Abstract In the context of models of mantle circulation beneath the continent, coupled with the subduction of the oceanic lithosphere, a direct link between the kinematics of plate tectonics in the Northwest Pacific Ocean and geodynamic evolution of the Arctic and northeastern Asia in the upper Cretaceous and Cenozoic is revealed. A simple geodynamic explanation is given for the emergence and subsequent termination of Cenozoic shear deformations in the Khatanga–Lomonosov fault zone, which is an important argument favoring the idea of the Lomonosov Ridge as a natural extension of the Eurasian margin to the Arctic (Amerazian) basin.

哈坦加-罗蒙诺索夫断裂带(北极)新生代剪切变形发生和终止的地球动力学成因

摘要 在大陆下地幔环流模型的背景下,加上大洋岩石圈的俯冲,西北太平洋板块构造运动学与上白垩纪和上白垩纪北极和东北亚的地球动力学演化之间存在直接联系。新生代显露。对于哈坦加-罗蒙诺索夫断层带新生代剪切变形的出现和随后的终止,给出了一个简单的地球动力学解释,这是支持罗蒙诺索夫海岭作为欧亚大陆边缘到北极(美洲)的自然延伸的观点的重要论据盆地。
