Об активных структурах и вероятных палеосейсмодеформациях в Карелии

Аннотация

Some phenomena concerning possible paleoseismodeformations and active tectonic structures are found in different regions of Karelia. In the North of Karelia the recurring displacements of stream valleys and of other erosional forms take place along the large faults which therefore may be considered as shears. In the same region the rnorphostructures of compression and extension types were analyzed, on the south-west shore of Onega lake hydrolakkolith was found in the lacustrine sediments. All these phenomena may be interpreted as possible paleoseismodislocations.
