Abstract

The article discusses tectonic stresses determined in the West Sakhalin terrain using different tectonophysical methods. The reconstruction of the stress field in coal fields in Sakhalin is implemented using the graphical method of orientation finding of stress axes in fractures and faults (at 16 observation points). The supplementary on-site tectonophysical studies made it possible to estimate the preferred orientation of the main slickensides of different kinematics and to reconstruct on this basis the local stress tensors at 53 observation points. The typical stress state of the West Sakhalin terrain is horizontal tension.

根据构造物理研究结果重建萨哈林岛西部的古地应力

摘要本文讨论了使用不同构造物理方法确定的西萨哈林地形构造应力。采用断裂和断层中应力轴的方位图法（16 个观测点）重建了萨哈林煤田的应力场。通过现场构造物理补充研究，可以估算出不同运动学特征的主要滑动层的优先方向，并在此基础上重建 53 个观测点的局部应力张量。西萨哈林地形的典型应力状态是水平拉伸。
