地电化学测量在河台金矿找矿中的试验研究

Tentative investigation of absorption-electricity extraction for exploring gold in Hetai gold deposit

在河台金矿地质研究的基础上,对云西矿区AA′、BB′、CC′3条测线实施了吸附电提取法地电化学测量,通过对测量结果统计分析和地电化学地质剖面图的分析,结果表明,在赋存大规模矿体的9号糜棱岩带(ML-9)上Au含量较低,其原因可能是由于矿体的揭露致使金属离子的淋滤散失或(和)原地上伏土壤遭探采的破坏;而在19号糜棱岩带(ML-19)上Au含量有显著的高峰值。通过分析初步圈定了几个未知异常点,对河台金矿的外围找矿具有借鉴意义。

Based on the detailed research of geological characteristics in Hetai gold deposit, the absorption-electricity extraction method was carried out in the lines AA′, BB′ and CC′ of Yunxi mining erea. Depending on the survey data processing, statistic eigenvalue and section map analysis, the results show that the ML-9 has low Au values, because of the metal ionic losing from exposure veins, and/or the upper soil damaged as a result of exploration and exploitation. While, the Au values of ML-19 are obviously high. Several sealed potential mineralization spots are point out. The application of absorption-electricity extraction technique gives us a reference on gold exploration in marginal fields of Hetai gold deposit.
