摘要:

焦家金矿田作为典型破碎蚀变岩型(焦家式)金矿床,探明金资源储量已突破千吨,是目前胶东金矿地球物理探测的焦点区域。针对研究区内矿山开采所带来的工业电磁干扰对CSAMT、MT和SIP等传统电磁勘探方法影响较大的问题,开展了在强工业电磁干扰环境下地球物理方法对胶西北矿集区主要控矿断裂深部响应特征及适用性研究,在焦家金矿田寺庄典型矿段开展微动探测试验工作,通过多重圆台阵变换和不同半径台阵变换的微动探测试验研究,进行空间自相关法分析。结果表明:微动探测视横波速度场特征与主控矿断裂具有耦合关系,通过试验参数优选,可基本实现3 000 m深度区间内焦家断裂带的垂向识别,为今后微动探测方法在胶西北矿集区开展相关勘查工作提供依据。

Abstract:

In recent years,significant advancements in deep prospecting have been achieved within the three principal gold metallogenic belts of Sanshandao,Jiaojia,and Zhaoping,located in the ore concentration area of the northwestern Jiaodong Peninsula.Notably,the Jiaojia gold field exemplifies a typical fractured altered rock type(Jiaojia type) gold deposit.The confirmed gold resource reserves in this area have surpassed one thousand tons,making it a central focus for geophysical exploration within the Jiaodong gold mining region.Historically,geophysical exploration within the study area predominantly relied on electromagnetic methods,including Controlled Source Audio-frequency Magnetotellurics (CSAMT),Magnetotellurics (MT),and Spectral Induced Polarization(SIP).However,these methods were significantly affected by industrial electromagnetic interference resulting from mining activities.To investigate the deep response characteristics and the appli-cability of geophysical methods to the primary ore-controlling faults in northwestern Jiaodong ore concentration area under conditions of strong industrial electromagnetic interference,this study conducts a micro-motion detection test in the representative ore section of Sizhuang within the Jiaojia gold mine field.This study examines the spatial autocorrelation method through micro-motion detection tests involving multiple circular array transformations and varying radius array transformations.The findings indicate a coupling relationship between the apparent shear wave velocity field characteristics of microtremor detection,and the primary ore fracture.By optimizing test parameters,it is feasible to achieve vertical identification of the Jiaojia fault zone within a 3 000 meter depth interval.It provides a basis for the future micro-motion detection method to carry out related exploration work in northwestern Jiaodong ore concentration area.

Key words: micro-tremor detection, SPAC, apparent shear wave velocity, Jiaojia fault, northwestern Jiaodong
