| 摘 要： | 采用石英流体包裹体Rb Sr等时线法和磷灰石裂变径迹法对滇西金满铜矿床的成矿时代进行测定。研究结果表明燕山晚期为金满矿床的初始成矿期 ,喜山期是主要成矿时期 ;流体包裹体的Rb Sr法和裂变径迹法测定热液矿床的成矿年龄具有一定的意义 ,但需进一步探讨 ;锶同位素数据为成矿流体来源提供了进一步的证据

| Abstract: | With Rb Sr isochron dating of the fluid inclusions of quartz and apatite fission tracks analysis, this paper tries to determine the metallogenic age of Jinman copper deposit in western Yunnan Province,China.The results show that:(1) The beginning of metallogenic epoch was in Yanshan Movement,and the main metallogenic epoch was in Himalaya Movement.(2) It is not perfect to determine metallogenic age of hydrothermal deposits with Rb Sr isochron dating of fluid inclusions of quartz and apatite fission tracks analysis, but it is worth investigating the two kinds of methods.(3) Strontium isotopes provide further evidence for the sources of ore forming fluid. |
