Download or read book Volcanic Ash Soils written by S. Shoji and published by Elsevier. This book was released on 1994-01-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

This book was released on 1984-01-01 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists have long speculated on the impact of extreme natural catastrophes on human societies. Archeology and Volcanism in Central America provides dramatic evidence of the effects of several volcanic disasters on a major civilization of the Western Hemisphere, that of the Maya. During the past 2,000 years, four volcanic eruptions have taken place in the Zapotitán Valley of southern El Salvador. One, the devastating eruption of Ilopango around A.D. 300, forced a major migration, pushing the Mayan people north to the Yucatán Peninsula. Although later eruptions did not have long-range implications for cultural change, one of the subsequent eruptions preserved the Cerén site—a Mesoamerican Pompeii where the bodies of the villagers, the palm-thatched roofs of their houses, the pots of food in their pantries, even the corn plants in their fields were preserved with remarkable fidelity. Throughout 1978, a multidisciplinary team of anthropologists, archeologists, geologists, biologists, and others sponsored by the University of Colorado's Protoclassic Project researched and excavated the results of volcanism in the Zapotitan Valley—a key Mesoamerican site that contemporary political strife has since rendered inaccessible. The result is an outstanding contribution to our understanding of the impact of volcanic eruptions on early Mayan civilization. These investigations clearly demonstrate that the Maya inhabited this volcanically hazardous valley in order to reap the short-term benefits that the volcanic ash produced—fertile soil, fine clays, and obsidian deposits.

Book excerpt: Discovered in 1976 by Sheets, and under continuous excavation and study since, the spectacular Ceren site provides us with an unusually clear window into the ancient past with which to view family activities on the frontier of the Mayan civilization. Since volcanic ash did not allow people to selectively remove artifacts, the site is well-preserved and it also largely stopped natural processes of decomposition offering this rare opportunity to study the Mayan past through household archaeology. Known as the New World Pompeii, this study provides a detailed portrait of the life, houses, artifacts, and activity areas of the people who supported the elites with labor, food and goods. As Sheets says, "With any civilization that's being studied, if the households of commoners aren't being investigated, you've eliminated the bulk of the population. How can you understand the society if you ignore most of the people? It's like an ethnography. Only we can't interview people, so their possessions have to speak for them." Art and images from the author's own collection help illuminate the discussions and bring them to life, while the author's discussion of his personal trials and triumphs add a more human dimension to working in the field.
