摘　　要：研究智利科皮亚波市瑞康纳达地区不同岩矿石的磁化率,进行对比找出规律。探讨磁化率对寻找铁氧化物铜金型矿床的指示作用,及蚀变岩石的磁化率强度与矿石蚀变类型及含矿性的关系。系统测量这一地区的岩石磁化率,同时进行矿物蚀变填图,圈定蚀变带,提供进一步的找矿信息及标志。In the paper, by studying the magnetic susceptibility of different rocks in Riconada area of Copiapo of Chile and finding the regularity, the authors discussed the instructions role of the magnetic susceptibility in finding iron oxide copper-gold deposit and sought for the relationship between the susceptibility intensity of rock alteration and rock alteration types, ore potentiality. The systematic measurement of rock magnetic susceptibilities has finished in this region. In the same time, the mineral alteration mapping and delineation of alteration zone was carried out too. These will provide further information and indicators for ore finding.
