Beschreibung

Economic Geology focuses not only on the nature and origin of ore deposits but also explores the economic issues that surround the exploitation of mineral resources. Topics of particular focus are the rate of exploitation of natural resources, the question of when or if these resources will be exhausted, the pollution and social disturbance that accompanies mining, the compromises and challenges that arise from the explosion of demand from China, India and other rapidly developing countries, and the moral issues that surround mining of metals in lesser developed countries for consumption in the first-world countries. With its dual character, the book Is useful as an introductory text for students in the earth sciences and a reference volume for students, teachers and researchers of geography, economics and the social sciences.
