| 摘 要： | 结合勘查实践，在系统分析凤太矿田已有地质资料及近年来铅锌、金成矿理论研究成果的基础上，对凤太地区铅锌、金的成矿规律进行了剖析。认为同沉积期的热水活动是最主要的铅锌成矿作用，并形成了金的初始富集，后期构造岩浆活动是金成矿的主要地质作用。同时，依据综合研究和新的铅锌、金找矿信息，通过分析对比凤太地区已知矿床的成矿环境和控矿要素，指出了在凤太地区寻找铅锌、金矿床的找矿预测标志，提出了有关铅锌矿床进一步勘查找矿的5个有利找矿区域及3处隐伏矿的主要勘查靶区和有关金矿床勘查找矿的2个有利找矿区域及4处主要勘查靶区，这为在该矿集区进一步开展铅锌、金矿床的勘查找矿工作提供了依据与方向。

| Abstract: | On the base of analyzing the geological data and metallogenic theory of lead, zinc and gold deposit in Fengxian--Taibai region, the metallogenic regularity of lead, zinc and gold deposit is analyzed, combining with prospecting practice. It is concluded that syndepositional hydrothermal activity is the main mineralizing process of lead and zinc deposit, companying with the initialuenrichment of gold, and that tectonic-magma movement is an important ore forming process of gold deposit. At the same time, according to comprehensive research and new exploration information of lead, zinc and gold deposit, prospecting signs for lead, zinc and gold deposit are pointed out by analyzing and comparing metallogenic environment and ore controlling factors of the above lead, zinc and gold deposits. Therefore, five prospective areas and three exploration targets of lead,zinc deposit and two prospective areas and four exploration targets of gold deposit are divided, which provide foundation and direction for further prospecting and exploration of lead, zinc and gold deposit in the deposit accumulation region. |
