Keywords: ultrabreccia, seismogenic fault, the Riphean, Rybachy Peninsul
Аnnotation: The manifestation of multistage synsedimentary ultrabrecciation of sedimentary rocks is determined on the Kola Peninsula in the Trollfjorden-Komagelva fault zone delimiting the Riphean complexes of the Rybachy and Sredny Peninsulas. The ultrabreccia fabric features indicate the absence of noticeable displacement of ultrathin material and the in situ occurrence of ultrabreccia in the quasi-isotropic stress field in the weakly lithified water-saturated sediments. The mechanism of ultrabrecciation is apparently the hydraulic shock, analogous to the technogenic hydraulic shock, provoked by seismic events in the Trollfjorden-Komagelva fault zone.
