The diapiric process and glaciotectonic disturbances may have been favoured by altitude differences in the Viru plateau and at the bottom of the Gulf of Finland, which generated the change of load and increase in the pressure on the edge of the ice cover.

The regional geology has been reviewed by Francois (1987) in a comprehensive synthesis, surveyed by Gauthier and Francois (1989) In a following paper, Francois (in de Magnee and Francois, 1988) has laid particular stress on the role played by Roan evaporites and their diapiric ascent in various kinds of tectonic ruptures of the Kundelungu covering, followed by collapse brecciation, to explain peculiarities like the dislocation of the three lower Roan groups in a megabreccia and the cropping out of this megabreccia as fragments, often of large size, which can be mingled with blocks of the Kundelungu Supergroups, as in cases of partial scraping of an anticline flank.
