| 摘 要： | 大厂锡多金属矿田是世界上最大的锡多金属矿之一,通过数十年的勘查已取得了丰硕的成果,总结出诸多对找矿行之有效的成矿规律:成矿分带、构造控矿、矿床的层控和时控等规律,指导着大厂矿田的找矿工作,并已取得了丰硕的成果。基于黑水沟—大树脚和羊角尖2个矿区的成矿地质条件,运用大厂矿田矽卡岩型锌铜矿成矿规律,作者对主要赋矿地层特征和层内破碎带等容矿构造以及控矿构造和岩体控矿作用进行研究,分析了与成矿有关的围岩蚀变和物化探异常特征,有针对性地实施钻探工程验证。目前,在两区探获大、中型锌铜矿床各一个。

| Abstract: | s The Dacheng tin polymetalic orefield is one of the largest tin polymetallic orefields in the world. Plentiful achievements have been obtained and a lot of useful ore formation regularities have been summarized after dozens of years' exploration. Metallogenic zone, structural ore-control action, stratabound and time-bound role of ore deposits have been guiding the exploration work in the Dacheng orefield. In recent years, the authors applied these ore formation theories to the exploration of skarn type zinc-copper deposits and obtained good results. Based on studying the ore formation conditions in Heishuigou and Yangjiaojian deposits, the authors investigated the characteristics and shatter zones of the host strata and other ore-bearing structures, probed into the favorable structural and ore-control factors, analyzed the wall rock alteration and geophysical-geochemical anomaly characteristics related to the mineralization, deployed testing drill holes in suitable positions and, as a result, found one large-sized and one medium-sized zinc-copper deposit. |
