黑龙江下嘎来奥伊河上游铅锌多金属矿航空电磁异常特征及找矿意义
|
摘要
在黑龙江下嘎来奥伊河上游铅锌多金属矿区应用VTEM系统开展航空瞬变电磁、航磁测量,对比分析航空瞬变电磁dB/dt、时间常数、视电阻率及航磁ΔT、反演视磁化率特征与已知矿体地质特征的关系,探索航空瞬变电磁、航磁测量在该类型矿床的探测效果.结果表明航空瞬变电磁、航磁异常与已知矿体吻合度高,在已知铅锌矿体位置,航空瞬变电磁dB/dt呈明显单峰异常,时间常数为高值区,视电阻率为低值区;在已知铁矿体位置,航磁异常明显,反演视磁化率为高值区.总结该矿床航空瞬变电磁、航磁异常特征,建立找矿标志,进行找矿预测,有效地指导了下一步外围找矿工作.本次研究为在大兴安岭高覆盖地区寻找同类多金属矿产提供了一种高效的勘查方法.
Airborne transient electromagnetic and magnetic survey were carried out in the upper reaches of Xiagalai'aoyi river Pb-Zn deposit in Heilongjiang to explore application effect. The comparative analysis is made between airborne transient electromagnetic dB/dt, time constant, apparent resistivity, airborne magnetic ΔT and inverse apparent magnetic susceptibility and the geologic characteristic of known mineral ore bodies. The results show that a single peak anomaly of airborne transient electromagnetic dB/dt, high time constant and low apparent resistivity are above the known Pb-Zn ore bodies. In the iron ore body position, there are obvious aeromagnetic anomalies and high magnetic susceptibility. The metallogenic prediction has been carried out by summarzing airborne electromagnetic and magnetic abnormal characteristics of the deposit,which has effectively guided the geological prospecting work and achieved good results. This study provides an efficient method for exploring similar polymetallic deposits in Daxing'anling which is high coverage area.
