摘　　要：为建立深部铁铜矿勘探地球物理模型,以河南省卢氏县八宝山铁铜矿床为例,在合理的成矿预测模型指导下,采用高精度磁测、激电中梯、可控源音频大地电磁测深(CSAMT)等多种综合地球物理方法,对八宝山矿床的深部三维特征和外围区域的含矿性进行初步评价,并通过钻探进行成矿规律的验证。以成矿预测模型为指导,采用综合地球物理勘查对有利成矿部位进行精准刻画,通过钻探对该模型的有效性和可行性进行验证,建立本成矿类型的地球物理勘查模型。In order to establish a geophysical model for deep iron-copper exploration,taking Babaoshan iron-copper deposit in Lushi County,Henan Province as an example,under the guidance of a reasonable metallogenic prediction model,a variety of comprehensive geophysical methods such as high-precision magnetic survey,excitation medium elevation,and controlled source audio magneto earth sounding(CSAMT) were adopted to conduct a preliminary evaluation of the deep three-dimensional characteristics of Babaoshan deposit and the ore-bearing properties of its peripheral areas.The metallogenic regularity is verified by drilling.In this paper,under the guidance of the metallogenic prediction model,the comprehensive geophysical exploration is adopted to depict the favorable metallogenic sites accurately,and the validity and feasibility of the model are verified by drilling so as to establish a geophysical exploration model for this type of mineralization.
