摘　　要：福建龙岩中甲含锡多金属硫化物磁铁矿矿床中有2种分散元素In、Cd具有工业价值。本文利用常规的显微镜观察、化学分析手段,对该矿床矿石中分散元素铟、镉的含量及富集规律进行了分析研究,结果表明矿床锌(铅)矿化系列铁矿矿石中分散元素铟、镉含量在多金属硫化物型矿石中均超过其作为伴生有用组分的最低工业品位数倍,含量较高。分散元素地球化学特征指示矿床为火山沉积-热液叠加改造成因。该矿床位于南岭多金属成矿带与中国东部环西太平洋大陆边缘多金属成矿带复合部位之闽西-梅州Pb-Zn-Cu-Fe矿多金属成矿带,因此对矿床特征及其中伴(共)生的分散元素富集规律研究具有重要的理论和现实意义。The Zhongjia tin polymetallic sulfide deposit in Longyan city of Fujian Province contains 2 types of industrial dispersed elements In and Cd. This paper studies the content of the dispersed elements In and Cd, and their accumulation in this deposit through conventional microscopic observation and chemical analysis. The result shows that the content of the In and Cd is several times higher than industrial grade of that associated elements in ores of zinc （lead） mineralization series. Dispersed element geochemistry indicates its volcanic sedimentary -hydrothermal superimposed genesis. This de- posit is located in the western Fujian Previnee-Meizhou Pb-Zn-Cu-Fe polymetallic ore belt between the Nanling and West Pacific continental margin poly- metallic metallogenic belt in eastern China. So the studies of features of the deposits and their dispersed element accumulation are of significant theoretical and practical significance.
