Halbach Peter 1975 Observation of manganese nodules and encrustations in various lakes of Finland dataset https://doi.org/10.1594/PANGAEA.864229 Halbach Peter 1976 Mineralogical and geochemical investigations on Finnish lake ores journal article Bulletin of the Geological Society of Finland 48(1-2) https://doi.org/10.17741/bgsf/48.1-2.004 33-42 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.

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.
