大地电磁测深在四川某工区矿产勘查中的应用研究
|
摘要
大地电磁是一种以天然存在的区域性分布的交变电磁场为场源的电磁勘探方法,其探测深度大,而且不受高阻层屏蔽的影响,对低阻层也反应灵敏,施工也比较简单易行。因此该方法一直备受关注,也得到广泛应用到矿产勘查中,并在国内外都取得了一系列较好的成果。可对深部隐伏矿体进行预测,通过实测数据的分析,解释异常成因。
MT is a kind of natural existence of regional distribution of alternating electromagnetic field as a field source electromagnetic exploration method.the probing depth,and is not affected bythe high resistance shielding effect,low resistance layer has sensitive reaction,construction is relatively simple.So the method has attracted a lot of attention,has been widely applied to the exploration of mineral resource,both domestic and abroad,and made a series of good results.we explain abnormaly interpretation of Genesis by the analyzing the measured data.
