摘要
在江西河元背地区,针对火山岩型铀矿,采用音频大地电磁法(AMT)与高精度磁法完成了对试验剖面的勘测任务,并把反演结果与已知钻孔结果对比,取得了很好的一致性,准确地指出了断裂的位置,证明了两种方法相结合的有效性。在此基础上完成对其它剖面的测量工作,查明了区内碎斑熔岩和流纹英安岩的分布形态以及断裂构造的位置。
With the aim of exploring volcanic uranium deposit, audio-frequency magnetotelluric method （AMT） and proven high-precision magnetic method were applied to the geophysic survey in Heyuanbei area of Jiangxi province. The inversal derived geophysical survey result was compared with drilling results and was found with satisfied correspondence in precisely pointing out the position of fracture. After verifying the effect of the two methods, orther sections were also surveyed to finding out the distribution patterns of elastoporphyritie lava, rhyolitic dacite and the location of fractures.
