https://www.pangaea.de/ information publisher tableDigital Supplement to: Halbach, Peter (1976): Mineralogical and geochemical investigations on Finnish lake ores. Bulletin of the Geological Society of Finland, 48(1-2), 33-42, https://doi.org/10.17741/bgsf/48.1-2.004 The limnic ferromanganese ore concretions in some Finnish lakes are described. Their chemical and mineral compositions have been measured as have their natural surroundings — the latter by means of physico-chemical in-situ analysis. The sources of the nodules' contents are discussed, and a theory based on the calculated precipitation fields of the important ore minerals is presented for the ore formation. completed Halbach, Peter principalInvestigator NOAA-MMS NOAA and MMS Marine Minerals Geochemical Database theme 1995-01-01 creation PANGAEA

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.
