某金多金属矿区地表矿化痕迹较多,矿化体和围岩物性差异明显,为了准确查明区内矿体的空间分布以及控矿构造,在该区实施了对称四极装置的激电扫面和EH4连续电导率测深工作.激电测量获得了总体呈NE走向、与地表矿带对应的中高视电阻率(ρ_s)及中高视极化率(η_s)矿化异常带.异常带西窄东宽,矿化集中在测区327°向测线800～1350m处;在与已知矿体对应的η_s-2高极化率激电异常开展的EH4测深工作结果进一步确定了深部成矿潜力:含矿构造延深可达500m,具有低阻异常特征,倾角近直立.激电扫面和EH4测深相结合的综合物探方法在该区达到了查明矿体分布规律、控矿构造的目的,是有效的多金属矿找矿方法之一.
There are many surface mineralization traces in one gold polymetallic deposit, and there are obvious differences in the physical properties between the mineralized deposit and the surrounding rock. In order to accurately identify the spatial distribution of the ore body and the ore-controlling structure in the area, a symmetrical quadrupolar device was implemented in the area Scanning surface and EH4 continuous conductivity sounding.Abnormal mineralization anomalies with medium to high apparent resistivity (ρ_s) and moderate-high apparent polarizability And the width of the core is narrow in the east and the mineralization is concentrated at a depth of 327 ° to the survey line of 800 to 1350 m. Based on the results of EH4 sounding conducted at the η_s-2 high-polarization anomalies corresponding to known ore bodies, the deep Metallogenic potential: The ore-bearing structure can be extended up to 500m in depth with low resistivity anomaly and nearly dip angle.The integrated geophysical prospecting method combined with the EH4 bathymetry and scanning of the surface of the ore reaches the function of determining ore body distribution, The purpose of the tectonic setting is one of the effective methods for ore prospecting of polymetallic deposits.
