Rare earth elements as indicators of formation conditions of Cretaceous phosphorites: Evidence from the East European Platform

Cretaceous phosphorites are abundant in the sedimentary cover of the central East European Platform as grains, pebbles, nodules, and economic-grade beds. We studied Cenomanian phosphorite deposits of the Voronezh ante-clise (Polpinsk, Shchigrovsk, Svobodinsk deposits and several occurrences), the Ca...

Zusammenfassung:	Cretaceous phosphorites are abundant in the sedimentary cover of the central East European Platform as grains, pebbles, nodules, and economic-grade beds. We studied Cenomanian phosphorite deposits of the Voronezh ante-clise (Polpinsk, Shchigrovsk, Svobodinsk deposits and several occurrences), the Campanian Unecha deposit, and the Valanginian VyatkaKama deposit in the Vyatka Kama anteclise.
