Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book Classical Marble Geochemistry Technology Trade written by N. Herz and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marble in Ancient Greece and Rome: Geology, Quarries, Commerce, Artifacts Marble remains the sine qua non raw material of the an cient Greeks and Romans. Beginning in the Bronze Age sculptu re began in marble and throughout classical times the most im portant statues, reliefs, monuments and inscriptions were made of it. Yet, quarry sources changed in time as preferences for different marbles were influenced by local traditions, the pos sibilities of transport, esthetic tastes, and economics. Marble studies and the identification of the provenance of marble can thus reveal much about Greek and Roman history, trade, esthe tics and technology. Persons in many disciplines are studying various aspects of Greek and Roman marble usage. Geologists and geochemists are working on methods to determine the provenance of marble; ar chaeologists are noting changing patterns of import and use in excavation~ and discovering how improving quarrying techniques and prelimihary dressing of the extracted material influenced the final shape of artifacts; ancient historians are now under standing quarry organization and bureaucracies that controlled marble production and trade; art historians are seeing how phy sical characteristics of the stone affected the techniques and style of sculpture; architects and engineers are interested in quarry technologies and usage in building construction. These specialists drawn from many disciplines rarely have an opportu nity to compare notes and see how each can contribute to the research effort of others.

Download or read book G ktepe Marbles written by Donato Attanasio and published by L'Erma Di Bretschneider. This book was released on 2021 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Goektepe marbles, white, black and two-toned, corroborated by archaeological studies and evidences and by scientific archaeometrical studies have been published in several previous paper on the most renowned international journals, but the idea to publish a monographic volume is based on the suggestion that this kind of publication can emphasize the importance of the Goektepe marble, in fact, the new Roman imperial sculptural marble. The large and intensive field research changed completely our knowledge about Roman marble quarries in ancient Asia Minor, due to the unexpected discovery of more than 30 exploitation sites of roman times. The importance of these quarries consists in the fact that the produced marbles were all intended to be export marbles to be destined not only to other foreign cities of the Roman Empire, but mainly to Rome.

Download or read book Economic Geology written by Walter L. Pohl and published by John Wiley & Sons. This book was released on 2011-03-03 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity’s ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance. This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life cycle of a mine and after its closure are addressed, with an emphasis on sustainable and "green" mining. The central scientific theme of the book is to place the extraordinary variability of mineral deposits in the frame of fundamental geological processes. The book is written for earth science students and practicing geologists worldwide. Professionals in administration, resource development, mining, mine reclamation, metallurgy, and mineral economics will also find the text valuable. Economic Geology is a fully revised translation of the the fifth edition of the German language text Mineralische und Energie-Rohstoffe.

Book excerpt: Low-Grade Metamorphism explores processes and transformations in rocks during the early stages of metamorphic recrystallization. There has been little analysis and documentation of this widespread phenomenon, especially of the substantial and exciting advances that have taken place in the subject over the last decade. This book rectifies that shortfall, building on the foundations of Low-Temperature Metamorphism by Martin Frey (1987). The editors have invited contributions from an internationally acknowledged team of experts, who have aimed the book at advanced undergraduate and graduate students as well as researchers in the field.
