Description
Abstract
Lower Campanian marls and marly opokas with cherts (»Bibice« borehole, Kraków vicinity) are rich in benthic forams (mainly Stensioeina and Gavelinella species) and rare planktic ones (Hedbergella). The overlying Miocene deposits (Kłodnik and Skawina beds), are developed as conglomerates (equivalent of fresh-water marls in Krakow region) which are completely devoid of microfossils, but younger clays are full of the Badenian forams.
