| 摘 要： | 阿希金矿脉由里向外具有含金石英脉→硅化带→黄铁绢英岩化的产出特征,其矿区物性测定结果显示,黄铁绢英岩化带电阻率变化范围为60～400Ω·m,其他未蚀变的岩石呈现较高电阻率值,具备了电法勘探的前提条件,即探测富含黄铁矿的黄铁绢英岩化带的分布范围,便可达到寻找金矿矿体目的。本次勘探运用不同电法勘探的特点,通过高密度电法了解浅部矿化信息与矿体平面定位,再利用Stratagem EH4电导率成像及加拿大凤凰公司研制的V系列综合电法进行浅部对比和深部解译,并对其不同方法进行了验证。从勘查区11号线相互佐证的成果图上看,在该勘探线北测深部约400m处,存在一倾角较大的低阻异常,后经钻孔验证,在360m深度见到含金蚀变英安岩及含金石英脉矿体。

| Abstract: | The Ax gold vein has an occurrence feature of auriferous quartz zone → silicified zone → beresitization zone from inner part to outside.The mine area physical property determining results demonstrated that the resistivity variation range is 60-400Ω·m,while other unaltered rocks present higher resistivity values,thus the precondition of electric prospecting has provided.Namely,to cycle out distribution extent of beresitization zone which contains rich pyrite,the target to find gold ore body can be achieved.Particular characters of different electric prospecting methods have exerted in this prospecting.Through high density electric survey to find out shallow part mineralization information and ore body planar positioning,then carried out shallow part correlation and deep part interpretation through Stratagem EH4 conductivity imaging and V series multifunction electric prospecting workstation of the Canadian Phoenix Geophysics,and results from different methods were validated.From No.11 prospecting line resulting image corroborative evidence,a higher inclination angle conductive anomaly existed at about 400m depth,northern part of the line.Afterward,drilling has validated that auriferous altered dacite and auriferous quartz penetrated at 360m depth. |
