Book Description
The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas – in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35°N and 35°S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates. The volume discusses the data derived from numerous research and case studies in terms of exploration and dispersion models based on the weathering and geomorphological history. The models permit valid comparisons between equivalent terrains that may be geographically widely separated and situated in quite different climatic environments. The basis of the volume is to view geochemical dispersion within the context of a genetic understanding of the evolution of landforms and the regolith (i.e. landscape geochemistry) and to develop exploration procedures based on this understanding. This book should be of interest to exploration geochemists, economic geologists, soil scientists, geomorphologists and environmental geochemists.

Book Description
Held in 1993 in Niterói, Brazil, the first International Conference on Environmental Geochemistry in Tropical Countries established a starting point for this book. The book opens with a discussion of the points that arose during the closing session, summarised by Dr. E.K. Duursma: The Environment in the Tropics Remains Unknown. Most of the processes that occur in temperate environments turn out to be completely different in the tropics. This can already be seen in Chapter 3, where estimates of radionuclide transfer factors reach values considerably greater than in temperate areas. The utilisation of variables measured in temperate environments for modelling of the tropics can result in completely erroneous conclusions and, worse, inefficient remediation solutions.

Book Description
The Natural Geochemistry of Our Environment shows that the Earth is a water world, whose water is transformed readily from the solid to the liquid to the gaseous state. This book, is an outgrowth of a report prepared in 1979 by Drs. Speidel and Agnew for the U.S. Science, Research, and Technology Subcommittee, provides just such a background to enables one to comprehend the natural system and the way that human activities affect that environment.

Book Description
Accessibly written by a team of international authors, the Encyclopedia of Environmental Change provides a gateway to the complex facts, concepts, techniques, methodology and philosophy of environmental change. This three-volume set illustrates and examines topics within this dynamic and rapidly changing interdisciplinary field. The encyclopedia includes all of the following aspects of environmental change: Diverse evidence of environmental change, including climate change and changes on land and in the oceans Underlying natural and anthropogenic causes and mechanisms Wide-ranging local, regional and global impacts from the polar regions to the tropics Responses of geo-ecosystems and human-environmental systems in the face of past, present and future environmental change Approaches, methodologies and techniques used for reconstructing, dating, monitoring, modelling, projecting and predicting change Social, economic and political dimensions of environmental issues, environmental conservation and management and environmental policy Over 4,000 entries explore the following key themes and more: Conservation Demographic change Environmental management Environmental policy Environmental security Food security Glaciation Green Revolution Human impact on environment Industrialization Landuse change Military impacts on environment Mining and mining impacts Nuclear energy Pollution Renewable resources Solar energy Sustainability Tourism Trade Water resources Water security Wildlife conservation The comprehensive coverage of terminology includes layers of entries ranging from one-line definitions to short essays, making this an invaluable companion for any student of physical geography, environmental geography or environmental sciences.

Book Description
This book examines China’s relations with its weak peripheral states through the theoretical lens of structural power and structural violence. China’s foreign policy concepts toward its weak neighbouring states, such as the ‘One Belt, One Road’ strategy, are premised on the assumption that economic exchange and a commitment to common development are the most effective means of ensuring stability on its borders. This book, however, argues that China’s overreliance on economic exchange as the basis for its bilateral relations contains inherently self-defeating qualities that have contributed and can further contribute to instability and insecurity within China’s periphery. Unequal economic exchange between China and its weak neighbours results in Chinese influence over the state’s domestic institutions, what this book refers to as ‘structural power’. Chinese structural power, in turn, can undermine the state’s development, contribute to social unrest, and exacerbate existing state/society tensions—what this book refers to as ‘structural violence’. For China, such outcomes lead to instability within its peripheral environment and raise its vulnerability to security threats stemming from nationalism, separatism, terrorism, transnational organised crime, and drug trafficking, among others. This book explores the causality between China’s economically-reliant foreign policy and insecurity in its weak peripheral states and considers the implications for China’s security environment and foreign policy. This book will be of much interest to students of Chinese politics, Asian security studies, international political economy and IR in general.

Book Description
Environmental and Low-Temperature Geochemistry presents conceptual and quantitative principles of geochemistry in order to foster understanding of natural processes at and near the earth’s surface, as well as anthropogenic impacts on the natural environment. It provides the reader with the essentials of concentration, speciation and reactivity of elements in soils, waters, sediments and air, drawing attention to both thermodynamic and kinetic controls. Specific features include: • An introductory chapter that reviews basic chemical principles applied to environmental and low-temperature geochemistry • Explanation and analysis of the importance of minerals in the environment • Principles of aqueous geochemistry • Organic compounds in the environment • The role of microbes in processes such as biomineralization, elemental speciation and reduction-oxidation reactions • Thorough coverage of the fundamentals of important geochemical cycles (C, N, P, S) • Atmospheric chemistry • Soil geochemistry • The roles of stable isotopes in environmental analysis • Radioactive and radiogenic isotopes as environmental tracers and environmental contaminants • Principles and examples of instrumental analysis in environmental geochemistry The text concludes with a case study of surface water and groundwater contamination that includes interactions and reactions of naturally-derived inorganic substances and introduced organic compounds (fuels and solvents), and illustrates the importance of interdisciplinary analysis in environmental geochemistry. Readership: Advanced undergraduate and graduate students studying environmental/low T geochemistry as part of an earth science, environmental science or related program.
