Book excerpt: Sediment Provenance: Influences on Compositional Change from Source to Sink provides a thorough and inclusive overview that features data-based case studies on a broad range of dynamic aspects in sedimentary rock structure and deposition. Provenance data plays a critical role in a number of aspects of sedimentary rocks, including the assessment of palaeogeographic reconstructions, the constraints of lateral displacements in orogens, the characterization of crust which is no longer exposed, the mapping of depositional systems, sub-surface correlation, and in predicting reservoir quality. The provenance of fine-grained sediments—on a global scale—has been used to monitor crustal evolution, and sediment transport is paramount in considering restoration techniques for both watershed and river restoration. Transport is responsible for erosion, bank undercutting, sandbar formation, aggradation, gullying, and plugging, as well as bed form migration and generation of primary sedimentary structures. Additionally, the quest for reservoir quality in contemporary hydrocarbon exploration and extraction necessitates a deliberate focus on diagenesis. This book addresses all of these challenges and arms geoscientists with an all-in-one reference to sedimentary rocks, from source to deposition. Provides the latest data available on various aspects of sedimentary rocks from their source to deposition Features case studies throughout that illustrate new data and critical analyses of published data by some of the world’s most pre-eminent sedimentologists Includes more than 150 illustrations, photos, figures, and diagrams that underscore key concepts

Download or read book Geochemical Prospecting for Thorium and Uranium Deposits written by R.W. Boyle and published by Elsevier. This book was released on 2013-11-11 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Economic Geology, 16: Geochemical Prospecting for Thorium and Uranium Deposits focuses on the analysis of various geochemical methods applicable in the search for all types of thorium and uranium deposits. The publication first ponders on the general chemistry and geochemistry of thorium and uranium, deposits of thorium and uranium and their indicator elements, and geochemical prospecting for thorium and uranium. Discussions focus on radiation surveys, selection of areas, primary mineralization, supergene oxidation, and secondary enrichment of endogenic thorium and uranium deposits, and equilibrium in the natural radioactive series. The book then ponders on lithochemical, pedochemical, hydrochemical, and biogeochemical surveys of the geochemical prospecting for thorium and uranium. Topics include heavy and light mineral surveys of stream, river, pond, and lake sediments, detailed litochemical surveys utilizing primary halos, and case histories. The text takes a look at sampling procedures and analytical methods for estimating thorium and uranium and miscellaneous methods and atmochemical surveys on the geochemical prospecting for thorium and uranium, including isotopic methods, remote sensing and geothermal methods, and liquid inclusion and thermoluminescent methods. The book is a valuable source of data for researchers wanting to explore geochemical prospecting for thorium and uranium deposits.

This book was released on 2012-12-06 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume are dedicated to Professor Dr. Dr. h.c. G. Christian Amstutz by his colleagues, friends, and students on the occasion of his 60th anniversary. The authors of this book - the theme was restricted to syngenesis and epigenesis in the formation of mineral deposits - wish to honour with their articles a scientist who has contributed to, and substantially promoted the understanding of the genesis of mineral deposits in the last decades. The majority of the articles deal with strata-bound depos its, thus reflecting one of his main scientific interests. In the tradition of his professors, Paul Niggli and Paul Ramdohr, G.C. Amstutz has maintained an open and active interest in many fields of earth science. His numerous papers have triggered a remarkable number of new ideas and investigations in a variety of fields, and the "happy marriage" of economic geology with sedimentology is cer tainly one of his main successes, starting with the first Symposium on Sedimentology and Ore Genesis at the Sixth International Sedimentological Congress at Delft in 1963.
Download or read book The Pyrite Trace Element Paleo Ocean Chemistry Proxy written by Daniel D. Gregory and published by Cambridge University Press. This book was released on 2020-12-24 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the trace element content of sedimentary pyrite as a proxy for the trace element composition of past oceans has recently emerged. The pyrite proxy has several potential advantages over bulk sample analysis: preservation through metamorphism; little dilution during analysis (samples are ablated not dissolved, allowing for the less abundant elements commonly held in the sulfide fraction to be investigated as proxies); accurate measurement of several elements simultaneously; the ability to screen sediments for hydrothermal overprint; and the technique can give information regarding trace element availably at multiple stages of diagenesis. Because of these multiple strengths, the pyrite trace element proxy is a valuable potential addition to the paleo-ocean chemistry tool kit.

Download or read book Geochemical Studies written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical Studies is a collection of papers dealing with ore petrology, particularly on the genesis of ores found in sediments. One paper describes the minor elements in metal deposits in sedimentary rocks, focusing on geochemical work on certain classes of ores in sediments and on the theories of origin of the deposits. With better techniques of microprobe analysis of trace elements, the paper notes that ore deposits in sedimentary rocks can be characterized by their minor element suites. One paper points out that large ore deposits cannot possibly be formed by a migration of substances (known as "negative" diffusion). The paper estimates that the quantities of material that can be accumulated in a sediment horizon with a great affinity for these materials, say in a period of one billion years, will still not be sufficient to produce a large ore deposit. The paper estimates the necessary diffusion coefficients that occur in deep structures, where increased mobilities of various substances occur. Geologists, geochemists, and engineers working with fossil fuels will find the collection highly significant.
