Abstract:

During the "Challenger" Deep-Sea Exploring Expedition a great many peculiar-looking manganese nodules or concretions were dredged from the floor of the ocean at great depths, chiefly in the Red Clay areas of the Pacific. In the present paper we propose to point out the distribution of the oxides of manganese in the geological series of rocks, in fresh and sea water, and in marine deposits, with special reference to our explorations in the lochs of the west of Scotland; to give an account of investigations undertaken to ascertain the source of the manganese present in marine deposits in the form of the higher oxides, and thereafter to discuss the various views that have been advanced to explain the formation and distribution of manganese concretions in marine deposits in general.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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