摘要
文章在了将台以往勘查成果的基础上,通过布置激电中梯和可控源音频大地电磁测深进行异常查证,推断物探异常引起的原因、产状及埋深,查明了矿区岩性、空间分布及其成矿关系,揭示了矿区铁矿层的分布范围、规模、形态和空间位置,根据矿区钻探结果验证了综合地球物理勘探的可行性与有效性,总结了综合物探方法在了将台矿区的找矿效果,为今后相似成矿地区找矿提供了有力依据。
Based on the previous exploration results of Jiangtai,this paper conducts anomaly verification by arranging IP intermediate gradient and controllable source audio-frequency magnetotelluric sounding,infers the causes,occurrence and buried depth of geophysical anomalies,finds out the lithology,spatial distribution and metallogenic relationship of the mining area,and reveals the distribution range,scale,shape and spatial position of the iron ore layer in the mining area.According to the drilling results of the mining area,the feasibility and effectiveness of comprehensive geophysical exploration are verified,and the prospecting effect of the comprehensive geophysical exploration method in Jiangtai mining area is summarized,which provides a strong basis for prospecting in similar metallogenic areas in the future.
