First published in 1837, Dana's System of Mineralogy has remained the definitive reference on descriptive mineralogy for over 150 years and seven editions. Now, for the first time in half a century, comes a new edition of this undisputed classic—comprehensive, up to date, and More...ready to take mineralogy into the twenty-first century. Dana's New Mineralogy, Eighth Edition describes, catalogs, and classifies the more than 3,000 mineral species currently recognized. Completely rewritten from the seventh edition, the material emphasizes mineral structure and is generously supplemented with unique, specially commissioned structural diagrams. Coverage is carefully balanced, from substantial essays on important species such as calcite and groups such as the feldspars to more compact descriptions of rare minerals. Silicate minerals have been included for the first time, and are classified into homologous groups sharing a similar structure. Entries identify minerals by Dana classification number, name, and chemical formula. Descriptions contain crystallographic data and information on morphology, physical properties, composition, and relationships with other minerals. The Eighth Edition also boasts extensive data on the locations of minerals worldwide, and offers instant access to the primary literature of the past half-century—including often difficult to locate sources from Eastern Europe and China. Extensive indexing makes it easy to find minerals based on proper, variant, regional, or common names. Years in the making, Dana's New Mineralogy, Eighth Edition has been worth the wait. It will continue to be the chosen reference companion of mineralogists, mineral collectors, gemologists, and geologists, as well as chemists, physicists, and amateur enthusiasts of every description. Dana's New Mineralogy classifies and describes the more than 3,000 mineral species currently recognized. Completely rewritten to keep pace with developments in mineralogy today, this Eighth Edition remains unrivaled as the definitive reference on the subject for professionals, students, and interested readers of every background.

Kenya is a thriving country in East Africa: its economy is largely based on the natural environment that frames the tourism sector, mainly through safaris and holidays on the coast. The natural environment also underpins the second largest industry: agriculture. Kenya's social, technological, and industrial developments are a reference for many neighboring countries. Kenya plays a leading role in Africa and attracts huge amounts of investments. Furthermore, the humanitarian community has made Nairobi its base for international headquarters and regional offices. This makes Kenya a possible model for development and investment in its widest sense. This book aims at updating the holistic view on Kenya's natural environment and resources. It provides a sound scientific introduction to this country's physical and socioeconomic setting and its evolution through time and will appeal to a broad audience of students - in Kenya and abroad - as well as those working in the development and humanitarian sectors and to international donors looking for a scientific compendium on Kenya's environment. Its structure and references allow the reader to deepen his or her knowledge of every theme touched on in the book. It combines different aspects of physical geography, water and soil resources and their management strategies. It is written by a blend of international and national experts. It includes specific case studies.

Integrating Scale in Remote Sensing and GIS serves as the most comprehensive documentation of the scientific and methodological advances that have taken place in integrating scale and remote sensing data. This work addresses the invariants of scale, the ability to change scale, measures of the impact of scale, scale as a parameter in process models, and the implementation of multiscale approaches as methods and techniques for integrating multiple kinds of remote sensing data collected at varying spatial, temporal, and radiometric scales. Researchers, instructors, and students alike will benefit from a guide that has been pragmatically divided into four thematic groups: scale issues and multiple scaling; physical scale as applied to natural resources; urban scale; and human health/social scale. Teeming with insights that elucidate the significance of scale as a foundation for geographic analysis, this book is a vital resource to those seriously involved in the field of GIScience.

The book describes the theoretical fundamentals of atmospheric optics as a science of propagation, transformation and generation of electromagnetic radiation in the atmosphere from ultraviolet to microwave radiation. The main characteristics of the planets of the solar system and their atmospheres are given. The equation of the transfer of radiation in different spectral ranges, absorption of radiation by atmospheric gases and aerosol,molecular, aerosol and other types of nonresonant scattering , atmospheric refraction, reflection of radiation from the surface, and glow of the atmosphere are discussed. Methods of calculating radiation for the solar and thermal range of the spectrum are outlined. Problems of radiation energetics and remote probing of the atmosphere are discussed. 1. Solar system: planets and the Sun 2. Earth's atmosphere 3. Propagation of radiation in atmosphere 4. Molecular absorption in atmosphere 5. Scattering of light in atmosphere 6.

Esta obra es un texto clásico y fundamental de gemología. Trata todos los aspectos de esta materia empezando por dar unas nociones de mineralogía en general. Sigue con la gemología descriptiva propiamente dicha; aquí cada gema (ordenadas en orden de dureza decreciente) es tratada exhaustivamente: datos físico-químico-ópticos, datos históricos, génesis, yacimientos (con una amplia descripción de todos los yacimientos del mundo y distintos sistemas de extracción), formas cristalinas, variedades, usos, talla, imitaciones, etc. La obra acaba con la descripción de los métodos de análisis para las piedras preciosas y las perlas y con un elevado número de tablas en donde localizar datos de importancia en la identificación de piedras preciosas.

Infrared and Raman Spectroscopy of Clay Minerals, Volume 8, is an up-to-date overview of spectroscopy techniques used in the study of cationic clay minerals. The methods include infrared spectroscopy, covering mid-IR, near-IR, far-IR and IR emission spectroscopy, as well as FT-Raman spectroscopy and Raman microscopy. This book complements the succinct introductions described in the original Handbook of Clay Science (Volumes 1 and 5B), offering even more depth and featuring the most important literature since the development and application of these techniques in clay science. No other book covers such a wide variety of spectroscopic techniques in a single volume for clay and soil scientists. In addition, some chapters will be of interest to scientists working on planetary geology, e.g. Mars, where some of the equipment either on the surface or orbiting is using spectroscopic methods to determine the soil chemistry/mineralogy of the planet under study
