- U-Pb dating method on zircons 锆石U-Pb法测年
- Minerals or altered minerals such as sericite, biotite and K feldspar in the altered wallrocks are selected to be objects of age determination, and the Ar Ar, K Ar, Rb Sr, U Pb isochron dating methods are adopted. 选用矿石或蚀变围岩中的绢云母、黑云母、钾长石等蚀变矿物作为测年对象 ,采用 Ar- Ar、 K- Ar法或 Rb- Sr等时线法测年在目前的技术条件下是经济可行的 ,关键是要保证被测矿物确为蚀变矿物并且纯度较高。 用 U- Pb法测定矿脉中的水热锆石来确定成矿年龄 ,但如何区分继承锆石和水热锆石尚不成熟。
