Описание: The significance of manganese ores is very weil known in cast iron and steel production, as weil as in various types of chemical raw material and agricultural fertilizers. The world industry development in recent years requires their increased production in the vicinity of the metallurgical centers in different regions of the world; high grade manganese and associated metalores are needed. Analysis of the world production and consumption of manganese ores by industrial countries indicates convincingly that the highest commercial value belongs to the ores associated with the supergene zone (National Minerals Advi- sory Board, 1981; Coffman and Palencia, 1984; Doncoisne, 1985; Iones, 1990, 1991; Manganese, 1990; McMichael, 1989). The remarkable property of manganese, in contrast to many other types of mineral resources, is that the ore accumulations of this metal are distributed in the wide geochrono- logical interval from the Archean to the present time; these ores are deposited in basins and supergene environments of different types from lakes, internal seas to pelagic and abyssal regions of the World ocean, as weIl as different types of weathering crusts and karst. At the same time the manganese accumulations and features of their mineral and chemical compositions are relatively sensitive indicators, reflecting facies and geodynamic condi- tions of their formation. These properties aid the investigation of the Earth's evolution processes.

Описание: Geochemistry is concerned with the laws governing the distribution of the chemical elements and their isotopes throughout the Earth. With the development of spectrophotometers, radiation counters and nuclear sources over the last 20 years, a flood of analytical data on geological sub- jects has been released, and we ought to make use of it.

Описание: Vernadsky (1934, 1960) who noted both the importance of registration of solid and liquid run-off of rivers, coming into the sea, and "the quality and the character of those elements, which are washed-down into the sea", emphasizing that "wash-down of organic substances into the sea is of great value".

Описание: Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience.
