江西冷水坑矿田银铅锌矿床特征及成矿模式探讨

摘要

江西贵溪冷水坑矿田是国家级银资源基地.本文在系统研究冷水坑矿田成矿地质条件、矿床地质特征的基础上,从分析主要控矿因素和成矿系统人手,初步建立了冷水坑矿田成矿模式.认为冷水坑矿田矿床类型主要有两类:即斑岩型矿床和层控叠生型矿床.结合矿田成矿特征和成矿模式,进行了成矿预测,提出冷水坑矿田小源区、麻地-燕山区和闽坑-岭西铅锌区3个成矿预测区具有较好的找矿远景,为进一步开展找矿工作提供了依据.%The metallogenic model for the silver-lead-zinc deposits in the Lengshuikeng ore field, Jiangxi is constructed on the basis of geology, ore-controlling factors and mineralization systems of the Lengshuikeng ore field. The ore deposits in the ore field may be classified into two types; porphyry-type and stacked stratabound-type ore deposits. The metallogenic prognosis is also made in the light of the metallogenic model presented in this study, and three exploration prospects are delineated, including the Xiaoyuan, Madi-Yanshan and Minkeng-Lingxi lead-zinc mining districts favourable for further exploration.
