Download or read book A Practical Guide to Ore Microscopy Volume 1 written by Ricardo Castroviejo and published by Springer Nature. This book was released on 2023-07-12 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a guide to the microscopic study of metallic ores with reflected light. It combines a rigorous approach with an attractive and easy-to-follow format, using high-quality calibrated photomicrographs to illustrate the use of color for ore identification. The ore identification methodology is updated with systematic color analysis and the application of new multispectral reflectance datasets, which offer an efficient tool for automated ore characterization. In addition, the first volume of this two-part work discusses the essential gangue minerals. Readers will gain familiarity with the method as they follow its application to over 200 selected minerals, comprising the most important ore (≈150) and gangue (≈50) minerals, which are described in the text. Each entry includes an explanatory text with corresponding color photomicrographs for each of the most common microscope settings, preceded by a table summarizing the ore’s main properties, and followed by spectral information in the visible and near-infrared ranges (specular reflectance values from 370 to 1000 nm). Some uncommon, strategic ores, e.g. columbotantalite (“coltan”) and monazite, receive particular attention or are described for the first time with reflected light. Lastly, the book presents a learning strategy for beginners and students. The approach is essentially practical, focusing on the development of observation skills, including self-checking through proposed practical tasks. In addition, the traditional use of determinative tables is critically reviewed and updated. This book is part of a two-volume work. The second volume focuses on intergrowths/textural analysis and interpretation, as well as computer-vision-based automation and applications to ore processing/geometallurgy. The intended audience includes professionals and engineers dealing with mineral resources, as well as postgraduate students. The book also provides lifelong learning support for freelancers and a valuable reference resource for practical university teaching.
Download or read book The Ore Minerals Under the Microscope written by Bernhard Pracejus and published by Elsevier. This book was released on 2008-11-11 with total page 895 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is a very detailed ore microscopy atlas in colour, containing observations for some 430 minerals (mostly opaques and a few gangue minerals). Its main emphasis lies on the display of the respective mineral's most important optical properties (shown in up to 5 high-quality photos for each mineral with scale). The colour plates are supplemented by brief tabulated data, such as name and synonyms, mineral group, chemical composition, major formation environment, reflection colour/shade, and reflectivity. Wherever reflectivity data were not available, the respective value was estimated on the basis of some 4 common/standard minerals of a similar colour or grey shade."--BOOK JACKET.

Book excerpt: The study of ancient metals in their social and cultural contexts has been a topic of considerable interest in archaeology and ancient history for decades, partly due to the modern dependence on technology and man-made materials. The formal study of Archaeometallurgy began in the 1970s-1980s, and has seen a recent growth in techniques, data, and theoretical movements. This comprehensive sourcebook on Archaeometallurgy provides an overview of earlier research as well as a review of modern techniques, written in an approachable way. Covering an extensive range of archaeological time-periods and regions, this volume will be a valuable resource for those studying archaeology worldwide. It provides a clear, straightforward look at the available methodologies, including: • Smelting processes • Slag analysis • Technical Ceramics • Archaeology of Mining and Field Survey • Ethnoarchaeology • Chemical Analysis and Provenance Studies • Conservation Studies With chapters focused on most geographic regions of Archaeometallurgical inquiry, researchers will find practical applications for metallurgical techniques in any area of their study. Ben Roberts is a specialist in the early metallurgy and later prehistoric archaeology of Europe. He was the Curator of the European Copper and Bronze Age collections at the British Museum between 2007 and 2012 and is now a Lecturer in Prehistoric Europe in the Departm ent of Archaeology at the Durham University, UK. Chris Thornton is a specialist in the ancient metallurgy of the Middle East, combining anthropological theory with archaeometrical analysis to understand the development and diffusion of metallurgical technologies throughout Eurasia. He is currently a Consulting Scholar of the University of Pennsylvania Museum, where he received his PhD in 2009, and the Lead Program Officer of research grants at the National Geographic Society.

This book was released on 2007-10-31 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though an enormous amount of information relating to earth sciences are available on the Internet, for a serious researcher, teacher, librarian or a student who has deadlines to meet, searching the Internet for specific scientific information can at times be frustrating. The main purpose of Online Databases and Other Internet Resources for Earth Science is to group these resources together and to provide the URLs and hyperlinks so a researcher, teacher or student can access them with the minimum effort, time and cost. The book also introduces the reader to a few basic concepts that propel the Internet and the world wide web so that he or she can make informed searches apart from assessing the quality and reliability of the data available on the internet. A brief introduction is provided on the current status of the draft treaty by the World Intellectual Property Organization (WIPO) and the EU directive on copyright restrictions for scientific databases and what a researcher is permitted to do with the data obtained from the Internet, especially those from a commercial data provider. - Earth science resources on the Internet are grouped into various categories: such as journals, databases, multimedia, directories, teaching aids and mailing lists - Online earth science publications and a list of open access publications related to earth sciences - The databases are further grouped into bibliographic data, specimen collection, chemical analysis, geophysical data, etc.

Download or read book The Use of Palaeomagnetism and Rock Magnetism to Understand Volcanic Processes written by M.H. Ort and published by Geological Society of London. This book was released on 2015-04-09 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a synopsis of current research on volcanic processes, as gained through the use of palaeomagnetic and rock magnetic techniques. Thermoremanent magnetization information provides a powerful means of deciphering thermal processes in volcanic deposits, including estimating the emplacement temperature of pyroclastic deposits, which allows us to understand better the rates of cooling during eruption and transport. Anisotropy of magnetic susceptibility and anisotropy of remanence are used primarily to investigate rock fabrics and to quantify flow dynamics in dykes, lava flows, and pyroclastic deposits, as well as identify vent locations. Rock-magnetic characteristics allow correlation of volcanic deposits, but also provide means to date volcanic deposits and to understand better their cooling history. Because lava flows are typically good recorders of past magnetic fields, data from them allow understanding of changes in geomagnetic field directions and intensity, providing clues on the origin of Earth’s magnetic field.

Available in PDF, EPUB and Kindle. Book excerpt: The New Walford highlights the best resources to use when undertaking a search for accurate and relevant information, saving you precious time and effort. For those looking for a selective and evaluative reference resource that really delivers on its promise, look no further. In addition to print sources, The New Walford naturally covers an extensive range of e-reference sources such as digital databanks, digital reference services, electronic journal collections, meta-search engines, networked information services, open archives, resource discovery services and websites of premier organizations in both the public and private sectors. But rather than supplying a list of all available known resources as a web search engine might, The New Walford subject specialists have carefully selected and evaluated available resources to provide a definitive list of the most appropriate and useful. With an emphasis on quality and sustainability, the subject specialists have been careful to assess the differing ways that information is framed and communicated in different subject areas. As a result the resource evaluations in each subject area are prefaced by an introductory overview of the structure of the relevant literature. This ensures that The New Walford is clear, easy-to-use and intuitive. - Publisher.
