Abstract

Deep sea manganese nodules from the Southern Ocean have been studied using chemical analysis, X-ray diffraction, optical mineragraphic and electron probe microanalysis techniques. The nodules were lower in manganese, iron and associated elements than the average grade of manganese nodules from other localities. A number of chemical relationships have been observed. Nickel, copper, cobalt, barium, zinc, molybdenum, strontium, sulphur and phosphorus are associated with the manganese rich phases and titanium with the iron rich phases. X-ray diffraction analysis and electron probe microanalysis results indicate that the manganese phases are similar to the disordered δ-MnO2 and “manganite” phases reported by other workers.

Zusammenfassung

Tiefsee-Manganknollen aus dem südlichen Ozean wurden mit Hilfe von chemischen Analysen, Röntgenbeugung, mikroskopischer Untersuchung und Anwendung von Mikroelektronensonden untersucht. Die Knollen enthielten weniger Mangan, Eisen und Begleitelemente als das Durchschnittsquantum in Manganknollen aus anderen Gebieten. Eine Anzahl chemischer Ähnlichkeiten wurde beobachtet. Nickel, Kupfer, Kobalt, Barium, Zink, Molybdän, Strontium, Schwefel und Phosphor treten gemeinsam mit den manganreichen Erscheinungsformen, und Titan zusammen mit den eisenreichen auf. Ergebnisse der Röntgenbeugungsanalyse und Mikroelektronensondenuntersuchung ergaben, daß die Manganphasen Ähnlichkeit haben mit ungeordneten δ-MnO2 und „manganitischen“ Erscheinungsformen, über die andere Wissenschaftler berichtet haben.
