Abstract (in english)
   The following text enriched our knowledge on the borehole Nosislav-3 which was situated at the Carpathian foredeep about 2 km in front of the line of the flysh nappes. The base of the Karpathian should be subdivided into three developments: 65,0 - 170,0 m pelitic-aleuritic development, 170,0 - 257,0 m psammitic development, 257,0- 340,0 m pelitic development. The assemblages of foraminifers (approximately 300 pieces each) has been evaluated for the following statistical counts. The data has been used for compilation of graphs depicting the diversity, p/b, equitability, dispersity and the values of constance for individual genera. The microfauna of the lower part of the borehole is strongly reduced and it is considered as the 1st zone of the Karpatian by Brzobohatý (1992). Huge number of teleostei bone fragments and strongly pyritized foraminiferal fauna indicates reduction environment of the sedimentation.
   The higher part of the section contains relatively rich assemblages of the Karpathian (foraminifers, clasts of sponge spicules, urchires, molluscs, bryozoans and radiolarians) and it is considered as the 2nd zone of the Karpatian. The represents of genera Uvigerina, Bolivina, Bulimina, Praeglobobulimina dominate, i.e. euryoxibiont elements. The curves show concordant trends in both parts of section (the border at 168,2 m). It corresponds with the change from the psammitic to the pelitic-aleuritic sedimentation. We can conclude, that the reduction of diversity and of development of planctonic foraminifers reflects the sedimentation of more rich psammitic sediments. The onset of the pelitic sedimentation brought improving of conditions for the development of organisms
