K.C. Misra, "Understanding Mineral Deposits"

K.C. Misra, "Understanding Mineral Deposits"
Springer | 1999 | ISBN: 0045530092 | 864 pages | PDF | 50,1 MB

The challenge of finding new orebodies to satisfy the ever increasing demands for mineral commodities has to be met, in addition to improved techniques of exploration, mining, extraction, and management, by a better understanding of the geologic setting and genesis of the various classes of mineral deposits. A substantial part of the book is devoted to a discussion, with appropriate examples, of principles that govern the formation of mineral deposits and the various kinds of field and laboratory data that can be used to interpret their genesis. The rest of the book discusses the characteristics of selected classes of deposits, their relationship with the crustal evolution in space and time, and on the application of available data to the formulation of viable genetic models that provide the basis for exploration strategies. Audience: The book is intended as a text for an introductory course in economic geology at senior undergraduate and graduate levels, but it should also serve as a useful information resource for professional economic geologists.

Handbook of Paleoanthropology: Volumes 1-3: T. Hardt (Author), Winfried Henke (Editor), Ian Tattersall (Editor)

Paleoanthropology is perhaps the most multidisciplinary of all the sciences. Any complete account of the evolution and cultural and biological context of Homo sapiens must combine information from geology, paleoecology, primatology, evolutionary biology and a host of other fields. Above all, historical information needs to be combined with, and interpreted in the light of, what we know of the living world. Paleoanthropology is also an actively developing field in which much remains to be settled. The three volumes of this handbook bring together contributions by the world's leading specialists that reflect the broad spectrum of modern paleoanthropology, thus presenting an indispensable resource for both professionals and students alike. Volume 1 deals with principles, methods, and approaches. In recent years, enormous advances have been made in such areas as phylogenetic analysis, paleoecology and evolutionary theory and philosophy. The contributions in this first volume present the state of the art in these fields, provide succinct introductions to them and reflect the many ways in which they interact. As human beings are primates, Volume 2 is devoted to primate origins, evolution, behaviour, and adaptive variety. Its emphasis is on integration of fossil data with the vast amount that is now known of the behaviour and ecology of living primates in natural environments. Volume 3 deals with the fossil and molecular evidence for the evolution of Homo sapiens and its fossil relatives (the family Hominidae or subfamily Homininae, according to taste, a matter that we have left to the individual contributors).

"Oceans – Biomes of the Earth"

Trevor Day "Oceans – Biomes of the Earth"
Published by Chelsea House Publications | Publication date : April 2006 | ISBN : 0816053278 | PDF | 273 pages | English | 16.2 MB

The oceans are teeming with life of all kinds. Changing sea levels, plate tectonics, chemical cycling, sedimentation, and the atmosphere greatly impact these habitats. The ocean's currents and sea level are tied closely to weather patterns and in turn to such issues as global warming and El Nino.
"Oceans" provides a complete overview of the ecosystem that exists in these bodies of water. From the coastal wetlands to the deep ocean waters, the geography, geology, chemistry, and physics of oceans are thoroughly examined in this volume.
Today, the impact that human use of ocean resources has on these habitats, including habitat loss and overharvesting, is in constant debate. "Oceans" looks at these possible threats and concludes with a balanced look at the ways to manage the oceans, as well as the future of this ecosystem.

"Taiga – Biomes of the Earth"

Trevor Day "Taiga – Biomes of the Earth"
Published by Chelsea House Publications | Publication date : April 2006 | ISBN : 0816053294 | PDF | 241 pages | English | 15.4 MB
Taiga is a biome of the Northern Hemisphere, between tundra to the north and broad-leaved forest and temperate grassland to the south. Taiga includes dense forest, open forest, and jigsaw puzzles of forests, wetlands, and lakes that can be found in northwestern and northeastern America, northern Europe, Siberia, and East Asia. Examining its geography, geology, climate, and biodiversity, "Taiga" describes this unique ecosystem in a clear, complete manner. Human uses of taiga date back thousands of years to Eurasian hunters and fishers crossing the Bering land bridge into present-day North America. Today, hunting, logging, and mining are a few of the ways this habitat is used. Threats resulting from this development include overharvesting from hunting and logging, clear-felling, and the spread of agriculture. This volume also examines ways of managing taiga, including the movement to conserve taiga habitats through the creation of reservations and sanctuaries.

"Geological and Soil Evidence. Forensic Applications"

"Geological and Soil Evidence. Forensic Applications" by Kenneth Pye
CRC | 2007 | ISBN: 0849331463 | 362 pages | PDF | 9 Mb

This book provides an authoritative introduction to the nature and properties of geological and soil materials that may be used as trace evidence and the techniques used to analyze and evaluate them. It emphasizes the use of geoscience in forensic analyses, including geophysical, meteorological, and geomorphological data.

This inclusive book covers material types and analytical strategies used in examining both the common components of geological evidence, such as rocks, dusts, minerals, spores, and microfossils, as well as anthropogenic particles like pottery and brick.
It instructs on particle characterization based on physical, chemical, and mineralogical traits such as color, shape, density, and elemental and isotopic composition. It also explains sampling and handling procedures particular to criminalistics and introduces analysis, evaluation, and decision-making practices based on statistical significance and the weighing of different types of evidence.


Plate Tectonics (Science Foundations) By Stephen M. Tomecek

Plate Tectonics (Science Foundations) By Stephen M. Tomecek
Publisher: Chelsea House Publications 2009-05-30 | 102 Pages | ISBN: 1604130148 | PDF | 10 MB

The development of the plate tectonic theory was one of the great revolutions in the history of science. Before the plate tectonic theory, most scientists believed that Earth was a static planet that never really changed. Working like detectives, a small group of pioneering individuals slowly pieced together an entirely different picture of our Earth, showing that the planet is really a dynamic, active world. Over the course of millions of years, continents collided with each other, oceans opened and closed, and mountains rose and fell - and these changes continue today. "Plate Tectonics" examines the evolution of plate tectonic theory from its beginnings as a wild idea of drifting continents to its acceptance as the main concept that drives geology today. The book also focuses on the lives and achievements of those individuals who fought great odds to give rise to one of the most important theories in science.

Quartz, zeolites, gemstones, perovskite type oxides, ferrite, carbon allotropes, complex coordinated compounds and many more?all products now being produced using hydrothermal technology. Handbook of Hydrothermal Technology brings together the latest techniques in this rapidly advancing field in one exceptionally useful, long-needed volume. The handbook provides a single source for understanding how aqueous solvents or mineralizers work under temperature and pressure to dissolve and recrystallize normally insoluble materials, and decompose or recycle any waste material. The result, as the authors show in the book, is technologically the most efficient method in crystal growth, materials processing, and waste treatment. The book gives scientists and technologists an overview of the entire subject including:* Evolution of the technology from geology to widespread industrial use.* Descriptions of equipment used in the process and how it works.* Problems involved with the growth of crystals, processing of technological materials, environmental and safety issues.* Analysis of the direction of today's technology.In addition, readers get a close look at the hydrothermal synthesis of zeolites, fluorides, sulfides, tungstates, and molybdates, as well as native elements and simple oxides. Delving into the commercial production of various types, the authors clarify the effects of temperature, pressure, solvents, and various other chemical components on the hydrothermal processes.
