Siegl-Farkas, A. and Wagreich, M., 1996. Age and palaeoenvironment of the spherulite-bearing polany marl formation (Upper Cretacceous, Hungary) on basis of palynological and nannoplankton investigation. Acta. Biol. Szeged. 41, pp. 23-36 (1995/1996). Abstract Spherulites and spherulite like forms microlapilli found in formations of different ages may be indicators of geological events in extraterrestrial space and faraway areas of the Earth. The age and conditions of embedding can be deciphered by investigating the enclosing rocks. Shldying the Upper Cretaceous in this way may be of special importance in tracing the latest Cretaceous extinction as well. The borehole Nagygorbo-l can be considered as the "Spherulite-reference section" in the Upper Cretaceous Polany Marl Formation, because the spherulites described by VAsKo-DAvlD (1994) occurred in these biostratigraphically well determined host sediments (SEGL-FARKAS and WAGREICH, 1994).
