摘　　要：城门山铜矿床位处九瑞铜多金属矿集区南东端,是典型的层控块状硫化物型铜矿床。利用EH4电磁测深清晰的反映地层和低阻体的展布状态,在城门山矿区取得了明显效果,并将这一成果运用到城门山矿区的深部和外围,发现了与成矿相关的电性异常,达到了评价勘探区成矿潜力的目的,也证明了EH4电磁测深对层控硫化物铜矿床是一套高效实用的勘探手段。Chengmenshan copper deposit, located in the southeastem part of JiuRui copper-polymetallic mineralization concentration field, is a typical stratabound massive sulfide copper deposit. EH4 electromagnetic sounding helps the authors to achieve remarkable results in the chengmenshan mining area because it can reflect expansion state of the strata and the low resistance body clearly and this result can be used in the deep and peripheral of Chengmenshan mining area. The paper finds a clearly electric anomaly related to mineralization. It not only achieves the goal of estimating exploration area prospecting potential but also confirms that EH4 electromagnetic sounding is an efficient and practical exploration mathod to investigate stratabound massive sulfide copper deposit.
