Connie May Fowler; C. J. Ebinger; C. J. Hawkesworth, "The Early Earth: Physical, Chemical and Biological Development" Geological Society of London 2003 ISBN: 1862391092 352 pages PDF 37,8 MB
Product Description
This volume contains a series of papers on a wide range of aspects of the early development of the Earth in the first 2000 Ma of Earth’s history, including geophysics, structure and tectonics, atmosphere, origin of life, biosphere, deep mantle geochemistry, early oceans, microbial ecology, the aim being to facilitate discussion and understanding of this area of research. The book is divided into three parts: (1) Geophysical and Petrological Constraints on Archaean Lithosphere: These papers highlight differences in structure and composition of Archaean and post-Archaean lithosphere, with contributions from seismologists, petrologists, and geochemists. Seismic evidence for the formation and evolution of cratons is presented. Shear wave splitting results, petrologic data and crustal deformation fabrics are used to characterize variations of anisotropy in order to investigate the coupling and decoupling of the crust and upper mantle beneath cratons, isotopic data from large cratons suggesting that the lithospheric mantle is the same age as the overlying crust, provide further constraints on the modification of cratonic roots with time. (2) Models of Cratonic Evolution and Modification: These papers focus on global and regional models of cratonic accretion based on evidence from the rock record. Numerical models of cratonic rock both in normal mantle flow and in the presence of plums suggest that cratons decrease in size by lateral erosion rather than by thinning. (3) Constraints on the Archaean Environment: These papers are concerned with the physical, chemical and biological controls on Earth’s surface environment in the late Hadean and the Archaean. Archaean strata record the early biogenic controls on the carbon cycle, and shift to an oxygen-rich atmosphere. The timing of hydrogen loss, carbon-dioxide build-up, the appearance of life, and the origins of photosynthesis are all controversial topics discussed here. Subjects covered include the chemical and biological controls on the atmospheric and oceans, early controls on the carbon cycle and photosynthesis, petrologic, isotopic, tectonic and seismic evidence for the composition and structure of Archaean lithosphere.

Proterozoic East Gondwana: Supercontinent Assembly and Breakup

Proterozoic East Gondwana: Supercontinent Assembly and BreakupGeological Society of London 2003-09 ISBN: 1862391254 440 pages PDF 55 MB
This volume as a whole focuses on Late Mesoproterozoic to early Cambrian events related to Gondwanaland assembly. The 19 papers provide a comprehensive review including advanced knowledge and new data from all critical areas of east Gondwanaland. The recent knowledge of the evolution of East Gondwana which was regarded as an integral part of Mesoproterozoic super-continent Rodinia is the major theme of the volume, which is reinforced by highlighting this radical and new understanding of the evolution of East Gondwana. This volume is of use as both a text and reference book for Earth Science postgraduates, and of appeal worldwide to professional geologists with an interest in Rodinia and Gondwana.

Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives

Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives Publisher: Geological Society of London Pages: 424 2003 ISBN 1862391173 PDF 35 MB

The motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes. They are a mixture of review papers on selected topics in the field of structural geology and tectonics and papers on current issues and new techniques and are grouped into four themes: The effect of fluids on deformation; The interpretation of Microstructures and textures; Deformation mechanisms and rheology of crust and upper mantle minerals; Crust and lithosphere tectonics.

Coastal Processes with Engineering Applications

Coastal Processes with Engineering ApplicationsPublisher: Cambridge University 488 pages March 25, 2004 ISBN 0521602750 PDF 8 MB
The world's coastlines, dividing land from sea, are geological environments that are unique in their composition and the physical processes affecting them. At the dynamically active intersection of land and the oceans, humans have been building structures throughout history. Initially used for naval and commercial purposes, more recently recreation and tourism have increased activity in the coastal zone dramatically. Shoreline development is now causing a significant conflict with natural coastal processes. This text on coastal engineering will help the reader understand these coastal processes and develop strategies to cope effectively with shoreline erosion. The book is organized in four parts: (1) an overview of coastal engineering, using case studies to illustrate problems; (2) hydrodynamics of the coastal zone, reviewing storm surges, water waves, and low frequency motions within the nearshore and surf zone; (3) coastal responses including equilibrium beach profiles and sediment transport; (4) applications such as erosion mitigation, beach nourishment, coastal armoring, tidal inlets, and shoreline management.

Elsevier's Dictionary of Chemoetymology: The Whies and Whences of Chemical Nomenclature and TerminologyElsevier Science ISBN:0444522395 Edition - 2006-12-19 PDF 448 pages2.23 MB Rapidshare & Aliceinwire
Noting a marked lack of comprehensiveness and/or contemporaneity among typical reference works on chemical etymology, as well as a somewhat spotty coverage of chemical terms and their etymology in comprehensive dictionaries and textbooks the author decided to write an up-to-date desk reference on chemical etymology which would satisfy the needs of casual readers as well as those of more demanding users of etymological lore. Characteristic user-friendly features of the present work include avoidance of cumbersome abbreviations, avoidance of entries in foreign alphabets, and a broad coverage of all chemical disciplines including mineralogy. Biological, medical, geological, physical and mathematical terms are only considered where they appear of interest to mainstream chemists.This book does not provide definitions of terms (unless required in the etymological context) nor guidance as to the timeliness of different nomenclature systems. The typical user will from the outset be well aware of the exact meaning of the terms he or she focuses on and only require the etymological background to be used. Examples of sources which have been drawn upon in the preparation of this book, apart from the extremely useful Internet resource Google, are listed, but an exhausting enumeration would be tiresome and impractical.

Microtectonics deals with the interpretation of microstructures, small-scale deformation structures in rocks that yield abundant information on the history and type of deformation and metamorphism. The results are used by geologists to obtain data for large-scale geological interpretations. This advanced textbook treats common microstructures such as foliations, porphyroblasts, veins, fringes and shear sense indicators. The book mainly focusses on optical microscopy as a tool to study microstructures, but also describes other techniques such as EBSD and tomography. Many photographs and explanatory drawings clarify the text. The new edition, substantially revised throughout and extended, features two new chapters (primary structures and experimental microstructures), 68 new figures, more than 800 new references.
