世界七大洲最高峰构造对比

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。

Present-day tectonic movement in the northeastern margin of the Qinghai-Xizang (Tibetan) plateau as revealed by earthquake activity

Characteristics of present-day tectonic movement in the northeastern margin of Qinghai-Xizang plateau (Tibetan) are studied based on earthquake data. Evidence of earthquake activity shows that junctures between blocks in this area consist of complicated deformation zones. Between the Gansu-Qinghai block and Alxa block there is a broad compressive deformation zone, which turns essentially to be a network-like deformation region to the southeast. The Liupanshan region, where the Gansu-Qinghai block contacts the Ordos block, is suffering from NE-SW compressive deformation. Junction zone between the Ordos and Alxa block is a shear zone with sections of variable trend. The northwestern and southeastern marginal region of the Ordos is under NNW-SSE extension. The above characteristics of present-day tectonic deformation of the northeastern Qinghai-Xizang plateau may be attributed to the northeastward squeezing of the plateau and the resistance of the Ordos block, as well as the southeastward extrusion of the plateau materials.
