江山市四都镇高塘矿区属剥蚀地貌,水系较为发育,地质构造复杂。该研究区已有大量的地质与地球物理工作,但一直未对深部矿体探测有实质性的进展。利用可控源音频大地电磁法和激发极化对称四极测深法对江山市高塘矿区铜多金属矿进行探测,综合分析了两种物探方法的探测结果,能够准确查明该矿区深部铜多金属矿体的形态、规模等特征。最后通过钻探验证了解译结果的准确性,证明了利用该方法对本区及类似地区进行探矿的可行性。
Jiangtu four town of Gaotang mining area is denuded landform, water system is more developed, complex geological structure. There have been a large number of geological and geophysical work in this area, but no substantial progress has been made in detecting deep ore bodies. Based on the controllable source audio-frequency magnetotelluric method and the excited polarization symmetric quadrupole sounding method, the copper polymetallic deposits in Gaotang ore district of Jiangshan City were probed. The results of two geophysical methods were comprehensively analyzed, which can accurately identify the deep copper Polymetallic ore body morphology, size and other characteristics. At last, the accuracy of interpretation results was verified by drilling, and the feasibility of using this method to prospecting in this area and similar areas was proved.
