Abstract:
Eighty-seven manganese nodules, representing 6 different locations at depths ranging from 2400 to 7400 m, from the eastern edge of the Blake Plateau were studied. Most of the nodules contained secondary structural textures resulting from the apparent burrowing of marine microfauna. This biogenic activity produced modification of the original growth patterns. In many cases the burrowed zones served as favored sites for redeposition of iron-manganese material. Transmitted light and scanning electron microscope analysis revealed the presence of 3 types of organic activity: (1) agglutinated foraminiferal tests; (2) pre-bored clay particles acting as nuclei or later included during nodule growth; and (3) younger burrows that cross-cut all older structures. In many instances this cross-cutting action resulted in almost total eradication of areas of the original growth patterns. The final texture may be mistaken for a similar growth texture previously classified as mottled, but a more specific genetic term might be 'disrupted'.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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