Palynologic Investigations on the lower eocene layers in the surrounding country of Iszkaszentgyörgy I. (dedikált példány) [antikvár]

PALYNOLOGIC INVESTIGATIONS ON THE LOWER EOCENE LAYERS IN THE SURROUNDING COUNTRY OF ISZKASZENTGYÖRGY Iby M. Kedves Institut for Botany of the University, Szeged, Hungary (Dir.: Prof. Dr. P. Greguss)IntroductionIn the course of two previous palynologie investigations (3,4) I came to the conclusion that the Hungarian Lower Eocene (Sparnat) flora can be divided into several districts. The observations made in the basin of Tatabánya (5) have led in this respect to interesting results, and have urged me on to study other territories on the same principles for maximum possible information. It seemed to me essential to investigate palynologically the Lower Eocene coal deposit overlying the bauxite in the country surrounding Iszkaszeatgyörgy. . I am much obliged to Dr. B. Molnár, and to the Board of Directors of the Bauxite-Mines of the comitat Fejér who supplied me with material.For the geognosy of the surrounding country of Fehérvárcsurgó, Isztmér, and Iszkaszentgyörgy the statements of Gőbel (2) are decisive. Accordingly, the Lower Eocene coal complex is the immediate top-layer of the bauxite. Between teh argillaceous, slaty brown-coal deposit and the bauxite there is a bed of clay the top-stratum of which consists of greyish-black, grey or light grey molluscous clay.Material and MethodThe first sample I investigated had been taken by Dr. B. Molnár from the grey clay situated immediately above the bauxite, in the Kincses" mine. This first sample proves that the clay top-layer is relatively rich in spores and pollen. To be able to carry out the investigations on a broader basis I asked the Board of Directors of the Bauxite Mines of the comitat Fejér to send me samples of the above mentioned complexes from the shafts Kincses" and József" near Iszkaszentgyörgy. In answer to my request I was supplied with several samples of the clay lying immediately above the bauxite, of the coal deposit, and of the molluscous clay on top of them. The investigation of these samples resulted enough data to establish the relation of these strata to the Lower Eocene flora of other territories of Hungary. In this preliminary study the up till now obtained quantitative results are summed up.ResultsThe composite of the spores and pollen in the samples investigated qualitative and quantitative is represented according to the statements of Gőbel (2)
