摘要
河南省北部东西向构造与北东向构造的交汇部位及中部早期东西构造受后期构造的切割或影响部位 ,东西向构造的走向发生变化 ,在平面上呈“弧形”展布 ,从而引起早期矿带走向、厚度等发生变化。由此形成弧形构造控制着早期矿产资源的分布。本文论述了弧形构造的成因 ,阐明了弧形构造的控煤作用 。
In the intersection place of latitudinal structure and notheast trending structure in the northern part of Henan Province and the place of the early east-west trending structure suffered from the dissection and influence of the later structure in the middle part of Henan Province,the strike of east-west structure happened to the outstanding changes.The shape of structural line appearred to be an arc in the plane. From this,the strike and thickness of original ore belt happened to the change,and the distribution of mineral resources in the early stage has been controlled by the arc-shaped structure.In this paper,the authors have discussed the cause of formation of arc-shaped structure,expounded the coal-controlling effect of arc-shaped structure,and analyzed the coal-controlling pattern of arc-shaped structure with the living example.
