摘要
地电化学方法作为覆盖区矿产资源勘查的一种有效手段,其原理是在人工外加电场作用下,将近地表介质中呈电活动态的物质选择性地提取,通过研究电提取元素组合、含量分布及异常特征,进而提供找矿信息的一种勘查方法。笔者通过在内蒙古洛恪顿矿区开展地电化学勘查研究,验证了地电化学法在内蒙古东乌旗风成砂覆盖区勘查的有效性,并通过对不同提取时间、不同密度的载体物质等提取条件的对比研究,确定在该区进行地电化学勘查的提取时间为24 h,载体物质选用高密度泡塑。
Geoelectrochemical extraction is an effective method in mineral exploration for overburden covers, the principle of which is to extract nearsurface materials selectively artificial electric field. The exploration method provides prospecting information by studying the electrical extracted element combination、content distribution and anomaly characteristic. Applying this technique to the Luokedun deposit in Inner Mongolia, we proved the effectiveness of geoelectrochemical exploration for aeolian shallow overburden areas. Comparing different extraction time and density carriers, we conclude that the extraction time of 24h and highdensity ploolyform carrier material is the best choice for geoelectrochemical exploration in this area.
