Book excerpt: n weathering would result in soils of low or high availability of base cations. The presence or absence of ecological zones (large areas of similar environmental conditions consisting of temperature, moisture, and fertility, which are manifested by characteristic vegetative communities) were modeled as multivariate logistic functions of climatic, topographic, and geologic variables. Accuracy of ecozone models ranged from 69- to 95-percent correct classification of sample plots; accuracy of most models was > 80 percent. The most important model variables were elevation, precipitation amount, and lithologic group. A regional map of ecological zones was developed by using a geographic information system to apply the models to a 30-m digital elevation dataset. Overall map accuracy was refined by adjusting the best probability cut levels of the logistic models based on expert knowledge and familiarity of the authors with known ecological zone boundaries throughout the study area.

Download or read book Global Heritage Stone written by J.T. Hannibal and published by Geological Society of London. This book was released on 2020-11-18 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heritage stones are building and ornamental stones that have special significance in human culture. The papers in this volume discuss a wide variety of such materials, including stones from Europe, Asia, North and South America, Africa and Australia. Igneous (basalt, porphyry, granite), sedimentary (sandstone, limestone) and metamorphic (marble, quartzite, gneiss, soapstone, slate) stones are featured. These have been utilized over long periods of time for a wide range of uses contributing to the historic fabric of the built environment. Many of these stones are of international significance, and so are potential Global Heritage Stone Resources, that is stones that have the requisite qualities for international recognition by the Heritage Stones Subcommission of the International Union of Geological Sciences. The papers bring together diverse information on these stones ranging from their geological setting and quarry locations to mechanical properties, current availability, and uses over time. As such the papers can serve as an entry into the literature on these important stones.

Download or read book Chemical Elements in the Environment written by Clemens Reimann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: How large is the natural variation in concentration of the various elements in different media? How do the oft-cited "World average concentrations" in different media compare with actual analytical data? How low a detection limit do I need to attain if I want to analyse for an element in soils, sediments, water or plants? All these questions and many more can be answered by using this unique reference book. It collates data on the most important properties and uses of all naturally occurring chemical elements. It combines these with data obtained from actual analyses of different sample media (soil, stream sediment, stream water, ground water, plants, human body fluids). This combination of facts and actual data makes this book suitable for learning and teaching applied geochemistry as well.

Available in PDF, EPUB and Kindle. Book excerpt: Short articles summarize environmental geochemical studies of metallic mineral deposits in Alaska, including massive sulfide, gold, mercury, chromium, and uranium mines and deposits. The studies report metal and acid concentrations in samples collected around such mines and deposits, and evaluate environmental effects of the deposits. The articles are written in a style intended to reach a general audience.

Download or read book Science and Global Challenges of the 21st Century Science and Technology written by Alvaro Rocha and published by Springer. This book was released on 2021-10-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises the proceedings of the International Perm Forum “Science and Global Challenges of the 21st Century” held on October 18th – 23rd, 2021, at Perm State University, Perm, Russia. Global challenges, which determine the main trends in the development of social and economic life in the XXI century, require the integration of specialists in various fields of knowledge. That is why the main principle of this edition is interdisciplinarity, the formation of end-to-end innovation chains, including fundamental and applied research, and the wide application of smart innovations, networks, and information technologies. The authors seek to find synergy between technologies and such fields as computer science, geosciences, biology, linguistics, social studies, historical studies, and economics. The book is of interest to researchers seeking nontrivial solutions at the interface of sciences, digital humanities, computational linguistics, cognitive studies, machine learning, and others.
