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.
cavities commonly contain calcite alone or in combination with prehnite.
However, research indicates that magmatic modal layers may originate through many other processes (Naslund and McBirney 1996), including, for example, diapiric
ascent and synmagmatic deformation (e.
The seismic profiles contain a section of uniformly bedded sediments, and apparently deep seated diapiric

Evaporites of the Windsor Group form diapiric

Many scientists think that hotspots mark locations where diapiric
convection cells, called mantle "plumes", rise beneath lithospheric plates (Morgan, 1971; Wilson, 1973).
In addition, the shales associated with the rollover faults are commonly over-pressured and diapiric
, adding to structural development in the overburden and increasing the seal on faults.
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.
