Isotope Geochemistry: The Origin and Formation of Manganese Rocks and Ores is a comprehensive reference on global manganese deposits, including their origins and formations. Manganese is both a significant industrial chemical, critical for steel-making, and a strategic mineral, occurring in abundance only in certain countries. Furthermore, it is used effectively in CO2 sequestration, helping to mitigate greenhouse gas emission challenges around the world. For these reasons, exploration for manganese is very active, yet access to the primary academic literature can be a challenge, especially in field operations.
Isotope Geochemistry brings this material together in a single source, making it the ideal all-in-one reference that presents the supporting data, analytics, and interpretation from known manganese deposits. This book is an essential resource for researchers and scientists in multiple fields, including exploration and economic geologists, mineralogists, geochemists, and environmental scientists alike.

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: 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.
Описание: The degree of sum- mer insolation on the Earth`s northern Hemisphere is believed to be relevant to climate because the North Atlantic is where cold saline water is being formed. In contrast, upwelling deep water transfers nutrients from the deep ocean to the surface water.

Описание:
Building on the success of its 1993 predecessor, this second edition of Geochemistry, Groundwater and Pollution has been thoroughly re-written, updated and extended to provide a complete and authoritative account of modern hydrogeochemistry.
Offering a quantitative approach to the study of groundwater quality and the interaction of water, minerals, gases, pollutants and microbes, this book shows how physical and chemical theory can be applied to explain observed water qualities and variations over space and time. Integral to the presentation, geochemical modelling using PHREEQC code is demonstrated, with step-by-step instructions for calculating and simulating field and laboratory data. Numerous figures and tables illustrate the theory, while worked examples including calculations and theoretical explanations assist the reader in gaining a deeper understanding of the concepts involved.
A crucial read for students of hydrogeology, geochemistry and civil engineering, professionals in the water sciences will also find inspiration in the practical examples and modeling templates.
