The various questions regarding the old problem of the genesis of lake and bog ores have, so far, never been the object of a summarizing paper from a present-day research aspect. Moreover, several special questions still remain quite unclear. The present paper therefore intends to closely examine a number of special questions and to provide a summarizing presentation of the whole problem. However, it is obvious that, in several respects, this paper cannot provide a final answer to all these special questions which belong to the most diverse fields of the natural sciences. Nevertheless, it will clearly delineate the problem for future research.

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.
