摘要
航空瞬变电磁法是近年来国际上普遍使用的多金属矿探测方法,具有速度快、效率高、勘探深度大、分辨率高、地形影响小等优点,特别适合工作难度大的浅覆盖区。通过对航空瞬变电磁测量成果与下嘎来奥伊河铅锌矿床资料对比分析,结合已知矿床区域成矿地质背景和地球化学异常信息,在嘎来奥伊地区建立了接触交代(矽卡岩)型铅锌多金属矿床找矿标志,为下一步该区矿产勘查工作提供了技术支撑。
Airborne transient electromagnetic method is widely used in recent years.It has manyadvantages such as in high speed and efficiency,with high exploration depth and resolution in small terrain influence.It is especially suitable for shallow covered areas with large difficulty.Through the analysis of the comparison of airborne transient electromagnetic measurement in data of Xiagalaiaoyi river lead-zinc deposit,we have combined with ore deposit area metallogenic geological background and geochemical anomaly information.We set up the prospecting marks for contact metasomatic lead-zinc polymetallic deposits in Galaiaoyi area,providing technical support for mineral exploration in next area.
