Petrography of Igneous and Metamorphic Rocks

Petrography of Igneous and Metamorphic Rocks
By Anthony R. Philpotts

Publisher: Waveland Pr Inc | 2003 | 192 Pages | ISBN: 1577662954 | PDF | 20.47 MB

This comprehensive laboratory manual teaches students taking their first course in petrography the techniques of describing and classifying rocks as well as how to apply those techniques to common igneous and metamorphic rocks. Essential features include: a listing of common minerals with their most important distinguishing optical properties; over two hundred illustrations detailing the relation between optics and crystal morphology; an accompanying CD-ROM with color slides illustrating rock-forming minerals and the textures of rocks, many with text and audio annotations by the author; descriptions of the textures and structures of igneous and metamorphic rocks; the most important properties of all the minerals compiled in an easy-to-access, full-color table; and a chart for determining the approximate modal (volume) percentage of minerals in rocks. The classification of igneous rocks used in the book is the one proposed by the International Union of Geological Sciences (IUGS) Subcommission of the Systematics of Igneous Rocks. A list of commonly used rock names--many not part of the IUGS classification--is keyed to this classification. Also, the widely used Irvine- Baragar classification of volcanic rocks is included. Dr. Philpotts has organized a large amount of information to be easily and rapidly accessible. He provides students with a concrete foundation, giving them experience and confidence as they encounter the field of petrography.

New Aspects of Mesozoic Biodiversity

New Aspects of Mesozoic Biodiversity
Springer | 2010-07-29 | ISBN: 3642103103 | 185 pages | PDF | 2 MB

The proposed book is an edited volume which contains a thematic set of seven novel papers on contemporary issues of fossil vertebrates that includes new insights of tetrapod evolution during Palaeozoic and Mesozoic eras, discovery of new vertebrate fossils including dinosaur from different continents, new information on palaeo-osteohistology and palaeobiogeography of the Indian plate during the end Mesozoic. All the seven papers of the proposed book are extremely significant in the present milieu of interdisciplinary research in areas covering vertebrate palaeontology, palaeobiology, palaeoecology and palaeobiogeography. This book will give a glimpse of the present day state of the art knowledge of these branches of science. The papers of the proposed book are the results of pioneering researches of the concerned scientists who have excellently presented their ideas/views and new discoveries in their contributions making this book intellectually attractive to the researchers in these fields all over the world. The problems and issues addressed in these papers are of general interest, so this book will not only attract the vertebrate palaeontologists but will also arouse interest of the researchers and professionals dealing with evolutionary biology and biodiversity.

Out of seven papers of the proposed book, the first paper offers most valuable information on the recent major advances in palaeobiological researches on Palaeozoic-Mesozoic vertebrates and includes information on new discoveries filling the gaps in the evolution of higher taxa, application of new techniques such as molecular palaeontology, CT scanning of fossil bones and development of new concepts generating novel hypotheses. In the second paper/chapter a brilliant analysis is made on the evolution, diversification and extinction of the reptilian group, Lepidosauria, with its two major components, Rhynchocephalia and Squamata, since its appearance in the Triassic till today. One of the keystones in the evolutionary history of vertebrates is the new information provided by the discoveries of the new vertebrate fossils from different parts of the world. There are two such papers; one of them includes description of the earliest pterosaur of the world discovered from the Triassic sediments of Brazil while another paper is on the recovery and description of a new abelisaurid dinosaur from India. In the field of vertebrate palaeontology study of bone microstructure is a recent challenging development, which provides substantial information on the palaeobiology of the fossil animals. In one of the papers, the authors described the bone microstructure of a Triassic kannemeyeriid dicynodont from India and deciphered rapid osteogenesis and overall fast growth of the taxon with three distinct ontogenic stages. The penultimate paper/chapter deals with the Late Mesozoic Indian biota, their endemism, cosmopolitanism and evolution in the background of end Cretaceous mass extinction event as well as the extensive Deccan basalt eruption while the last paper/chapter compiles latest information on the tectonic evolution of the Indian plate with its biogeography during the Cretaceous-Tertiary period testing the models of geodispersal and vicariance.

This book will generate interest to professionals, researchers, teachers and graduate students of vertebrate palaeontology, geology and zoology of all the Universities as well as the researchers associated with the Natural History Museums located in different parts of the world. Besides, the academic or professional societies such as Geological Society of London, Palaeontological Association, UK; Society of Vertebrate Paleontology, USA; Palaeontological Society of India, Palaeontological Association, France; Palaeontological Society of China, Palaeontological Association of Australasia will also be interested to keep a copy.

Systematics of magmatic sources in terms of isotope geochemistry in continents and ocean-continent transition zones are covered. Formal mathematical considerations on radiogenic isotope geology that are presented in a simple way with numerical examples and tables that can be used for solutions of theoretical problems on the origin and evolution of the Earth as well as for correct selection of material in regional geochronological studies and dating of individual geological objects.

Aqueous Environmental Geochemistry

Aqueous Environmental Geochemistry By Donald Langmuir
Publisher: Pren tice H a l l 1997 | 600 Pages | ISBN: 0023674121 | PDF | 27 MB

Langmuir provides a thorough presentation of natural chemical concentrations, systems and processes to help readers (1) understand controls on the chemical quality of surface and subsurface waters, and (2) distinguish between the natural and the anthropogenic. Unlike most authors, whose civil/sanitary engineering backgrounds promote a more aquatic chemistry perspective, LangmuirUs geology/geochemistry experience focuses coverage on the chemical interactions between water and geological materials. The book provides valuable training in using in the geochemical computer code MINTEQA2 as an integral problem-solving tool.
