摘要
位于扬子板块与华夏板块之间的江南造山带上存在着一系列的金矿床,关于这些金矿床的成矿时代前人使用了不同的方法和手段得出的结果也出现了差异,部分结果甚至与地质事实不相符合,因此长期以来江南造山带上的金矿床成矿年龄一直存在争议。笔者在总结前人的基础上分析了争议的存在是由于对地质事实的认识不够以及测年手段的局限性或者不合理所致。
Many gold deposits lie in Jiangnan orogen situated between the Yangtze plate and Cathysia plate. The mineralization ages for these gold deposits has been widely studied by different isotope methods and many debates have remained. On the basis of the summarization of previous studies, this paper emphasized that combination geological development history of gold deposit with appropriate use of isotope dating system should be carefully studied when evaluating any isotopic data set.
