摘　　要：豫西熊耳山西北部地区地形切割剧烈,道路崎岖,交通极为不便,激电探测深度要求较大。选择探测深度较大、在复杂地形下便于携带的新型激电仪,在该地区圈定了7个激电异常,在其中4个可能与成矿有关的异常上布置了激电测深工作。综合视幅频率和视电阻率异常、地质情况、物性特征,分析研究区内异常特征与成矿条件,为在该区进一步找矿提供依据。The mining area in northwest Xionger Mountain,western Henan Province is characterized by severely cut terrain,rugged roads,and extremely inconvenient traffic,and its detection depth of induced polarization(IP)is required to be great,so a new type of handy IP instrument with a large detection depth in complex terrain was selected,and 7 IP anomalies were delineated.IP sounding has been arranged on 4 of the anomalies which may be related to mineralization.Based on the abnormal apparent amplitude frequency and apparent resistivity,geological conditions and physical properties,the abnormal characteristics and metallogenic conditions in the area were analyzed to provide a basis for geological prospecting.
