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
Mechanism of Geoelectrochemistry Anomalies and Application to Prospecting of Buried Cu-Ni Deposits
摘要
Abstract
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.Ⅱ 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 materials extracted 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 ultrafine particles,which are adsorbed by clay minerals.关键词
