Annotated record of the detailed examination of Mn deposits from the Capricorn Seamount, Southwest Pacific Ocean

DOI

Sediments dredged from the flat top of Capricorn Seamount on the eastern edge of the Tonga Trench show it to be of probable Miocene Age. Tonga Trench is judged to be early or pre-Miocene in age. Submergence, ascribed to accommodation of the crustal layer under the superposed load, has been followed by two episodes of erosion, probably in the Pleistocene, In these features and in its depth and age it exhibits a rough agreement with North Pacific seamounts.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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