Sedimentary Rocks in the Field
Author: Dorrik A.V. StowPublisher: Gulf Professional Publishing
ISBN: 9780123694515
Category : Science
Languages : en
Pages : 328
Book Description
Sediments and sedimentary rocks cover 70% of the Earth's surface, and make up a significant portion of the geological record. Understanding the processes (physical, chemical and biological) that lead to formation of sedimentary material is key in disciplines ranging from geology to environmental science to archaeology. But before interpretation must come observation and identification: Stow's Field Guide is a must-have for this distinctly visual process Professor Stow has culled his extensive research experience into a succinct guide designed for students and professionals in geophysics, geochemistry, paleontology, soil sciences, environmental sciences and more. Sections on field techniques and reader-friendly descriptions also make this guide accessible to amateur geologists. * More than 400 color photographs and diagrams * Extensive cross-referencing for ease of use in the field * Examples from more than 30 countries * Focus on economic applications
Chemical Petrology
Author: R.F. MuellerPublisher: Springer Science & Business Media
ISBN: 146129889X
Category : Science
Languages : en
Pages : 407
Book Description
Chemical petrology is essentially the physical chemistry of rocks and associated fluids, although it also borrows heavily from such other sciences as mineralogy. In terms of fundamentals it is firmly grounded in chemical thermodynamics and kinetics. In its treatment of terrestrial environments it grades imperceptably into sedimentology, geochemistry, and geophysics and in extraterrestrial environments into cosmochemistry. It is one of the most important branches of planetology and meteoritics. The unity of approach of thermodynamics and kinetics to processes in these diverse environments is stressed in this book by numerous examples which have been chosen to illuminate different aspects of the subject. Thus we have discussed in some depth such problems as the genesis of layered basic complexes, calc-alkaline batholiths, chondri tic meteorites, and the surface-atmosphere interaction of the planet Venus because these are important and because they are particularly good illustrations of the chemical petrology approach. Considerable attention also has been devoted to volcanic processes. In our treatment of metamor phism in particular, an attempt has been made to correlate and integrate the vast number of recent experimental, theoretical, and field studies. However, we have not attempted a comprehensive survey of all known rock types or occurrences, nor did we review all the diverse opinions and conclusions on the origins of controversial rocks. Instead we have chosen to stress interpretations we regard as following most directly from the evidence.
Atlas of Mylonites - and related microstructures
Author: Rudolph A. J. TrouwPublisher: Springer Science & Business Media
ISBN: 3642036082
Category : Science
Languages : en
Pages : 306
Book Description
Mylonites form in response to high rates of strain within deep ductile shear zones, which are the extensions at depth of surface faults, thrusts and fault breccias, They can have many different mineralogical compositions and are therefore defined on their textural appearance. This atlas provides high definition images of a large number of different mylonites allowing students and geologists to correctly classify them with greater ease. It also provides insights into the interpretation of mylonitic fabrics to answer questions such as; from what type of rock did this mylonite derive? What were the metamorphic circumstances during mylonitization? What was the intensity of deformation?, and What was the sense of shear? This book will complement the very successful textbook "Microtectonics" by Passchier and Trouw.

Principles of Igneous Petrology
Author: S. MaaloePublisher: Springer Science & Business Media
ISBN: 3642493548
Category : Science
Languages : en
Pages : 388
Book Description
Igneous petrology was to some extent essentially a descriptive sci ence until about 1960. The results were mainly obtained from field work, major element analyses, and microscopical studies. During the 1960's two simultaneous developments took place, plate tectonics became generally accepted, and the generation of magmas could now be related to the geodynamic features like convection cells and subduction zones. The other new feature was the development of new analytical apparatus which allowed high accuracy analyses of trace elements and isotopes. In addition it became possible to do ex perimental studies at pressures up to 100 kbar. During the 1970's a large amount of analytical data was obtained and it became evident that the igneous processes that control the compositions of magmas are not that simple to determine. The composition of a magma is controlled by the compositions of its source, the degree of partial melting, and the degree of fractionation. In order to understand the significance of these various processes the relationship between the physical processes and their geochemical consequences should be known. Presently there are several theories that attempt to explain the origin of the various magma types, and these theories can only be evaluated by turning the different ideas into quantitative models. We will so to speak have to do some book keeping for the various theories in order to see which ones are valid. the present book is intended as an introduction to the more fun damental aspects of quantitative igneous petrology.
