| 摘 要： | 本文通过矿区地层、岩石、矿石和矿物中成矿元素及其伴生元素的分布分配,矿床原生晕的特征,矿石中流、铅同位素的组成以及反映环境特点的元素对比值等方面,结合矿床地质特征,综合论述了该矿床成岩、成矿、成晕的地质—地球化学环境,成矿物质来源,以及后期热液改造元素的活动特点.确认该矿床应属沉积富集为主的层控型矿床.

| Abstract: | Based on the distribution of metallogenic and associated elements in strata, rocks, ores and minerals of the ore district, the primary halos of the deposit, the sulfur and lead isotope compositions of the ores, and retios of elements re flecting environmental characteristics, combined with geological setting of the deposit, this paper summarizes the geological-geochemical environment for the formation of rocks, ores and halos, the material sources for mineralization and behaviours of late-stage hydrothermal elements,indicating evidently that this deposit is of stratabound type dominated by sedimentary enrichment. |
