摘　　要：定义了该区沉积构造的特性，提出了两种解释接地频域电磁测深的方法。通过正演模型及实测计算证明了这些方法的有效性。结果表明：采用频域电磁测深法对沉积构造的解释和对无物探地质资料的沉积区域进行地质填图和寻找高阻层是一种行之有效的物探方法。Sedimentary seructure features are determined in this area and two metwods interprat earth freauency domainEM sounding are put forward.the effectiveness of these methods have been demonstraeed by forward modelingand calcu-ating field examples. The find results indacate that uesing earth F-D EM sonding to interpretate sedimentary formationfeatures and map sedimeutary areas wyth poor geophysital and geologieal informations or search for resistauce layers isone of the most usefull geoplysicaI teachnigues.
