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 %.

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.
