Acta Biologica Szeged 13, (3—4), pp. 11—13 (1967) THE RECYCLED SPOROMORPHS OF THE BORING NO. NY-1 IN KECSKEMÉT M. KEDVES—MARTA KARÁCSONYI Institute for Plant Morphology and Systematic of the Attila József University, Szeged (Received July 21, 1967.) Introduction The boring under examination was surrounded at its deepest site by Sarmatian and Tortonian layers proved by the fauna, and it has come to a stop in a depth of 2127 m in Tortonian layers. According to B . M o l -n á r's oral information, geologists suppose on petrological basis a recyling of an age older than the Tertiary period, and consider the whole material to be possibly reworked. As referred to by W i l s o n (1964) and as expressed in a former publication by us (K e d v e s , E n d r é d i and S z e l e y 1966), in the Hungarian relations, the palynological method is highly suitable to illuminate the conditions of reworking, therefore we have considered useful to investigate the layers in question. Obtaining the material for our research work from Dr. M á-r i a M i h á l t z - F a r a g ó , we wish to express her our thanks for her so kind help in this way, as well. Material and Method On the basis of geological period determination, we have investigated one sample from the Sarmatian layers (1931.0—1933.0 m), and four ones from the torton layers (1968,0—1970,0; 1005,5—2004,5; 2096,0—2098,0; 2121,0—2125 0 m) Results The samples examined are generally rich in sporomorphs, reffering to the middle Tertiary period. The number of the sporomorphs recycled is small. As the assemblage of the reworked forms is by and large the same in every sample, the demonstrated secondary sporomorphs can be summarized as follows: 12 Zonalasporites fsp . i Zonalasporites fsp.i Ovalipollis cf. varus K l a u s 1960 Pityosporites cf. illustris L e s c h i k 1955 Pityosporites devolvens L e s c h i k 1955 Lunatisporites acutus L e s c h ik 1955 Vitreisporites fsp. Parcisporites fsp. Platysaccus fsp. Scopulisporites fsp.i Scopulisporites fsp.j Tricolpites (Eucommiidites) troedssonii E r d t m a n 1947. Two Hystrichosphaeridae types (A, B) are referring to saltwater origin, and also a Peridinium sp. of a probable sea ecology has been observed. Discussion About Hungary there are but comparatively few paleo- and mezo-zoic palynological publications. Therefore, the age of being reworked can be indicated only approximately on the basis of the sporomorphs recycled, being anyway very few in number. The observed secondary assemblage is separated well from the assemblages arising from the period between the upper Permian and the upper part of middle Triassic published from boring No. 1. Mesteri ( J u h á s z , K ő v á r y, K r i v á n - H u t t e r and M a j z o n 1964) and the upper part of the middle Trias period, as well from the Permian-Triassic assemblage in Solymár ( K e d v e s 1965 c). It is difficult, as well to identify it with the younger assemblage of the Triassic period, first of all with the spore-pollen assemblage described by V e n k a t a c h a l a and G ó c z á n (1964) from the Bakony mountain. In connection with this, the complete lack of the families of the Operculati group (Classopollis, Circulina, Granuloperculatipollis) is conspicuous. It is interesting that the most types are similar to the assemblage from the Keuper period published by K r á u s e l and L e s c h i k (1955). On the otherhand, it is separated well from the sporomorph assemblage from the Liassic period known from the publications of G ó c z á n (1956) and B o n a (1963). On the basis of a comparison with the forms of K r á u s e l and L e s c h i k (1955), the age of recycling can be fixed in the Trias, more close in the upper part of Trias. It differs from the sporomorph assemblage recycled and formerly published from the area of the Great Hungarian Plain ( K e d v e s , E n d r é d i and S z e l e y 1966) first of all by the fact that, in the present case, the recycling is simple while in the borings at Macs, Kemecse, Szentes and Makó a complex recycling could be ascertained. The lack of spores, unaccustomed opposite to the observations so far, is very interesting and obvious. From this fact the conclusion can be drawn that the transferred sediment was far from 13 the zone of the littoral vegetation. A comparison with the transferred forms, discussed in the former paper, from the Triassic period is rather difficult because of the poverty of the assemblage, it is similar anyhow, in some degree, for the most part to the type known from the surroundings of Macs and Kemecse. Summary The recycled spore pollen assemblage of five samples from the lower site of the boring No.Ny.-l in Kecskemét has been investigated. On the basis of our results, it can be ascertained as follows: 1. The recycling is simple, only sporomorphs from the Triassic period could be observed among the sedimental autochtonous sporo-morphs. 2. From the lack of spores in the secondary sporomorphs the conclusion can be drawn that the zone of the transferred sediment was far from the coastal line. References B ó n a . J.
