DOWNLOAD EBOOK'What are we going to do with a parcel of old stones?' wrote the director of an African museum a century and a half ago, when one of my ancestors presented him with a splendid collection of fossils of mammal-like reptiles. Old stones, however intriguing, are difficult to interpret, dusty, and do not fit well in the neatly ordered contents of a house of learning. Archaean geology, which is the study of the Earth's history in the period from after 9 the end of planetary accretion (4.5-4.4 x 10 years ago) up to the beginning 9 of the Proterozoic (2.5 x 10 years ago) is much the same - a parcel of old stones seemingly impossible to understand. Yet these stones contain the history of our origins: they can tell us a story that is interesting not just to the geologist (for whom this book is primarily written) but instead addresses the human condition in general.

DOWNLOAD EBOOKMuch new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.

DOWNLOAD EBOOKThis book is a substantially updated, revised and extended version of the book Volcanic Successions, published by Cas and Wright back in 1987. Divided into six major parts, it offers comprehensive information on magma properties; fragmentation processes; subaerial and subaqueous lava types and field textures; sub-volcanic intrusions; explosive or pyroclastic eruptions and deposits; surface sedimentary processes; hydrothermal alteration and lithification, and effects on volcanic rock textures; terminology and approaches to describing and mapping volcanic rocks and terrains; geology of volcanoes and facies models; volcanism and tectonic setting; and to conclude, volcanic-hosted resources. It is a highly up-to-date text, presenting a coherent flow of topics, together with excellent visual material to illustrate key points and deposit features. The new authorship team consists of Ray Cas, Guido Giordano and John Wright, all of whom have extensive experience across the complete spectrum of volcanological processes and deposit types discussed in this exciting new book. The authors approach the diversity of products in volcanic terrains as facies, and use facies analysis and interpretation as a means of constructing facies models for different volcanic settings and their resources. The book is intended as a textbook and research reference book for senior undergraduate and graduate students, researchers and professionals alike.

DOWNLOAD EBOOKThis book is the first comprehensive compilation of data and ideas relating to the origin, evolution, and significance of the world's greenstone belts, and includes contributions from over 100 experts. In the first of two parts, reviews are presented on broad topics relating to the geology of greenstone belts and their surroundings, covering mainly post-1980 research. These include: historical, sedimentologic, volcanic, structural, metamorphic, metallogenic, and thermal aspects; summaries of mafic/ultramafic magnetism, strain, fluids, geophysics and deep structures; relations with associated granitoids, tectonic evolution, and geochronology; and field relationships. The second part takes a more focused look at the geology of specific cratons and individual greenstone belts worldwide, including Archaean, Proterozoic, and Phanerozoic examples. Detailed geologic maps on large and small scales, extensive tabulations of data, and short written summaries of the salient features are included for all belts. The book will be a valuable reference tool for academic and industrial researchers, students, explorationists, and anyone interested in the evolution of Earth processes over geologic time.

DOWNLOAD EBOOKLarge igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3. They are linked to continental break-up, global environmental catastrophes, regional uplift and a variety of ore deposit types. In this up-to-date, fascinating book, leading expert Richard E. Ernst explores all aspects of LIPs, beginning by introducing their definition and essential characteristics. Topics covered include continental and oceanic LIPs; their origins, structures, and geochemistry; geological and environmental effects; association with silicic, carbonatite and kimberlite magmatism; and analogues of LIPs in the Archean, and on other planets. The book concludes with an assessment of LIPs' influence on natural resources such as mineral deposits, petroleum and aquifers. This is a one-stop resource for researchers and graduate students in a wide range of disciplines, including tectonics, igneous petrology, geochemistry, geophysics, Earth history, and planetary geology, and for mining industry professionals.
