Upper Cretaceous variegated marls of a Węglówka-type facies are exposed in the form of olistoliths within the Zuber-type salt deposits at the higher exploitation level of the "Kunegunda" Drift in the Wieliczka Salt Mine. This is the southernmost zone of occurrence of redeposited blocks of the Carpathian flysch sediments within the Miocene salt deposits of the Carpathian Foredeep. The variegated marls contain considerably diversified assemblages consisting only of small benthic foraminifera, including both agglutinated and calcareous taxa. Basing on the ranges of the characteristic species the variegated marls in the "Kunegunda" drift are dated as Turonian-Campanian. Two zones of benthonic agglutinated foraminifera have been recognised: the Uvigerinammina jankoi and Goesella rugosa zones. The foraminiferal assemblage of the youngest segment of the Węglówka marls is dominated by calcareous benthonic taxa with Stensioeina gracilis Brotzen as the most numerous species. Its presence indicates a Campanian age of this part of the studied deposits.
