Abstract:
Erben and Fieberling Guyots lie about 800 and 600 miles, respectively, west of San Diego, California. Their tops are largely rocky. The sparse deposits consist of a thin patchy veneer of calcareous and siliceous organic remains and small amounts of clastic mineral grains and basalt fragments derived from the underlying rocks. The rocks of Erben Guyot are encrusted with manganese dioxide. Geomorphic and petrologic evidence indicate the seamounts to be extinct basaltic volcanoes. The drowned summit platforms of Erben Guyot (400 fathoms) and Fieberling Guyot (280 fathoms) are considered to be planes of marine abrasion cut by wave action within a few fathoms of sea level. Possible explanations are discussed for the present deeply drowned position of these truncated surfaces. It is concluded that these extinct submarine volcanoes constitute an uncompensated load on the earth's crust of such magnitude that they tend to subside slowly because of yielding of the earth's crust. Foraminifera of Miocene age have been identified in the calcareous cement of a breccia from the Erben Guyot surface. Thus, this guyot appears to have been truncated in Miocene or earlier time.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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