摘要
选取了碧口群铜矿床中筏子坝、阳坝和大茅坪三个矿区黄铜矿矿脉中的黄铜矿单矿物样品,通过大量的条件实验及方法研究,用溶解法获取了黄铜矿中的液态包裹体中流体并得出了与实际地质背景一致的Rb-Sr等时线年龄,建立了黄铜矿中液态包裹体Rb-Sr同位素定年的分析方法。
A method is developed for determination of RbSr isotopic dating on liquid inclusions in chalcopyrite.The optimum conditions including chemical separation,best possible spike ratio and mass instrument operation are selected in detail.The proposed method has been applied to the analysis of Rb, Sr isotope in opaque minerals,and has produced good results.
