摘　　要：河南省熊耳山—外方山地区金矿勘查区位于华北陆块南缘,总体构造呈NWW向展布,岩浆活动强烈,地质构造复杂。采用重力测量方法,通过重力异常数据处理,结合已有相关地质资料,对区内马超营断裂的延展情况和隐伏闪长岩展布特征进行了定性推测。圈定了2个布格重力异常分区,划分了32个剩余重力异常,重力异常具有规模大、强度高等特点。推测出Ⅰ级断裂构造5条,Ⅱ级断裂构造26条,圈定出10个以重力成果为主的找矿有利靶区。The gold integrated exploration district at Xiong'ershan-Waifangshan area of Henan Province is located on the southern margin of the North China Block.The overall structure is northwest-westward and the magmatic activity is strong and geological structures are complex.In this paper,the gravity survey method has been applied and the gravity anomaly data processing is carried out,combined with the geological and geophysical information,the extension of Machaoying fault and the concealed diorite are qualitatively inferred out in the area.Two Bouguer gravity anomaly zones are delineated,and 32 residual gravity anomalies are circled out.The gravity anomaly has the characteristics of large scale and high intensity.It is speculated that there are inferred for five fault structures of gradeⅠand 26 fault structures of gradeⅡ,and 10 favorable prospecting target areas are delineated on the basis of gravity result.
