摘要
如何获得准确的成矿年龄是研究热液型金矿床的关键问题,本文综述了热液型金矿床的常用测年方法,如Re Os法、U Pb法、Sm Nd法、Rb Sr法、40 Ar 39 Ar法等,对每种测年方法的适用性和局限性进行了探讨;金矿床的形成是综合地质事件的产物,在金矿定年中要加强对金矿成岩成矿地质背景的研究,测定标志性地质体和矿体的形成年代,使成岩成矿年代互为限定,得到高质量的年代学数据。
How to get accurate metallogenic age is the key to study hydrothermal gold deposits.Dating methods for hydrothermal gold deposits have been reviewed in this paper,such as Re-Os,U-Pb,Sm-Nd,Rb-Sr,Ar-Ar.The applicability and limitation of each dating method have been discussed.It is regarded that the formation of gold deposits is the product of comprehensive geological events.In gold dating,it is necessary to strengthen the study on geological background of diagenesis and mineralization of gold deposits,determine the formation ages of landmark geological bodies and ore bodies,so as to limit the diagenetic and metallogenic ages of each other and obtain high quality chronological data.
