ОТРАЖЕНИЕ ГРАНИТО-ГНЕЙСОВЫХ КУПОЛОВ СЕВЕРНОГО ПРИЛАДОЖЬЯ В СОВРЕМЕННОМ РЕЛЬЕФЕ

We analyzed the relief of granite-gneiss domes Havus, Kokkasel’skij, Riekka, Sortaval’skij and Iokirantskij in the Northern Ladoga Lake region. It is established, that the subisometric Havus and Kokkasel’skij granite-gneiss domes are projected in relief as elevations; within them a series of concentric lineaments is revealed according to the pattern of the distribution of relief development coefficients. Domes, which have a more complicated shape are both areas of elevation (Riekka, Iokirantskij), and t heregions of subsidence (Sortaval’skij dome). Computer modeling suggested that complicated relationships between the geological structures and modern relief are to a large extent conditioned by neotectonic activation of Archean domes under the northwest compression.
