Abstract

Dislocations of loose sandy (probably Holocene) sediments have been distinguished in the southeastern margin of the Baltic Shield in area of the Petrozavodsk Basin. The disjunctive faults have normal fault kinematics. The typical features of their spatial orientation, which coincide with the orientation of latitudinal Paleoproterozoic faults, the valley of the Shuya River, and esker ranges, are described. Possible hypotheses are considered and the model of their formation is presented. The consistent orientation of studied dislocations with ancient faults indicates a tectonic origin and long-lived character of processes, which occur within the southeastern margin of the Baltic Shield of the East European Platform.

波罗的海地盾奥涅加构造全新世砂质沉积物位错起源问题

摘要

在彼得罗扎沃茨克盆地地区波罗的海地盾的东南边缘，发现了松散的沙质（可能是全新世）沉积物的错位。分离断层具有正常的断层运动学。描述了其空间取向的典型特征，与古元古代纬向断裂、舒雅河河谷和埃斯克山脉的取向相吻合。考虑了可能的假设并提出了它们的形成模型。所研究的位错与古代断层的一致方向表明了东欧地台波罗的海地盾东南边缘内发生的构造起源和过程的长期特征。
