Kordos-Szakály, Márta: Stratigraphical revision of some Hungarian Badenian-Sarmatian floras
type. All these features speak for the fact that the GREGOR-system, devised in the first place for the Alps cannot be directly applied to the paleoflora of the lowlands of the Carpathian Basin. At the same time, the significant chronological gap (the Pliocene and Upper Miocene in GREGOR' s system equals to the Middle-Upper Miocene in Hungary) indicates that the problem lies not with the stratigraphical correlation but there exists a considerable difference between the rates of evolution of the floras the two areas. That is, a certain stage characteristic of the Alps in the Pliocene existed in Hungary as early as the Sarmatian period. The Eger-Tihamér flora is considerably different from the others, and fairly identical with the flora type eilmp in GREGOR' s system as well as its stratigraphical assignment. SUMMARY The sequence and stratigraphical position of the rich Hungarian "Sarmatian floras" cannot be determined yet, due to a lack of data caused by the still insufficient geological analysis. Determination of the chronology was attempted here using objective methods based on the characteristic features of the paleofloras. A summary of the results is given in Fig. 1. With help of the three methods applied (namely time-distance analysis calculated on the basis of the jointly occurring species, cluster analysis and the GREGOR leaf- and flora-types) the following conclusions were reached: - The oldest (Lower Badenian) flora from Eger-Tihamér is considerably different from that of the other, younger sites. - The materials of the Bertece and Paris-valley near Nógrádszakái are closely related to each other and significantly different from the others as supported by the abundant and usable geological data. - The connections of the Buják flora are uncertain, however the possible right dating for the assemblage is an Upper Badenian, Lower Sarmatian age. - Among the Sarmatian floras in the strict sense, Mikófalva seems older on the basis of the examined data, while the difference between the Balaton-Bánhorváti-Sály floras lies most likely not in chronological, but facies relations. The above data, possibly supplemented by detailed and radiometrical chronological data, might serve as a basis for reconstructing the Hungarian Middle and Upper Miocene floral and climatic evolution. • at Andreanszky , 1955,1959 Kordos-Szakai* 1983 Present paper Gregor zones 1982 V Big. zun locality age locality cluster Gregor method Gregor zones 1982 z < DUgc trop* Str.
