中文摘要：

在金矿床中,金、铋常常相伴产出,在金矿体周围存在明显的铋异常,它可作为重要的指示元素。笔者研究了玲珑金矿不同岩石中铋与金含量之间的关系,比较了基岩地球化学剖面中两元素的相关性,采用电子探针分析了主要矿石矿物中铋和金的含量,发现不同类型岩石中铋含量差异明显,铋在矿体中含量远高于围岩,在矿区中铋与金呈幂函数正相关,铋原生晕规模大、衬度高,与金都是以独立矿物相形式存在。在玲珑金矿化探找矿中,铋含量高,与金呈较好的正相关关系,是最佳指示元素之一。

英文摘要：

In gold deposits, Au and Bi are often associated with each other. Around the gold orebody, there exists obvious Bi anomaly, which can serve as an important indicator element. The authors investigated the relationship between Bi and Au content in different rocks within the Linglong gold mine, comparatively studied the correlation of these two elements in the bedrock geochemical profile, and analyzed Bi and Au content in main ore minerals by means of electron microprobe analysis. Some conclusions have been reached ： Bi values are remarkably different in different kinds of rocks, Bi values in the orebody are by far higher than its values in the wall rock, Bi and Au show power function positive correlation in the ore district, Bi primary halo is of large size and high contrast, and both Bi and Au exist as independent minerals. Geochemical prospecting in the Linglong gold mine shows that Bi is of high content, has fairly good positive correlation with Au and thus can serve as one of the best indicator elements.
