Abstract

In the course of seismic reflection measurements for studying the lithosphere and asthenosphere deep displacement zones were found beneath the Szolnok-Máramaros Flysch Belt, the Derecske Basin, further beneath the area of the Békés Basin and the Hódmezōvásárhely-Makó Graben cutting through the crust and the upper part of the lithospheric mantle. Within the lithosphere several ductile zones can be assumed one under the other in which slow stress changes lasting for millions of years are causing "plastic" flow or "creep" of solid rocks. In the course of the described investigations it was established by us that the deep displacement zones penetrating as deep as the mantle lithosphere might have formed through localized shearing. In the Szolnok-Máramaros Flysch Belt along the displacement zone system determined in the course of the described investigations dislocations of extensional type taking place at the end of Senonian - beginning of Paleogene may have formed the sedimentary basin of the Szolnok Flysch. The origin of the row of depressions protruding from the SE part of the Hungarian Plain into the Transylvanian Ore Mountain was promoted by two displacement zone systems almost perpendicular to one another.
