| 中文摘要: |
| 为能够在撒纳龙哇地区有更大发现,在野外地质调查和岩性岩相学研究基础上,运用岩石学、矿物学、矿床学等知识结合岩石地球化学、年代学测得的区内玄武岩锆石U-Pb年龄为(221±2.1)Ma,确定为晚三叠世地层。流体包裹体、H-O-S-Pb同位素地球化学测试等方法,查明及分析了撒纳龙哇矿床的成矿地质体、成矿构造与成矿结构面、成矿作用特征,并建立成矿模式,确定了矿区的矿床成因类型为海相火山岩型铜多金属矿床,为该地区后期找矿工作提供有力的数据支撑。 |

| In order to be able to make a bigger discovery in sanalongwa, on the basis of field geological survey and study of lithology, mineralogy, ore deposit, combined with geochemistry and the zircon U-Pb age, the formation was deteimined to be late Triassic strata. The chronology test result of basalt by zircon U-Pb age was (221±2.1) Ma. Based on the above results and fluid inclusions, H-O-S-Pb isotope geochemical test, this paper found out the mineralization geological bodies, metallogenic structure and structure and metallogenic characteristics, set up the metallogenic model, ensured that the genetic types in this area are Marine volcanic-type copper polymetallic deposits, and provide strong data support for the later exploration work in the region. |
