大井铜多金属矿床脉冲瞬变电磁法的直接找矿效果

Direct Detection of Cu-bearing Multimetal Ores by DEEPEM Method in Dajing Area, Lingxi, Inner Mongolia

介绍了使用脉冲瞬变电磁系统(DEEPEM)在大井地区用于寻找低阻覆盖层下工业矿体和评价大功率(MK-Ⅲ)激电异常所取得的主要成果.在未知区找到一处较大的矿带,否定了3个激电异常。

Pulsed transient electromagnetic method (DEEPEM system)has been employed in search of commercial ore deposits beneath the Quaternary overburden of low resistivity in Dajing area, Lingxi, Inner Mongolia. Good exploration results were obtained. An ore belt has been found in a district withoutsufficient geological information and three IP anomalies were tested by this method and are believedto be of other origin not from the ores.
