西藏马攸木金矿床金矿化晚阶段含金硫锑铅矿脉石英样品40Ar/39Ar快中子活化法坪年龄为22.46±1.20Ma,坪年龄代表石英的结晶年龄。测试结果表明,马攸木金矿床金的成矿作用可能延续到喜马拉雅中晚期。
The 40Ar / 39Ar fast neutron activation plateau age of the gold-bearing antimony lead pyrites in the late stage of gold mineralization in the Yamu gold deposit in Tibet is 22.46 ± 1.20Ma. The plateau age represents the crystallization age of quartz. The test results show that the gold mineralization of the Ma Yumu gold deposit may extend to the middle and late Himalayas.
