中国某些特大型矿床的同位素地球化学研究

超大型矿床因其巨大的经济价值和特殊的产出地质环境与条件历来受到重视。为了查明这些矿床的形成年代，弄清成矿物质来源，了解成矿环境与条件，前人对这些矿床从同位素角度已做了许多研究。近年来，我们对国内若干特大型矿床的同位素特征进行了补充研究。本文结合前人的资料，对这些矿床的同位素研究成果作一概括性总结。

Isotope Geochemical Study of Some Super-Large Ore Deposits in China

Super_large ore deposits have always received great attention due to their high economic value and special geological environments and conditions of occurrence .To ascertain their forming ages, ore material sources and minerogenic environment and conditions, large number of isotopic studies have been carried out on such ore deposits by previous workers. In recent years we have conducted supplementary researches on the isotopic characteristics of some of the super_large ore deposits in China. This paper,combined with previous data,briefly summarizes the results of isotopic studies of these deposits.
