Установлено, что они образуют парагенез деформационных структур пластичных осадков. Рассмотрены возможные гипотезы, объясняющие их формирование, и предложена интерпретация этих структур как палеосейсмодислокаций.</p></abstract><trans-abstract xml:lang="en"><p>On the south-eastern edge of the Baltic Shield in the north-western part of the Onega structure, dislocations previously attributed to slump folds were identified in the sand unit, and their detailed description was carried out. It was established that these formations form a paragenesis of soft sediment deformation structures. Possible hypotheses are considered and a seismogenic model of their formation is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Балтийский щит</kwd><kwd>сейсмиты</kwd><kwd>неустойчивость Рихтмайера-Мешкова</kwd><kwd>неустойчивость Рэлея-Тейлора</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Baltic Shield</kwd><kwd>seismites</kwd><kwd>Richtmyer-Meshkov instability</kwd><kwd>Rayleigh-Taylor instability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования проведены в рамках госзаданий ГИН РАН, ИГЭ РАН, ИФЗ РАН, НИР «Динамика процессов осадочного породообразования (современного и в геологическом прошлом) в различных структурно-геологических условиях и их эволюция» и «Моделирование новейших геодинамических процессов, влияющих на сейсмичность и флюидную проницаемость осадочных толщ» (МГУ имени М.В.
