地电化学在隐伏铜镍矿勘查中的应用及异常形成机理探讨
本文从元素迁移角度探讨地电化学异常形成机理。在野外工作的基础上,结合前人成果,通过在金川二矿区采集的地电化学数据结果,以及该地区的相关资料进行综合研究分析,有如下推测：（1）该类地区地电采集的成矿元素的迁移受多个营力多阶段作用,主要由电化学迁移、地气迁移与水动力迁移所主导;（2）电化学迁移的模式会对最终地电数据曲线的形态有所影响,影响的根本因素主要在于矿体形成的电场回路的形态;（3）地电提取的物质是矿体析出并迁移至地表周围所赋存的元素,这些元素在地表呈活动态离子、络合物或超微细颗粒被粘土矿物所吸附。...

| Bibliography: | This paper discusses the formation mechanism of geoelectrochemistry from the migration of elements. In combination with field survey and previous work, this paper analyzes the measured data and related data of mining area No. 11 of the Jinchuan deposit. We obtain the following perceptions ： 1 ） The migration of ore - forming elements collected by geoelectrogchemistry was affected by multiple - stage forces from various factors, dominated by electrochemical migration, geo - gas transfer and hydro - dynamic transportion. 2） The electrochemical migration mode can affect the final curve form of the geoelectrochemical data, of which the fundamental factor lies in the morphology of the electric circuit generated by the ore body. 3 ） The nmterials ex- tracted by geoelectrochemistry are the elements separated out from the ore, which migrated from depth to the surface, and these elements exhibit as active ions, complex and uhrafine particles, which are adsorbed by clay minerals. 11-2043/P LIU Ying-dong1,2,3, ZHANG Bi-mi |
