中文摘要：

广西大厂锡多金属矿田中伴生分散元素铟的储量之大为世界所罕见。通过研究该矿田不同矿床、矿体中铟的含量变化特征来探讨矿田内铟的富集规律。研究结果表明：矿田中铟的富集与锡的关系密切；铟的含量存在以龙箱盖岩体为中心向四周逐渐降低，随深度增加而提高的规律。

英文摘要：

There are huge reserve of rare Indium in Dachang polymetallic Tin ore field in Guangxi province. Based on investigation on the variance character of Indium contents in different deposits and ore-bodies of this ore-field, the indium enrichment regularity is discussed. The results showed that indium enrichment has a closely relationship with Tin. And the content of tin is increased with depth and gradually decreased around Longxianggai rock.
