Seismically-induced structures in the Quaternary sediments of the NE Fennoscandian Shield: Features and age

Abstract

Results of studying secondary seismogenic deformations of the vibrational type (termed "seismites") in loose sediments of the north-eastern Baltic Shield (the Kola region) have been provided. The features, types, formation patterns and age of seismites have been considered. On the basis of previous results the major periods of the region activation in the Holocene have been defined. Criteria of identifying similar structures with widely spread glaciodislocations have been suggested. Results of studying the sections with seismites in certain areas of the region have been provided
