Aeolian Dust and Dust Deposits


Book Description

Aeolian Dust and Dust Deposits explores the entrainment, dispersion, and deposition of aeolian dust and dust deposits, with emphasis on transport and deposition of dust derived by deflation of surface sediments and soils. Topics covered range from the mechanisms of fine-particle formation to dust sources, sinks, and rates of deposition. Dust-transporting wind systems are also discussed, along with the grain size, mineralogy, and chemical composition of aeolian dust. Comprised of nine chapters, this book begins with an overview of the general nature and significance of windborne dust as well as the importance of aeolian dust and loess. The next chapter deals with the mechanisms underlying the formation of fine particles, including glacial grinding, frost and salt weathering, and fluvial comminution. The reader is then introduced to dust entrainment, transport, and deposition, together with dust sources, sinks, and rates of deposition. Subsequent chapters focus on the implications of dust deflation, transport, and deposition; dust deposition in the oceans; and loess distribution and the thickness and morphology of loess deposits. This monograph is written primarily for research workers and advanced students in sedimentology, geomorphology, and Quaternary studies, but is also likely to be of value to soil scientists, meteorologists, planetary geologists, engineers, and others concerned with environmental management.

Geographers


Book Description

An annual collection of studies of individuals who have made major contributions to the development of geography and geographical thought. Subjects are drawn from all periods and from all parts of the world, and include famous names as well as those less well known: explorers, independent thinkers and scholars. Each paper describes the geographer's education, life and work and discusses their influence and spread of academic ideas. Each study includes a select bibliography and brief chronology. The work includes a general index and a cumulative index of geographers listed in volumes published to date.




A Historical Geography of China


Book Description

The Chinese earth is pervasively humanized through long occupation. Signs of man's presence vary from the obvious to the extremely subtle. The building of roads, bridges, dams, and factories, and the consolidation of farm holdings alter the Chinese landscape and these alterations seem all the more conspicuous because they introduce features that are not distinctively Chinese. In contrast, traditional forms and architectural relics escape our attention because they are so identified with the Chinese scene that they appear to be almost outgrowths of nature. Describing the natural order of human beings in the context of the Chinese earth and civilization, "A Historical Geography of China" narrates the evolution of the Chinese landscape from prehistoric times to the present.Tuan views landscape as a visible expression of man's efforts to gain a living and achieve a measure of stability in the constant flux of nature. The book ranges the period of time from Peking man to the epoch of Mao Tse-tung. It moves through the ancient and modern dynasties, the warlords and conquests, earthquakes, devastating floods, climatic reversals, and staggering civil wars to the impact of Western civilization and industrialization. The emphasis throughout is on the effect of a changing environment on succeeding cultures.This classic study attempts to analyze and describe traditional Chinese settlement patterns and architecture. The result is a clear and succinct examination of the development of the Chinese landscape over thousands of years. It describes the ways the Communist regime worked to alter the face of the nation. This work will quickly prove to be crucial reading for all who are interested in this pivotal nation. It goes far beyond the usual political spectrum, into the physical and social roots of Chinese history.




A Geography of China


Book Description

This book is intended primarily for serious students of geography but it will also appeal to the general reader. For this reason technical terms have been used as sparingly as is consistent with correct meaning. Wherever the subject matter permits, the author emphasizes geographical growth and shows the interaction of geographical environment and the human activity and institutions. When originally published in the 1960s China was beginning to change with breathtaking rapidity. These changes are presented here against geographical and historical background. Knowledge of the environmental facts is essential to an appreciation of the political, economic, and social problems that have faced the Chinese people.
