APPLICATION OF ELECTROMAGNETIC MEASUREMENT TO GOLD DEPOSIT EXPLORATION IN GREENSCHIST BELT OF WESTERN SHANDONG
-
摘要:
在山东省泰安市周家庄地区金矿勘探中进行电磁测量方法试验, 获得了高分辨率的电性剖面和较可靠的地质解释资料, 经钻探验证发现了隐伏金矿体。测量结果表明, 在岩层深部高电阻率背景下的低值电阻率异常带是寻找金矿化带的有利部位, 低阻异常带的空间展布范围揭示了金矿化带的延伸趋势。
Abstract:In the Zhoujiazhuang gold deposit, Tai' an of Shandong Province, a high-resolution electric profile and reliable geological information have been obtained by using electromagnetic measurement, and hidden gold ores confirmed by drilling proof. The measurements show that the low-resistivity belts under the background of high resistivity in deep part are favourable for formation of gold ore, and the distribution of low-resistance belts reveals the extension trend of gold mineralization.
