| 坪宝多金属矿田内铅锌银和铜钼钨铋等多金属矿藴藏丰富,矿床类型以岩浆热液成因为主,矿田内多个矿床的分布受断裂构造和燕山期岩浆岩联合控制,研究坪宝多金属矿田的成矿规律、成矿模式,对湘南地区乃至南岭成矿带找矿具有重要意义,为寻找隐伏矿床找矿预测提供依据。随着近年来坪宝矿田内各矿区深部及外围新矿床类型与矿种的发现,人们对区域深部矿床系统结构和分带性有了新的认识。文章在矿床成矿理论的研究和已有矿床成矿模式的基础上,通过对总结不同类型矿床的分带、赋存规律的再认识,进一步完善了已知矿床的成矿模式。从矿床的角度切入放眼矿田,通过单个矿床成矿模式结合典型矿床成矿模式,构建成组合模式；从构造体系控矿延伸至构造成矿系列阶段,并通过认识和总结矿床成矿规律,提高对深部矿床成矿理论的认识,从而实现找矿勘查突破。 |

| Lead, zinc, silver and copper, molybdenum, tungsten, bismuth and other polymetallic ores are rich in Pingbao polymetal ore field, and magmatic hydrothermal genesis is dominant in the genetic types of ore deposits, which has marked prospecting characteristics. Multiple deposits in the ore field are controlled by faulted structure and magmatic rocks together in Yanshan period. Studying the metallogenic models and rules of Pingbao polymetal ore field is significant to prospecting in Southern Hunan Provicne and even Nanling mineralization belt, which will provide the basis for prospecting in concealed ore deposits, the future main battlefield. With discovery of various new types of deposits and minerals in recent years, people have new understanding of the systematical structures and zonation of regional deep deposits. This paper further improves metallogenic models of the known deposits based on reconsideration of the metallogenic models of the known deposits and summarizing of zonation and occurrence rules of different types of deposits. It researches the ore fields from the perspective of deposits, combines metallogenic models of typical deposits with that of single deposits to form integrated models. It extends to the stage of tectonic metallogenic series from tectonic system control, upgrades the understanding of metallogenic theories of deep deposits and instructs prospecting with a breakthrough by understanding and summarizing metallogenic rules of deposits. |
