Abstract:
Rare earth element concentrations in ferromanganese concretions sampled from Slupsk Furrow in the Polish Exclusive Economic Zone are similar to those of concretions from the Gulf of Bothnia. The lack of positive Ce anomalies in the concretions from Slupsk Furrow indicates that they are formed under less oxidizing conditions than spheroidal concretions from the Gulf of Bothnia. Mossbauer studies indicate that poorly crystalline lepidocrosite is the principal iron oxyhydroxide mineral present in these concretions.

Comment:
From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.
