Abstract:

9 manganese crusts retrieved from the Manihiki Plateau area by R/V Tui have been analysed by instrumental neutron activation analysis in order to characterize their geochemical nature. Most of the Mn crusts are of hydrogenous origin. Delta-MnO2 is the principal Mn mineral in the crusts.

Keyword(s):

Geochemistry; manganese micronodule; manganese nodule; ocean; sediment

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
