The present research extended to the Mecsek Mts., the Máramaros flishbelt, the Slavonian inselbergs as well as to northern Slovenia (one of the marginal zones of the Tisza (Tisia) unit) where associated with younger Tertiary horizontal displacements, clockwise palaeomagnetic rotations were observed. In the Mecsek Mts., ignimbrite occurrences bordering the Neogene sedimentary trough on the north, show a counter clockwise rotation of approximately 60°, while the younger sediments of the trough did not rotate. A number of sedimentary sampling localities occuring in the main body of the mountains shows clockwise rotation of similar magnitude as the magmatites of Cretaceous and younger age. No rotation was detected for upper Pannonian sediments outside the mountainous area. In the Slavonian inselbergs, counter clockwise rotations of various angles were observed, while none of the flish occurrences of Máramaros possessed fossil magnetization. The results of the present research allows the conclusion that during the Tertiary the various subunits of Tisia were not yet welded together i.e. the rigid Tisia must have formed later.
