Some Conclusions from the Palynological Data of the Neogene of the Mecsek Mountains [antikvár]

Jeta Botanica Academiae Scientiarum Hungaricae, Tomus 16 (1 — 2), pp. 165 — 177 (1970) SOME CONCLUSIONS FROM THE PALYNOLOGICAL DATA OF THE NEOGENE OF THE MECSEK MOUNTAINS By Eszter Nagy hungarian geological institute, budapest (Received May 16, 1969) As the result of palynological investigations conducted by the author on the Neogene of the Mecsek Mountains, this paper deals with the floral changes and relationships and contains the stratigraphical valuation. I The palynological investigation of the Mecsek Neogene covers 12 deep and shallow boreholes and many superficial outcrops. In the course of this work, 398 species became known and many new taxa detected. In the interval between the completion of the monograph and its sending to press some of the new taxa have been published in a number of papers by the author (1963a, b; 1965; 1966; 1968a, b). Owing to the difficulties in the publication of the large monograph, numerous new taxa — described by the author — have first been made known by other authors. Owing to the extent of the monograph, not all of the evaluating chapters could be included in it and presented in the English language either. Therefore the details on the importance of facies-determining plankton organisms and redeposition have been issued in several papers (1962, 1965, 1966, 1967). The author has attempted already in 1962 to reconstruct the paleovegetation from the pollen spectra. More detailed investigations have led to more precise assesments; these are summarized in the following. II In the samples of examined series (Fig. 1) several floral changes can be observed, which, however, are not equivalent to those appearing on the limit of greater units of geological time (periods, epochs). The changes of the geological facies are mostly indicated by the occurring plankton and by the presence of redeposited plant organisms. Conclusions as to floral changes may be drawn from the entity of spore and pollen spectra; the results thus obtained have been combmed harmoniously with the data of lithology and micropaleontology and condensed to floral patterns". The lower, analysable samples from the Szászvár borehole No. 8 examined by the author include the terrestric sequence, the "Szászvár pattern", representing the Lowest Miocene of the Mecsek Mountains. From its spore and pollen spectra the presence of some plant species may be inferred which did not came to light elsewhere in the whole Mecsek Mountains. Such, among the pteridophytes, are Verrucingulatisporites murireticulatus (the spore of a Lycopodium species), Echinatisporites szászvárensis, a Selaginella species, Cicatricosi- Acla Botanica Academiae Scientiarum Hungaricae 16, 1970
