摘    要:本文在总结Rb-Sr等时线定年的基本前提和矿床Rb-Sr等时线定年存在的问题的基础上,综述了铅锌矿床流体包裹体和闪锌矿Rb-Sr等时线定年的研究进展,同时对该定年方法存在的问题进行了简要评述。综合分析表明,Rb-Sr等时线定年(尤其是闪锌矿Rb-Sr等时线定年)为铅锌矿床较理想的直接定年方法,但该定年方法还存在许多理论和技术问题,有待深入研究;铅锌矿床Rb-Sr等时线定年应以深入细致的地质、地球化学研究为基础,定年过程中必须严慎对待样品采集、样品挑选、流体包裹体溶液提取和质谱分析等各个环节。

关 键 词:铅锌矿床  Rb-Sr定年  研究进展

Rb-Sr ISOTOPIC METHOD ON ZINC-LEAD ORE DEPOSITS: A REVIEW
Abstract:In this paper, based on summing up the essential prerequisites and disadvantages of Rb Sr isochron method on zinc lead ore deposits, we sum up the advances on Rb Sr method of fluid inclusions and sphalerites in zinc lead ore deposits, and give a simple commentary on the disadvantages of Rb Sr method. The results show that Rb Sr isochron (especially of sphalerites) is a feasible method for directly dating the zinc lead deposits, but there exist many disadvantages in theory and technique for this method. Careful study of geology and geochemistry must be done before Rb Sr dating of zinc lead deposits. In the Rb Sr dating process, we must pay more attention to samples selecting, picking, fluid inclusion extraction and the analysis at mass spectrometer.
Keywords:Zinc lead ore deposit   Rb Sr dating method   Achievement
