摘要
通过对成矿动力学环境、矿床地质学及同位素年代学分析 ,认为堡子湾金矿形成于印支期[(2 4 5 .9± 0 .3)Ma ,39Ar - 40 Ar],在燕山期 [(14 2 .5± 0 .5 )Ma ,39Ar- 40 Ar]发生矿化叠加 ,并受到花岗斑岩 [(10 5± 0 .6 )Ma ,Rb
The strudy of metallogenic-dynamic environment,geology of ore deposit and isotope chronology shows that Puziwan gold deposit formed in Indosinian Age[(245.9±0.3) Ma, 39 Ar- 40 Ar] and overprinted mineralization in Yanshanian Age [(142.5±0.5) Ma, 39 Ar- 40 Ar],then affected by the intrusion of granite-porphyry [(105±0.6)Ma,Rb-Sr].
