Book A Study of a Climosequence of Soils Derived from Volcanic Rock Parent Material in Santa Catarina and Rio Grande Do Sul States Brazil

Download or read book A Study of a Climosequence of Soils Derived from Volcanic Rock Parent Material in Santa Catarina and Rio Grande Do Sul States Brazil written by F. Palmieri and published by . This book was released on 1986 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten soils formed from basic volcanic rocks were studied on a 450 km climosequence transect in Santa Catarina and Rio Grande do Sul States, Brazil, to learn how soil properties vary with climate and to provide a data for the developing Brazilian soil classification system. From east to west the altitude drops from 1250 m to 270m, the annual temperature increases from 14.1 C to 19.3 C, and the annual precipitation decreases from 2460 mm to 1850mm. The soils were in the Cambisol, Terra Bruna Estruturada (a new class), Brown Latosol, Terra Roxa Estruturada, and Dusky Red Latosol soil classes of the Brazilian soil classification and in the dystrochrept, Haplumbrept, Paleludult, Haplohumox and Haplorthox great groups of the U.S. Soil Taxonomy. As soil sites get warmer and drier, kaolinite and hamatite contents increase, halloysites and goethite contents decrease, the crystal size of kaolin minerals (kaolinite and 0.7 nm halloysite) increases, soil color changes from brown to dusky red, soil structure changes from well developed blocky to ultra fine granular (massivelike), and surface area and soil swelling decrease. The soil materials mainly had isotic plasmic fabric (isotropic) and had few or no argillans visible in thin section. Gibbsite and halloysite form immediately adjacent to each other in the weathered basaltic rocks. Maghemite occurred in 2.5 YR and redder soils. Upward in the solum organic carbon land goethite contents increase, hematite decreases, the soil color becomes yellower and crystal size of .......

Download or read book The Iron Oxides written by Rochelle M. Cornell and published by John Wiley & Sons. This book was released on 2006-12-13 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together in one, compact volume all aspects of the available information about the iron oxides. It presents a coherent, up to date account of the properties, reactions and mechanisms of formation of these compounds. In addition, there are chapters dealing with iron oxides in rocks and soils, as biominerals and as corrosion products together with methods of synthesis and the numerous application of these compounds. Their role in the environment is also discussed. The authors are experts in the field of iron oxides and have worked on all the topics covered. Much recent data from the authors' own laboratories is included and opportunities for further research are indicated. Special features are the electron micrographs and colour plates together with the many different spectra used to illustrate properties and aspects of behaviour. Numerous tables and graphs enable trends and relationships to be seen at a glance. The book concludes with an extensive bibliography. This book should prove invaluable to industry and to all researchers who, whatever their background and level of experience, are interested in this rapidly expanding field. It is an essential volume for any scientific library and is now in its second, completely revised and extended edition!
