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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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

| Manuels_D | 47.5107 | -52.9187 | 127 | 219A4 | 3 | Buried | Mn nodule | Many | 0.5-2.0 cm | Shale | Lower Cambrian | Rhodochrosite and manganiferous calcite nodular bed and may be considered the base of the manganese zone at Manuels. Thickness is two feet. Lies on a thick green shale formation | The nodules are discoidal in shape and vary in diameter from 0.5 to 2.0 cm. | hdl:10013/epic.46463.d001 |
| Manuels_D | 47.5107 | -52.9187 | 127 | 219A6-7 | 2 | Buried | Mn nodule | Many | 0.5-2.0 cm | Shale | Lower Cambrian | Somewhat fine-grained and gritty red shale, measuring 1.5 foot in thickness. Manganese occurs as primary carbonates and oxides in the form of thin jasper-like bands of green and light chocolate brown color, and as lenticles, and nodules | The structure of the concretions is nodular and concentric and some of the concentric shells are oolitic. In all the thin sections of nodules the most conspicuous feature is the zonal arrangement of crystalline and indeterminable portions. | hdl:10013/epic.46463.d002 |
| Long-Pond_D | 47.4872 | -52.9622 | 166 | 219F2 | 3 | Buried | Mn nodule | Many | 1.0 cm | Shale | Lower Cambrian | Embedded in green shale, phosphatic rich in the upper levels. Nodular shale. 10 feet down the section | Abundant nodules altered for the most part to a wad and clay, some having secondary manganese or white clay centers and clay border zones and others with limonitic green clay centers with secondary manganiferous clay border zones. | |
| Smith-Point_D | 48.1915 | -53.8477 | 97 | 230D27 | 60 | Buried | Mn nodule | Several | 0.5-1.0 cm | Shale | Lower Cambrian | Manganese limestone (manganiferous dolomitic shale), 3.5 feet thick, 180 feet from base. Between two layers of bright red fissile shale somewhat oölitic with abundant trilobites and other organic forms | Irregular nodules with crystalline areas in a matrix of argillaceous matter |
