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.
