Abstract:
One of geological peculiarities in the Julian Alps is red pelagic limestone containing manganese nodules. They are encountered at several localities in the Bovec, Trenta and Krn area, occurring in some metres thick horizon of the Upper Liassic age. The nodule forms are disc-like attaining up to 12 cm in diameter. Mineral composition is characterized by pyrolusite, psilomelane, manganite and hausmannite. The shear of Mn in the nodules is low ranging from 0.8 % to 3.5 %. The Fe amount attains up to 1,7 %, in some samples, however, Fe exceeds Mn. At Mangart and at Begunjscica, Mn ore beds occur in a thinner horizon in a sequence of slate, radiolarite and crinoidal limestone. Herein, the amount of MnO reaches up to 60 %.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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