The author has studied sediment-soil sections in Iran in great detail in order to reconstruct and depict Middle to Upper Quaternary climate change and landscape evolution in this region. Following a comprehensive review of loess occurrences in Iran and adjacent countries, in fact, Western Asia, the study concentrates in detail on the soil sedimentology and pedology of loess reference sections of the Caspian lowlands (Northern Iran) and on loess-like sediments of the Persepolis Basin (Southern Iran). Both sections are characterized by sub-humid to semi-arid climates and present ideal laboratories for studying past climate changes and their effects on sediment deposition and soil formation. The sedimentological/paleopedological analyses presented here include detailed profile descriptions and copious micromorphological, geochemical and mineralogical data. Based on pedostratigraphic correlations and systematic luminescence- and radiocarbon dating, a new chronostratigrapic framework of sediment deposition and soil formation in Iran is described. The framework developed herein is subsequently used to correlate the studied sections with sediment-soil sequences of West and Central Asia and Eastern Europe. The synthesis chapter describes how paleoclimatic conditions affect loess accumulation, soil formation and geomorphodynamics during the formation of sediment-soil sequences, considering the importance of human impact on the geomorphodynamic settings. The book is of interest to pedologists, paleopedologists all researchers interested in loess, soils, climatic controls of their formation in the Quaternary.

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.

An in-depth analysis of the aeolian Quaternary record and current methods used in its study. With an emphasis on stratigraphical records gathered in the loess-palaeosol sequences of China and central Asia, the papers examine data derived from a range of complementary techniques: the marine oxygen isotope record, magnetostratigraphy, spectral analysis, magnetic susceptibility, anisotropy of magnetic susceptibility, rock magnetism, magnetic grain size, magnetic separation using the citrate-bicarbonate-dithionite technique, particle size analysis, palaeosol micromorphology, canning electron microscopy, carbon isotopes, electron microscopy, carbon isotopes, electron spin, resonance and luminescence dating.

The Quaternary has been a period of major climatic and environmental oscillations, and our knowledge of these past variations is important for our understanding of the possible impact of human activity on the present-day environment. First published in 1999, Quaternary Climates, Environments and Magnetism presents an account of the rich variety of uses of magnetic measurements in the environmental geosciences. Ten chapters by leading world authorities describe the highlights of environmental magnetic work during the last decade and identify directions for future research. Emphasis is placed on a multidisciplinary approach to achieve a more thorough understanding of the environmental processes involved. This volume will be of interest to research scientists from a wide range of disciplines working on Quaternary environments, including earth and environmental sciences, physical geology, geography and palaeoclimatology. It will also be valuable as a supplementary text for graduates and advanced undergraduates.

During the Quaternary period, the geological epoch covering the last 1.8 million years, major climatic fluctuations and widespread glaciation had a marked impact on soil characteristics and distribution patterns in the northern hemisphere. This handbook summarizes the evidence for climatic change derived from deposits of land areas and from deep ocean sediments. The author considers soil patterns in eastern England, the midwestern United States, the Netherlands, Belgium, and northern France, examines the main Quaternary processes influencing soil patterns, and outlines their effects at various scales.
