Abstract:
Todorokite is a very abundant manganese oxide mineral in many deposits in Cuba and has been noted from other localities. Six new analyses are givenl they lead to the approximate formula (Na, Ca, K, Mn+2)(Mn+4, Mn+2, Mg)6O12.3H2O. Electron diffraction data show the mineral to be orthorhombic, or monoclinic with beta near 90°. The x-ray powder pattern is indexed on a cell with a=0.75A, b=2.849A, c=9.59A, beta=90°. A differential thermal analysis curve is given.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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