Abstract

Based on the available geological and geodetic data, it has been established that the structures of the Alpine–Himalayan–Indonesian mobile belt are oroclinally (horseshoe-shaped) closed at its western and eastern extremities. In the west, from the Atlantic Ocean, this closure is represented by the Bet–RIF arc and, in the east, from the Pacific Ocean, by the Band and Mindanao arcs. The presence of these closures means there is no structural connection between the mobile belt under discussion and the Atlantic and Pacific oceans, respectively. Thus, the existing plate-tectonic reconstructions, according to which the Tethys paleocean was a wide bay of the Pacific Ocean connected in the west with the Atlantic Ocean (wide Tethys), are in opposition to the facts. The Alpine–Himalayan–Indonesian mobile belt has to be considered an epigeosynclinal rather than an epioceanic structure.

基于宽和窄的特提斯古海洋匹配观点的高山-喜马拉雅-印度尼西亚移动带末端构造和地球动力学模型的澄清

摘要

根据可用的地质和大地测量数据,已经确定,高山-喜马拉雅山-印度尼西亚移动带的结构在其西端和东端是口斜的(马蹄形)。在西部,大西洋沿岸是Bet-RIF弧线,东部是太平洋,以Band和Mindanao弧线为代表。这些封闭的存在意味着所讨论的移动带与大西洋和太平洋之间没有结构上的联系。因此,现有的板块构造重建是事实与事实相反,在该构造重建中,特提斯古海洋是西边与大西洋相连的太平洋大海湾。
