Authigenic, detrital, and bulk solid phase REY, Al, Ca, Fe, and Mn concentrations from the Mauritanian Margin of METEOR cruise M182

This study reveals how rare earth elements and yttrium (REY) cycle through an ocean margin system, clarifying the mechanisms that govern benthic REY fluxes and the preservation of Nd isotope compositions (εNd) in authigenic sediment phases. This dataset contains rare earth element and yttrium (REY), aluminum (Al), calcium (Ca), iron (Fe), and manganese (Mn) concentrations of bulk, authigenic and detrital sedimentary phases from the Mauritanian margin. Samples were collected during cruise M182 in 2022. Bulk sediment samples were freeze-dried and ground prior to leaching and bulk digestion.
