摘要
哈尔达坂铅锌矿床位于西天山别珍套山一带,是新疆近年在前寒武纪地层中发现的规模较大的铅锌矿床之一。介绍了哈尔达坂铅锌矿区的地质特征,从矿石物性、重力测量、高精度磁测和音频大地电磁测等方面分析了哈尔达坂铅锌矿区的物理特征,研究了综合物探方法在哈尔达坂铅锌矿区中的异常特征。综合物探方法在矿体上对应中低阻、高极化、弱磁、高重力组合异常,利用激电、磁法、AMT及重力测量可以有效圈定找矿靶区。
The Haldazan Pb-Zn deposit is located in the Bezhentuoshan area of the Western Tianshan Mountains and is one of the larger Pb-Zn deposits found in the Precambrian strata in Xinjiang in recent years.The geological characteristics of the Hardasaka Pb-Zn deposit are introduced,and the physical characteristics of the Hardasaka Pb-Zn deposit are analyzed in terms of ore physical properties,gravity measurements,high-precision magnetic measurements and audio geomagnetic measurements.The integrated physical prospecting method corresponds to a combination of low and medium resistance,high polarization,weak magnetism and high gravity anomalies on the ore body,and the use of excitation,magnetometry,AMT and gravity measurements can effectively trap the ore target area.
