| 摘 要： | 新疆哈巴河县阿依托汉铜矿位于阿勒泰造山带南缘,紧邻国内著名的阿舍勒大型铜多金属矿,但与其成矿类型有显著区别。在该矿区部署了8条测线,开展了大回线源瞬变电磁数据采集和处理,将反演出的电磁异常与勘探线剖面图对比研究后,预测深部矿体靶位。通过对5线异常解释的钻探验证,结果显示,圈定的低阻异常较好反映了深部低阻体的展布。瞬变电磁反演获得的矿区内电阻率空间分布特征,有助于认识矿(化)体在深部的延伸,为该矿区资源潜力评价提供了依据。

| Abstract: | The Ayituohan copper deposit in Habahe county of Xinjiang is located in the southern margin of the Altai orogenic belt. This deposit is adjacent to the famous Ashele large copper-polymetallic mine, but they have significantly different metallogenic types. This study deployed eight survey lines in the deposit for large loop transient electromagnetic (TEM) data collection and processing, and made comparison between the inversed electromagnetic anomalies and prospecting line profiles to delineate deep orebodies. Drilling verification of the anomalies along the prospecting line No. 5 indicates that the delineated low-resistivity anomalies correspond well to the locations of real orebodies in the sub-surface. The spatial distribution of electric resistivity inferred from TEM can aid to better understand the further extension of mineralized orebodies, and may provide evidence for evaluation of resource potential in this mine area. |
