In the basement of the Danube Lowlands, meso- and epi- to anchizonal metamorphites can be distinguished. The subdivision of mesozonal metamorphites into ”Tatric” and ”Veporic” Units (Slovakia) is lacking in composition criteria, and ranging all of them into ”Lower Austroalpine” (Hungary) seems to be groundless. Distinction and correlation of ”Austroalpine” and ”Tatroveporic” mesometamorphites is advisable instead. Epi- to anchizonal metamorphites in Hungary are classified into five units, viz. Szentgotthard Phyllite (analog of the Sausal Series in the basement of the Styrian Basin, Upper Austroalpine?), Bük Dolomite (analog of the Graz Paleozoic, Upper Austroalpine), Vaszar Slate (Paleozoic basement of the Transdanubian Range), Nemeskolta Slate (heterogeneous fill of the dislocation zone of the Raba Line) and Mihalyi Slate. In seismic sections, the Mihalyi Slate emerges from-below Bük Dolomite in the south and mesometamorphites in the north. It is a monotonous carbonate-rich shaly-silty sequence with sporadic tuff and tuffite intercalations. Metamorphic parameters are similar to those of the Rechnitz-Köszeg Penninics but K/Ar white mica ages fall in Early Cretaceous. Correlation of Mihalyi Slates with the Penninics would be possible if we accept that, in the Alpine-Carpathian junction zone, Penninic sediments extend beyond the area of the Tertiary metamorphism. In the basement of the Slovakian Danube Lowlands low-metamorphic rocks on the buried southwestern continuation of the Povazsky Inovec Mts. and in western Ipel Basin may be regarded as possible analogs of the Mihalyi Slate. That would be in harmony with outlining an Ivrea type body in the area since above that body, tectonic units of deepest position — Penninics and even its foot (Kolarovo granites and gneisses?) - are to be expected.
