Book Description
Manganese mineralization is diverse in occurence, origin, mineralogy and geochemistry. This volume includes a review of the range of terrestrial Mn deposits and their relative abundance through geological time. Experimental and modelling approaches to Mn geochemistry and mineralogy can further aid our understanding of the formational and depositational processes involved and thereby our interpretation of deposit metallogenesis.
Marine Minerals in Exclusive Economic Zones

Book Description
In the last ten years offshore mineral exploration programmes have increasingly concentrated on the 200 mile Exclusive Economic Zones adjacent to coastal states. This book gives an integrated treatment of the various mineral types occuring in these zones, their genesis, distribution and economic importance. The book opens with a broad overview of the subject and discusses the legislative issues relevant to marine and mineral exploitation. Chapters then deal in turn with aggregates, placers, precious coral, phosphorites, manganese nodules, cobalt-rich manganese crusts and hydrothermal deposits. An international set of case studies illustrates each type of deposit, many studies based on the author's own experience in marine mineral evaluation programmes around the world during the past 25 years.

Book Description
Manganese nodules were first discovered on the ocean floor 160 miles south-west of the Canary Islands on February 18, 1803, during the first complex oceano logical cruise of the Challenger. They surprised researchers by their unusual shape and also by their unusual chemical composition; nevertheless for many years after wards, they were considered merely as one of Nature's exotic marine tricks. After the Secpnd World War, a comprehensive investigation of the World Ocean started, and new data were obtained on a wide distribution of manganese nodules and their polymetallic composition, that made scientists consider nodules as one of the major characteristics of the deep oceanic zone. Recently, meaning since the 1960's, nodules have been recognized as a potential ore source, investigation of which is stimulated by the progressive depletion of land-based mineral resources. Several generations of scientists from various countries have contributed to the problem of exploration of manganese nodules on the ocean floor. Though the problem has been posed, it has not been solved yet because it required, in its turn, a scrutiny of some fundamental aspects such as composition, nature, accretion r'ate of nodules and retrieval of nodule fields. These problems have been discussed in thousands of papers and larger publications; see, in particulare, Mero, 1965; Horn, 1972; Morgenstein, 1973; Bezrukov, 1976; Glasby, 1977; Bischoff and Piper, 1979; Lalou, 1979; Manganese nodules, 1979; Varentsov, 1980; Cronan, 1980; Manganese nodules . . . , 1984, 1986.
