Abstract:
The described sample comes from an outcrop situated in the internal part of the Briançonnais area (Acceglio zone), on the right bank of the high Ubaye valley at 400 m North of the hamlet of Combe Brémond. Two levels of manganese rich and iron rich limestones have been studied and chemically analysed. Rhodonite and pyrosmalite minerals have been identified.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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