Available in PDF, EPUB and Kindle. Book excerpt: Tis text has resulted from some forty years of experience during which the author has puzzled over the meaning of ore textures. Te learning process has been slow and is still incomplete. Te bemusement began directly upon leaving the academic confnes, which in retrospect lef one keen young geologist very ill-equipped to interpret the mineralising process via feld or hand lens style observation of the rocks. Enlightenment has proceeded via a series of events:- 1. Te slow process of feld observation as an industry-based mine and exploration geologist. 2. Te opportunity to visit numerous diferent styles of ore deposit both as an academic and consultant. 3. Te need to answer questions from several generations of enquiring students. 4. Te privilege of being able to conduct research. 5. Te good fortune to be associated with a few top class economic geologists who actually knew what they were doing! Professor Willard C. Lacy deserves the most credit for quietly demonstrating the value of frst principles concerning fuid channelways, combined with an ability to look properly at the t- tures. Despite rapid technological advances this skill remains fundamental both to the practi- ing exploration geologist and to the academic researcher who is interested in understanding ore forming processes. Te fve volumes comprising this presentation were originally compiled individually over a period of eleven years, and aimed to progressively guide the observer though the principles of recogn-i tion concerning infll, alteration, overprinting, and fnally to ore-related breccias.

This book was released on 2013-10-02 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotated Bibliographies of Mineral Deposits in Africa, Asia (Exclusive of the USSR) and Australasia brings together annotated bibliographies of mineral deposits in Africa, Asia (with the exception of the USSR), and Australasia. Each bibliography is followed by notes to show the deposit's location; geological framework; age and type; structural and stratigraphic relations; conditions of formation; and position in the modified Lindgren classification. Comprised of 25 chapters, this volume begins with an introduction to the more important sources of references in the bibliographies, set down in alphabetical order with the number of references provided by each source. The distribution of deposits by continent and country follows. The deposits include molybdenum, nickel, copper, lead, and tin. Eruptive rocks, the metamorphic cycle, and the mineralization process are addressed, along with liquid immiscibility between silicate magmas and sulfide melts; the geology, mineralogy, and petrology of ore deposits in various mines; and the significance of mineralized breccia pipes. This book will be of value to mineralogists, geologists, and earth and mineral scientists as well as students interested in ore deposits.

Download or read book Giant Metallic Deposits written by Peter Laznicka and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals in the earth's crust are very unevenly distributed and, traditionally, a small number of ore deposits, districts or countries have dominated the world supply and have influenced commodity prices. The importance of exceptionally large, or rich, deposits has greatly increased in the age of globalization when a small number of international corporations dominate the metals market, based on few very large ore deposits, practically anywhere in the world. Search for giant orebodies thus drives the exploration industry: not only the in-house teams of large internationals, but also hundreds of junior companies hoping to sell their significant discoveries to the "big boys". Geological characteristics of giant metallic deposits and their setting and the politico-economic constraints of access to and exploitation in prospective areas have been a "hot topic" in the past fifteen years, but the knowledge generated and published has been one-sided, scattered and fragmented. This is the first comprehensive book on the subject that provides body of solid facts rather than rapidly changing theories, written by author of the Empirical Metallogeny book series and founder of the Data Metallogenica visual knowledge system on mineral deposits of the world, who has had an almost 40 years long international academic and industrial experience. The book will provide abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants", and some inspiration for commodity investors.
