| 摘 要： | 斯匹次卑尔根岛是斯瓦尔巴特群岛中最大的岛屿,具有较全的地质时代记录、反映多次构造运动的构造现象。本文从构造组合的观点,对斯匹次卑尔根岛的构造划分为东西向、南北向、北北西向三组方向,它们反映了本区自元古代以来至少经历了三次不同方向的构造应力场作用。

| Abstract: | Spitsbergen is the largest island with representatives of most geological ages and structures representing most tectonic events in Svalbard. In order to recognize the tectonic history, it is important to determine the mechanical nature of faults. From the view of tectonic association, the structures developed in Spitsbergen can be grouped into three directions of principal strain: SN, EW and NNW compressed zones. They have been produced by three tectonic stress fields which indicated compression EW, SN and NWW-SEE directions respectively in this region since Proterozoic Era. |
