Abstract:
Characteristic black nodules have been retrieved in 1922 from the bed of the Kichijo River, that runs along the Tanakamiyama mountain in the Oni Province and ends into Lake Biwa in Japan. Their radiocativity has been studied along with that of crusts of similar nature found covering rock formations in the vicinity overlooking the stream. The high content in radium observed may be due to the high uranium content of the granite host rock typical of the Tanakamiyama formation.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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