新疆鄯善县阿奇山铅锌(铜)矿物化探特征及综合找矿标志

Geochemical and geophysical characteristics and comprehensive prospecting model of the Aqishan Pb-Zn(Cu)deposit in Shanshan,Xinjiang province

通过分析阿奇山铅锌(铜)矿床高精度磁测、激电中梯、高精度重力、对称四极激电测深及化探扫面圈定的物化探异常,推断出物化探异常的原因,并对比了不同物化探找矿方法的有效性。认为高精度磁测找矿效果不明显,激电中梯、高精度重力测量、对称四极激电测深及化探扫面找矿效果较明显。进而总结出区内铅锌(铜)矿勘查的物化探找矿标志,为研究阿奇山铅锌(铜)矿成矿规律及开展地质勘查提供了一定科学依据。

By analyzing the high- precision magnetic survey, induced polarization mid- ladder, high- precision gravity measurement, symmetric quadrupole ionization and geochemical exploration anomalies delineated by geochemical exploration scans in Aqishan's lead- zinc (copper) deposit, the geochemical geochemical anomaly was inferred. The reason for this is to compare the effectiveness of different methods for geochemical exploration. It is considered that high-precision magnetic prospecting has poor prospecting effect, and inducing power ladder, high- precision gravity measurement, symmetric quadrupole induced electrical sounding, and geochemical prospecting have obvious effects. Then, it summarizes the physical and chemical prospecting signs for exploration of lead, zinc and copper in the region. 1)It has typical high- gravity, high- induction and low resistivity. 2)There is an abnormal combination of high intensity, large area Zn, Pb, Cu, Ag, As, and Hg elements. This paper provides a scientific basis for studying the metallogenic regularity and geological exploration of the lead-zinc (copper) ore in the Aqishan.
