为了揭示黄铁矿中分散元素铟的产出状态与富集规律，开展了详细的岩石学、矿物学、地球化学、矿物物理学等方面的研究工作。结果表明，黄铁矿通常与闪锌矿、铁闪锌矿、磁黄铁矿、黄铜矿、方铅矿以及毒砂等共生，主要呈块状构造、浸染状构造、脉状构造、网状构造、梳状构造等，黄铁矿结构主要为交代结构、固溶体结构、自形?半自形粒状结构以及浸染状结构等。黄铁矿中的铟含量介于0.491×10?6~65.1×10?6之间，平均含量为14.38×10?6，然而，该矿田中的高峰矿床黄铁矿铟含量高于大福楼矿床以及铜坑矿床的烟含量，具有更为显著的超常富集特征。另外，黄铁矿中的分散元素镉含量较其余分散元素高，且高峰矿床黄铁矿中的镉矿物同样地比其他矿床富集更为明显。铟与镉以及铟与铊之间均表现出明显的正相关关系，但是，铟与铼之间则为负相关关系，而铟与镓之间不具有显著的正相关或负相关关系。大厂锡石硫化物矿床的主成矿元素锌可能更加有利于分散元素铟的迁移与结晶，对于铟的富集成矿作用至关重要。
To reveal the occurrence state and enrichment regularity of the dispersed element indium in pyrite, the petrology, mineralogy, geochemistry, and mineral physics were researched detailedly. The results suggest that the structure of pyrite is mainly composed of massive structure, disseminated structure, vein structure, reticular structure, comb structure and so on. Generally, the pyrite coexists with sphalerite, marmatite, pyrrhotite, chalcopyrite, galena, and arsenopyrite. And the texture of pyrite primarily consists of the metasomatic texture, solid solution texture, idiomorphic?hypidiomorphic granular texture, and disseminated texture. The content of indium in pyrite ranges from 0.491×10?6 to 65.1×10?6 with an average value of 14.38×10?6. Yet, the indium content in the Gaofeng deposit is higher than that in the Dafulou and Tongkeng deposit, showing a particularly significant supernormal enrichment. Besides, the cadmium content in pyrite is also higher than other dispersed elements, and similarly the abnormal enrichment of cadmium in the Gaofeng deposit is also very significant. An obvious positive correlation exists between In and Cd, or Tl, but a negative correlation between In and Re. It is difficult to find out a positive or negative correlation between In and Ga. The element zinc is of great importance to the enrichment of indium, which can possibly facilitate to the migration and crystallization of dispersed element indium.
