Beschreibung:
Geocryology is the science studying the effects of ground temperatures below 0°C on the surface layers of the crust of the Earth. Areas with perennially frozen ground occupy over 20% of the land areas on Earth. The last book on this subject that dealt with processes and the landforms was published in 1979, and is therefore greatly out of date. The book is divided into three parts, viz., the introduction and characteristics of permafrost, the unique landforms found in these regions, and the limitations and problems affecting development in these areas. This book incorporates considerable Russian and Chinese research and expertise, providing a uniquely comprehensive, global overview.
Introduction and characteristics of permafrost. Definition and description. Cryogenic processes where temperatures dip below 0°C. Factors affecting permafrost distribution. Distribution of permafrost. Permafrost landforms. Frost cracking, ice-wedges, sand, loess and rock tessellons. Massive ice in lowlands. Permafrost mounds. Mass wasting of granular and fine-grained materials in cold climates. Mass wasting of blocky materials in colder climates. Cryogenic patterned ground. Thermokarst and thermal erosion. Use of permafrost areas. The mechanics of frozen soil. Foundations in permafrost regions: Building stability. Roads, Railway and Airfields. Oil and Gas industry. Mining in permafrost areas. Provision of utilities. Agriculture and forestry. References. Index.
