Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses ofall major aspects ofgold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.

Ecological Management of Mining: Achieving Environmental Compliance is a study and comparison - global in scope - of current practices used by mining firms striving for ecological management. The author takes an integrated and interdisciplinary approach in addressing, analyzing and working towards solutions regarding the complex challenges posed by managing the environmental impacts of mining. The issues addressed range from the ecotoxicological effects of metal residues to the land use effects of mining and from socioeconomic impacts to environmental regulation. The goal of this book is to assist mining companies throughout the world to achieve environmental compliance and improve competitiveness in the context of growing environmental regulation and technological innovation. It is an essential book for the wide variety of professionals working on issues in mining. Like the book and the research itself, the audience is integrated and interdisciplinary including engineers, planners, ecologists, policy makers and economists. Features

Remediation and Management of Degraded Lands presents the program of the first International Conference on the Remediation and Management of Degraded Lands. This collection reviews the extent of resource debasement and offers solutions for their restoration. The 14-part first section deals with mine management and rehabilitation. Topics include the devastating results of open-cut mining, open-pit mining, lignite surface mining and acid mining. Despite such ruin, the articles reveal the possibilities for reclamation. Part two devotes nine chapters to the management of derelict lands. Reforestation, soil fertility prognosis, and the uses of nitrogen are just a few of the covered subjects. This portion of the book pays special attention to the successful results of remediation in China and Hong Kong. The final division addresses soil contamination and reclamation. There are eleven chapters on subjects that include the single and interactive effects of aluminum, the effectiveness of EDTA/HCI and the value of pig-on-litter compost as a tool for edible crop growth. These and other innovative techniques make Remediation and Management of Degraded Lands a valuable addition to any environmental library.

This collection of papers from the 2001 TMS Annual Meeting held in New Orleans focuses on five issues concerning cianide: production and uses, processing practices and innovations, recovery and destruction, fundamentals and alternatives. There is also a section about the environmental movement.
