The present volume Stratabound Ore Deposits in the Andes has its roots in an international seminar on stratabound ore deposits which took place in September 1986 in Cusco, Peru, sponsored by Multi ciencias (Peru) and UNESCO. During this seminar it became clear that the amount and quality of research done on stratabound ore deposits in the Andes required a synthesis. Researchers in industry and government as well as in academia, including many which had participated at the Cusco Seminar, were invited to contribute. The answer was extremely positive, confirming the idea that a book expressing the state of the art of the study of stratabound ore deposits in the Andes was long overdue. As editors we sought to give maximum coverage to the present knowledge, yet keeping the length, and thereby the price, within rea sonable limits. The book contains three types of contributions. In the first part the reader will find review papers focusing on ( 1) the geologic framework (Frutos), (2) the metallogenesis in Andean countries including also types of deposits differing from those of stratabound nature (Cardozo and Cedillo, Oyarzun), and (3) an in troductory overview of the stratabound ore deposits in the Andes, emphasizing their geotectonic position as a classification tool (Font bote).

The Joint 6th Biennial SGA-SEG Meeting was held in Krakow in August 2001. This volume contains 274 extended abstracts, grouped thematically under 18 session titles covering topics such as lead-zinc deposits; metamorphism affecting mineral deposits; and the environmental aspects of mining.

Geophysical data relating the dynamic processes of plate motion and subduction to Andean orogenesis are interpreted in terms of a new model for magmatic and tectonic development of the central Andes. The model is based on changing subduction geometry - from normal to flat to normal - and the attendant magmatic and tectonic effects of slab dewatering, continental lithospheric hydration, and asthenospheric flow during closing and opening of the subduction zone mantle wedge.

The problem of time-and strata-bound formation of ore deposits has during the past decade become one of the most debated topics in cur rent international discussion. Due to the amazing results of modern mineral exploration and world-wide geophysical research, the mutual relationship between the complex geological history pf a crustal seg ment and the development of distinct metallogenic provinces (ore belts) has received much interest. Reviewing the earth's history in this light one can now recognize metallogenic epochs even of global range which document the existence of world-wide time-bound ore enrich ments. The knowledge of these metallogenetic processes has been growing step by step for several decades. It began with simple observations and sceptic interpretations, which at first threw heretical spot lights on to the edifices of the prevailing theories on granitic differentiation as the favoured source of ore deposits. It was obvious that the new ideas at first referred to ore enrichments in sedimentary sequences, nowadays summarized under the term strata-bound, and mainly interpreted as stratiform or sedimentary ore deposits. Moreover, the modern term "strata-bound" also includes ore mineralizations which are bound to distinct units of layered (intrusive or extrusive) igneous complexes as a general descriptive term without genetical restriction! Albert Maucher is one of the representatives of the initial era who discussed these genetical questions critically in the decade before the 2nd World War.

Sediment-hosted deposits are the main source of zinc and lead. In this volume, the reader will find the most recent developments in research including: - Fluid migration leading to formation of Zn-Pb ores in sedimentary basins. Relationships to orogenic events and to geothermic anomalies - Transport of metals and precipitation mechanisms. The role played by fluid mixing, fluid-rock reaction, organic matter, and thiosulfates - Paleomagnetic dating of ore deposits - The association of Mississippi Valley-type ore deposits to diapiric salt structures - Geochemical investigations applied to exploration for sediment-hosted Zn-Pb deposits - Economic aspects. The broad geographical coverage is an additional aspect which will interest both researchers and explorationists.

Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges. Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level. This book provides information on hazard assessment and remediation of the disturbed environment, including stabilization of contaminated soils and phytoremediation, and will help scientists and public authorities formulate answers to the daily challenges related to the restoration of contaminated land. Provides a thorough overview of the processes operating on mining-devastated areas, as well as origin, distribution, and deactivation of harmful elements Includes outcomes and recommendations of the Global Mining Initiative that are widely regarded as the code of conduct in the minerals industry Contains global case studies that elucidate various aspects of assessment and restoration of mine-contaminated land

This book is the first comprehensive account in English of the geology of Chile, providing a key reference work that brings together many years of research, and written mostly by Chilean authors from various universities and other centres of research excellence. The 13 chapters begin with a general overview, followed by detailed accounts of Andean tectonostratigraphy and magmatism, the amazingly active volcanism, the world class ore deposits that have proven to be so critical to the welfare of the country, and Chilean water resources. The subject then turns to geophysics with an examination of neotectonics and earthquakes, the hazardous frequency of which is a daily fact of life for the Chilean population. There are chapters on the offshore geology and oceanography of the SE Pacific Ocean, subjects that continue to attract much research not least from those seeking to understand world climatic variations, and on late Quaternary land environments, concluding with an account examining human colonization of southernmost America. The geological evolution of Chile is the c. 550 million year history of a continental margin over 4000 km long. During his voyage on H.M.S. Beagle, an extended visit to Chile (1834-35) had a profound impact on Charles Darwin, especially on his understanding of volcanoes, earthquakes and tsunamis.
