This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!

"The history of Earth's early atmosphere, hydrosphere, and biosphere, from Hadean through Proterozoic time, is one of geology's enduring puzzles. Ore deposits provide important insights into this history because they contain elements and minerals that are highly sensitive to the geochemical environment in which they form. Just what these minerals tell us remains a matter of considerable debate, however. When and how did life develop, an oxygen-rich atmosphere form, and sulfate dominate the ocean? This volume contains reports on these questions from both sides of the aisle for iron and manganese formations, uranium paleoplacers and hydrothermal deposits, and exhalative sulfides and oxides."--Publisher's website.

Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 7: Au, U, Fe, Mn, Hg, Sb, W, and P Deposits focuses on the characteristics, properties, origins, and structures of Au, U, Fe, Mn, Hg, Sb, W, and P deposits. The selection first elaborates on gold in the Proterozoic sediments of South Africa, nature of the Witwatersrand gold-uranium deposits, and origin of Western-States type uranium mineralization. Discussions focus on tectonic conditions, sedimentation, mineralization and alteration, architecture of the Witwatersrand Basin, source of wealth in the Witwatersrand Basin, gold mineralization in South Africa, and ground-rules for gold prospecting. The text then ponders on origin of the Precambrian banded iron-formations, aspects of the sedimentary petrology of cherty iron-formation, and genetic problems and environmental features of volcanosedimentary iron-ore deposits of the Lahn-Dill Type. Concerns cover geological setting, crystallization structures, origin of cherty iron-formations, similarities and differences between banded and oolitic iron-formations, regional geologic distribution, and general diagnostic statement. The manuscript examines sedimentary phosphate deposits, ancient manganese deposits, and freshwater ferromanganese deposits. The selection is a dependable reference for researchers wanting to explore Au, U, Fe, Mn, Hg, Sb, W, and P deposits.

GOLD: History and Genesis of Deposits is the product of an effort by the Society of Economic Geologists to publish materials that will expand knowl edge concerning timely, specific topics important to the study of economic geology and to economic geologists. A volume on gold was selected for a general review-type publication because of the importance of the gold mining industry in the 1980s. The officers and council of the Society of Economic Geologists authorized the preparation of this book on gold in 1981, and Dr. Robert W. Boyle was selected as its author. Dr. Boyle has extensive experience in the study of gold deposits. He has an international reputation and a broad interest and understanding of the gold mining industry, the origin of gold deposits, and the history of gold as a metal and ore from prehistoric times to recent. Dr. Boyle uses important publications on gold deposits as source materials to document the various pathways of geological thought over time to introduce the reader to modern concepts. The book contains a wealth of information concerning gold.
