceous horizon, element changes in the light and purple colour horizons are discussed. Association of mineralizing elements of Cu - Hg - Ag - Sn - Zn - As - Sb - Mn has been put forward, can provide important evidence for deep - seated ore exploration prognosis. |
