| 摘 要： | 世界七大洲最高峰均位于全球或巨型经向或纬向构造带中 ,暗示山脉形成和地球自转之间有内在联系。它们均位于区域弧形构造带弧顶部位 ,弧形构造带成因包括俯冲弧、碰撞弧和伸展弧三类 ,弧形构造弯曲方向与不同类型弧形构造之间有着特定的几何关系。世界七大洲最高峰均与某种具体构造相联系 ,诸如火山构造、推覆构造等 ,反映构造作用在其形成中的意义。它们在新生代期间均发生强烈隆升 ,至今仍有活动。其隆升过程既有构造隆升 ,又有均衡隆升 ,以构造隆升为主。构造隆升中断裂构造、特别是两组断裂复合起着决定作用 ,火山作用对某些高峰的形成有重要意义。

| Abstract: | The highest peaks in the seven continents in the world occupy an important place in the study of global tectonics.They are the best window of study of the continent dynamics.Their formation and evolution are closely bound up with the global climate and environment changes.The highest peaks in the seven continents in the world lie in longitudinal or latitudinal,global or macroscopic mobile belts,suggesting an internal relationship between the mountain building and rotation of the Earth.All the seven peaks are situated in the top of regional arcuate structures.The formation of the arcuate structures is due to subduction,collision or extension,thus curve of the arcuate structures are in different directions.The seven peaks were related to volcano or nappe structure.They were intensively uplifted in Cenozoic,so far they have been under uplift.There were tectonic uplift and isostatic uplift in the process of uplift,and the former was the dominant.The faulted structure in the former,in particular the superimposition of faults of two groups,plays a decisive role,while volcanism plays an important role in the formation of some peaks. |
