摘　　要：为了解黄家营子铜矿东区成矿前景,指导进一步探矿工作,对勘察区进行了详细地质调查,发现地表已知矿脉明显受断裂构造控制。该矿地表探槽控制20余米,为进一步了解已知矿脉向地下深部延伸情况,尝试采用具有高分辨率特征的EH4电磁成像系统来解析区内深部地质结构、矿化异常体特征。在EH4电磁测深断面图上可以看出已知控矿断裂向下延伸400余米,但异常呈串珠状。综合研究表明,该矿点具有很好的赋矿条件,但矿化强度需通过进一步的工作加以证实,同时证实了EH4电磁成像系统解析深部地质构造的有效性。In order to understand the mineralization prospect of the east area of Huangjiayingzi copper deposit and guide the further ore prospecting work, detailed geological investigation was made in the target area. It was found that the known surface ore vein was evidently controlled by faulted structure. This surface exploratory trench controlled more than 20meters. To further know the vein downward extension, we tried to use high resolution EH4 electromagnetic image system to analyze the deep geological structure and mineral abnormalities. It can be seen from the EH4 electromagnetic sounding sectional map that the ore-controlling fault has extended downward for about over 400 meters but the abnormalities are discontinuous. The comprehensive research indicates that this mineral occurrence has very good ore occurrence conditions, but the mineralization intensity has to be further verified. The effectiveness of analyzing the geological structure at depth by EH4 electromagnetic imaging system is thus verified.
