Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Deposits of the Useful Minerals Rocks, Vol. 2: Their Origin, Form, and Content I have gratefully to acknowledge the several helpful reviews upon Vol. I. Of this translation. It has been suggested 1 that it would have been better not to have used eruptive as synonymous with igneous, but rather with volcanic. That is a suggestion which many would urge. The authors, however, whose views I am representing, actually use eruptive. Moreover, this term, in association with sedimentary as counterpart, is common among both British and American authorities. Geikie, for instance, in his text-book of Geology' gives eruptive undoubted preference over igneous, and, accord ing to him,2 the eruptive rocks include both the plutonic and the volcanic. It appeared to me also that in, discussing ore-deposits the term eruptive assisted in conveying the idea of the part played by material coming upwards through the crust. The term sedimentary, its counter part, similarly conveyed the idea of settlement upon the crust. In these two words we therefore have the magmatic and meteoric sources of ore deposits suggested. The term igneous, properly speaking, should have aqueous for counterpart, these two terms suggesting the elements fire and water respectively, a suggestion less pertinent than the one above. F. L. Ransome regrets the confusion in the English and American terms for the principal oxidized zinc ores. To avoid this confusion I have adopted a suggestion by Prof. Cullis, and described these ores as zinc carbonate and zinc hydrosilicate respectively, and the mixture of the two as zinc oxidized ore.

This book was released on 2016-06-25 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Igneous Rocks and Iron Ores of Kiirunavaara, Luossavaara and Tuolluvaara The region examined by the writer comprises the two ore mountains Kii runavaara and Luossavaara and the continuation towards the sides and north ward of the igneous rocks forming their slopes, further on, the ore mountain Tuolluvaara and some exposures located chie y north of the latter and con sisting of rocks more or less closely related to the ore-bearing ones. The object of the work was to make an exhaustive analysis of the petrographic characters of the igneous rocks and ores in question, and to explain the mutual relations of the different rock varieties as well as their relations to the ores. In this way one might expect to get a better insight into the mode of origin of the iron ores of the region. The ore problem is naturally the most interesting one in this region, but there are also, in the writer's field of work, as well as in the neighbouring regions, other phenomena of great interest.

Download or read book The Ore Deposits of the United States written by James Furman Kemp and published by Forgotten Books. This book was released on 2015-06-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Ore Deposits of the United States The following pages presuppose for their comprehension some acquaintance with geology and mineralogy. The materials for them have been collected and arranged in connection with lectures on economic geology, first at Cornell University and later at the School of Mines, Columbia College. To the descriptions of others the author has endeavored to add, as far as possible, observations made by himself in travel during the last ten years. The purpose of the book is twofold, and this fact has been conscientiously kept in view. It is, on the one hand, intended to supply a condensed account of the metalliferous resources of the country, which will be readable and serviceable as a text-book and work of reference. For this reason every effort has been put forth to make the bibliography complete, so that, in cases where fuller accounts of a region are desired, the original sources may be made available in any good library. But, on the other hand, it has also been the hope and ambition of the author to treat the subject in such a way as to stimulate investigation and study of these interesting phenomena. If, by giving an extended view over the field, and by making clear what our best workers have done in late years toward explaining the puzzling yet vastly important questions of origin and formation, some encouragement may be afforded those in a position to observe and ponder, the second aim will be fulfilled. In carrying out this purpose, the best work of recent investigators on the origin and changes of rocks, especially as brought out by microscopic study, has been kept constantly in mind, and likewise in the artificial production of the ore and gangue minerals. So much unsound and foolish theorizing has been uttered and believed about ores, that too much care cannot be exercised in basing explanations on reasonable and right foundations.

Download or read book Introduction to the Study of Igneous Rocks Classic Reprint written by George Irving Finlay and published by Forgotten Books. This book was released on 2015-07-27 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Introduction to the Study of Igneous Rocks The plan of the present work is that of selecting from the large body of observed facts bearing on the identification of rocks with the microscope those which it is desirable for the beginner to get command of in the course of his early studies. The work is intended as an introduction to the exhaustive treatises on the subject. Inasmuch as the student invariably begins his laboratory work with the igneous rocks, these alone, with their constituent minerals, have been considered. Such a method of attack at once greatly limits the field on its mineralogical side, and permits of an extended treatment of determinative methods. In the discussion of the characteristics of a given rock-making mineral the aim has been to impart at the outset the most important diagnostic information regarding it. In the tables for desk use a fairly extended enumeration of the properties of the minerals of igneous rocks is given, but here also emphasis has been laid, by the use of bold face type, upon their more important characteristics from the point of view of the beginner who has to learn to identify them. The text dealing with the igneous type rocks is devoted entirely to setting forth the assemblages of facts of discriminative significance which are made use of in recognizing them in thin sections. Such a treatment can make no claim to completeness of exposition from the point of view of the geologist. The student will not, however, come to regard rocks merely as objects which can be classified by the recognition of their mineralogy and structures. It is believed that by emphasizing their differences the beginner can most quickly be put in possession of a knowledge of their complexity, and be led to take the interest in them which the petrologist must feel.

This book was released on 2008-01-08 with total page 1580 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 1965, a small group of European economic geologists gathered in Heidelberg, Germany, at the invitation of Professor G. C. Amstutz and decided to establish the Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be called Mineralium Deposita. The first issue of the journal came out in May 1966, and has now matured to a leading journal in economic geology The first Biennial SGA Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London (United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002, th the SGA Council decided that its 8 Biennial Meeting in 2005 should be held in Beijing, China, making this the first Biennial Meeting to be convened outside - th rope. Significantly, 2005 also marks the 40 anniversary of the SGA. The decision to host this year’s premier meeting in Beijing reflects the Society’s successful transition from its traditional European focus to a truly global organization, with 24% of SGA members situated in North America, 13% in Australia and Oceania, and 5% in Asia. Over the last 27 years China has made dramatic progress towards political and economic reform, and opening the nation to the outside world. China’s rapid e- nomic development demands increasing amounts of minerals, fuels and materials, and this is currently a major driver for the global economic markets.

Book excerpt: 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.
