赣北尖峰坡锡矿床成因类型与成矿模式

Ore genesis and metallogenic model of the Jianfengpo tin deposit in the northern Jiangxi Province

赣北尖峰坡锡矿床位于江西省德安县境内,是彭山矿集区典型的锡矿床之一。在总结矿床地质特征的基础上,结合野外勘查的新地质成果以及前人测试数据上,分析探讨了尖峰坡锡矿的成因类型和成矿模型。研究结果表明:燕山期岩浆热液为本矿床的形成提供了重要的成矿物质来源,指出了尖峰坡矿区下一步找矿方向,为彭山地区的锡多金属矿集区锡铅锌多金属矿化的形成机制提供重要的见解。

The Jianfengpo tin deposit,located in De'an County of Jiangxi Province,is one of the typical tin deposits in the Pengshan ore concentration district.On the basis of summarizing the geological characteristics of the deposit,combined with the new geological results of the field exploration and the previous analysis data,ore genesis and metallogenic model of Jianfengpo tin deposit were analyzed.These results show that the study showed that,Yanshanian magmatic hydrothermal fluid provided an important source of ore-forming materials for this deposit.This study could not only give a useful guide to the next prospecting for Jianfengpo tin deposit,but also provide significant insights to the formation mechanisms of Sn and Pb-Zn polymetallic mineralization in the Pengshan district.
