SUMMARY
The paper presents results of microfaunistic stu-dies on Miocene deposits from drillings Pikule 2 and Pikule 3 situated in the area between Bilgoraj and Rozwad6w (south-west Poland). Miocene Lithotbam-nium limestones yield microfauna related rather to facies than to age of the deposits. Because of lack of any microfaunistic elements indicative of the Lo-wer Badenian, the deposits are tentatively assigned to the Upper Badenian: The Llthothamnium limesto-nes are overlayed by Upper Badenian Pecten beds, typical in development and yielding microfauna
indi-cative of the zones with Neobultmina longa. Ve n g 1.
and Hanzawaia CTa8siseptata (l, u c z k.). Sarmatian deposits overlying the Pecten beds are assigned to two foraminifer zones, the zones with QuinqueZocuUna
sa,.ma.tica K a r r. and ElphUlium hcuerinum (d'O r b.), respeCtively. The description of microfaunas occurring in these deposits is supplemented by an attempt to reconstruct ecological environment of the Miocene
sedimentary basin.
