The geochemical behavior of REE has been tested in the Umbro-Marchean (Italy) pelagic sequences of Cretaceous-Paleocene age. REE were determined by 1NAA in a number of limestone, marl and clay samples. Both chondrite and shale normalized patterns are discussed: .the observed REE amounts and distributions are mainly attributed to highly complex diagenetic processes

Abstract
The geochemical behavior of REE has been tested in the Umbro-Marchean (Italy) pelagic sequences of Cretaceous-Paleocene age. REE were determined by 1NAA in a number of limestone, marl and clay samples. Both chondrite and shale normalized patterns are discussed: .the observed REE amounts and distributions are mainly attributed to highly complex diagenetic processesFile in questo prodotto:
