Описание: This text describes how the repeated glaciation, and subsequent deglaciation, of northern continental Europe during the Quaternary affected Scandinavia and its surrounding areas. The book provides a cross-frontier synthesis and will be invaluable to students and researchers of Quaternary science.

Описание: These proceedings record the results of climate change in many areas which are hyper-arid deserts today but which, almost cyclically, at intervals of thousands or even hundreds of thousands of years, have had a much more humid climate.
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 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.
