Abstract:
Manganese nodules and manganese crusts covering basalt or volcanic breccia rocks have been analysed using various methods. Energy dispersive X-Ray analysis (EDAX)was used for the determination of Fe, Mn, Ti, Mg, Al, Si, K, Ca, S. Measurements have been performed on pellets built from the samples reduced to powder. Results are presented as average of about 10 point measurements. Concentrations have been normalized at 100% of total metal oxides. Atomic absorption analysis was performed on the same samples for Ni, Cu, Co and Zn elements.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
This dataset represents the digitized Table Annex7-B, pages 205-207 of the related publication.
