(Tables 4-5, page 160) REE contents in ferromanganese concretions from the Gulf of Bothnia and the Barents Sea ...
Ferromanganese concretions from the Svalbard shelf in the Barents Sea show slightly convex shale-normalized REE patterns with no Eu anomalies. Concretions from the Gulf of Bothnia, northern part of the Baltic Sea, exhibit an enrichment of light REE and negative Eu anomalies. This difference is inter...
