激电测深在湖南醴陵金矿激电异常评价中的应用

The Application of IP Sounding Method to IP Anomaly Appraisal in Liling Gold Deposit,Hunan Province

通过探讨激电测深工作在金矿激电异常中的应用效果,并结合以往激电扫面工作,对测区已获得的异常区进行激电测深和进一步的评价,从而确定异常源的位置和埋深,为山地工程提供科学依据。此次研究采用三极激电测深装置,在剖面Ⅰ、Ⅱ及Ⅳ上获得了明显的激电异常。根据视频散率和现场地质情况对异常进行综合分析与解释,预测未知剖面Ⅱ和Ⅳ上矿体赋存的空间位置。通过与已有钻孔资料进行对比,证明本次激电测深工作异常比较可靠,可为醴陵金矿田的勘探工作提供借鉴,为钻探工作提供科学依据。

Through discussing the application effect of IP sounding method in gold deposit,combining with the result of IP intermediate gradient method,we evaluated IP anomalies by the IP sounding method in anomalous areas.The position and depth of mines could be estimated by exploration results,and the sounding results offered scientific bases for the next drilling work.This study adopted three-pole IP sounding method,some obvious IP anomalies had been obtained on the sectionⅠ,Ⅱand Ⅳ.Based on the analyzing and interpreting results of IP anomalies from the apparent amplitude frequency and geological condition,the depth of mines had been forecasted on undiscovered section Ⅱ and Ⅳ.According to comparison of the prospecting results with the known drills,the prospecting results were credible.The sounding results provided reference for further exploration of Liling gold mine,and this investigation method could offer scientific bases for the next drilling work.
