This book is a comprehensive overview of economic geology for the general geologist and anyone else interested in the minerals industry and the global supply of raw materials. It includes some thought-provoking statements and questions for discussion on globalisation and current practices in the minerals industry. In the second edition, all chapters have been extensively revised, and a new author has been added to increase coverage of some mineral deposits and topics. The economic issues surrounding the exploitation of mineral resources is discussed in three of the six chapters of the book. It deals with issues that are commonly addressed in current science reporting - 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 in 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. The book will be useful both 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.
