摘　　要：在调整构造学术思想先导下 ,运用遥感 航磁复合分析技术实证东西向古亚洲构造系中南北向横向构造普遍存在的设想 ,以阴山中 西段为研究区 ,发现了多条横向构造带 ,它们在既有的区域构造格局分析与地质图件上少有反映或没有反映。新发现的典型横向构造分析表明 ,控制花岗岩等岩浆活动的横向构造带是“诊断性”控矿构造 ,在走向构造控制矿带展布的情况下 ,其控制矿床的就位 ,具有矿产勘查意义。Under the theory of adjustment structure, the deduction about south north trending transverse confirmed commonly occurring in the east west trending paleo asiatic tectonic system has been certificated through integrated analysis of remote sensing and aeromagnetic data in the paper. More than 10 transverse structures have been found in the middle west segment of Yinshan mountains. Few of them are known in the existing geological maps, and few of them had been considered in some regional geological theories. Analysis to the typical new discovered transverse structures demonstrates that the transverse structure controlling the granitic magma activities is 'diagnosis' ore controlling structure. In the case of strike structure controlled distribution of mineralized belt, the transverse structure controlling the granitic magma activities determines the location of ore deposit, which has very obvious significance for exploration of mineral deposits.
