    Broschiertes Buch

This volume offers a state-of-the-art review of terrestrial geochemical sedimentology by internationally recognised experts in the field, integrating their most current research with earlier work. For the first time, the full range of these sediments is reviewed in a single volume, from duricrusts (calcrete, laterite and silcrete) to deposits precipitated in various spring, lake, cave and near-coastal environments. Each chapter summarizes the main characteristics of the sediments: morphological, chemical and mineralogical. Distribution, mechanisms of formation or accumulation,…mehr

Produktbeschreibung
This volume offers a state-of-the-art review of terrestrial geochemical sedimentology by internationally recognised experts in the field, integrating their most current research with earlier work. For the first time, the full range of these sediments is reviewed in a single volume, from duricrusts (calcrete, laterite and silcrete) to deposits precipitated in various spring, lake, cave and near-coastal environments. Each chapter summarizes the main characteristics of the sediments: morphological, chemical and mineralogical. Distribution, mechanisms of formation or accumulation, paleo-environmental significance, and relationships to other terrestrial geochemical sediments are also addressed. Geochemical Sediments and Landscapes is unique in its currency and comprehensiveness. An introductory chapter provides an overview of the links between long-term landscape change and geochemical sedimentation. Understanding the origins of terrestrial geochemical sediments can provide insights into past environments, landform preservation and landscape erosion. One chapter is dedicated to the major investigative analytical techniques employed in research, and the final chapter identifies key themes and directions for future research.

Autorenporträt
David J. Nash is Reader in Physical Geography at the University of Brighton. He is widely known for his publications on the links between silcretes, calcretes and landscape evolution in southern Africa, southwest Europe and the UK, as well as his broader research into the geomorphology of dryland regions and Quaternary to recent environmental changes in deserts. Sue J. McLaren is Senior Lecturer in Physical Geography at the University of Leicester. Her research expertise is in terrestrial geochemical sediments (particularly aeolianites and calcretes), reconstructing palaeoenvironments in drylands, and geoarchaeology. Sue has worked extensively in northern and southern Africa, the Middle East, Mexico, and the Caribbean as well as in the Mediterranean and Borneo.
