| 摘 要： | 本文采用亚样品取样和Rb/Sr同位素方法对安徽铜陵新桥铜-硫铁-金矿床层状矿体矿石矿物--黄铁矿直接进行Rb-Sr等时线法测定,获得了112.6±7.8Ma的Rb-Sr等时线年龄,它代表了主成矿期成矿作用的时代.结合已有地质资料认为燕山晚期成矿作用在新桥铜-硫铁-金矿床的形成中居重要作用.

| Abstract: | Significant effort has been made in an attempt to date hydrotherrnal activity that generated the Xinqiao Cu-S-Fe-Au deposit in Tongling. New direct Rb-Sr dating of pyrite from the deposit provides direct timing constraints on sulfide and gold mineralization. Pyrite samples yield a Rb-Sr isochron age of 112. 6 + 7. 8Ma. It is concluded that the Xinqiao polymetallic deposit was formed by hydrotherrnal solutions related to late Yanshanian plutonism (110 Ma). Results obtained for the deposit indicate that the Rb-Sr geochronometer has a potential to directly date mineralization in stratabound sulfide deposits. |
