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.

Regional Studies is a collection of papers that deals with strata-bound mineral deposits in the Eastern Alps, in the Canadian Cordillera, in north-central, and southwest England. Other papers describe southern African stratiform ore deposits and the genesis of Irish base-metal deposits. One paper compares the various types of volcanogenic mineral deposits and their depositional environments characterized by distinct assemblages of volcanic rocks, which formed in the Northern Appalachians during certain episodes of the tectonic evolution. The paper notes that the youngest volcanogenic deposits of economic interest are tungsten—molybdenum—tin—bismuth base metal deposits in highly altered rhyolitic sub-volcanic complexes at Mount Pleasant, New Brunswick. Another paper reviews the mineral occurrences in southern Africa that include stratiform, non-magmatic, ore deposits, The paper considers a subdivision of deposits formed from surficial chemical processes during previous (or current) cycles of weathering and erosion. Many ore bodies have a dual origin: for example, the iron in the high-grade hematite deposits is partly syngenetic and partly epigenetic. The paper also illustrates the time-dependence of some stratiform ore deposits in southern Africa in a schematic diagram. Geologists, researchers, or engineers whose works are related with ore deposits and mining will benefit tremendously from the collection.

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).

This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits. Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience. Because of my orientation, the treatment given is perhaps more sedimentological than is usually found in books on ore deposits, but I hope that this proves to be an advantage. It will also be obvious that I have drawn heavily on the ideas and techniques of Robert Garrels. A number of people have helped with the creation of this book. I am especially grateful to my students and colleagues at Cincinnati and The Memorial University of Newfoundland for suffering through preliminary versions in my courses. I particularly thank Bill Jenks, Malcolm Annis, and Dave Strong. For help with field work I thank A. Hallam, R. Hiscott, J. Hudson, R. Kepferle, P. O'Kita, A. Robertson, C. Stone, and R. Stevens. I am also deeply indebted to Bob Stevens for many hours of insightful discussion.

Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 9: Regional and Specific Deposits focuses on the processes, methodologies, principles, and approaches involved in the identification of regional and specific ore deposits. The selection first elaborates on the timing of mineralization in stratiform copper deposits, oolitic iron formations, and metalliferous deep-sea sediments. Discussions focus on marine distribution and nature of surface and near-surface deposits, structural setting and associated deposits, principal types of deep-sea metal-enriched sediments, chronological development of oolitic-inland-sea iron formation, and complementary sources and transport mechanisms. The text then tackles heavy-metal accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits. Topics include lithological associations, oxidation and supergene alteration of ores, temporal and tectonic setting, dissolved metal concentrations in large freshwater systems, and transport phases of heavy metals in river water. The publication examines strata-bound tin deposits, geology of the Pine Point lead-zinc district, and genesis of the Rammelsberg ore deposit near Goslar/Upper Harz in the Federal Republic of Germany. The selection is a valuable reference for researchers wanting to explore ore deposits.

Why another book about Ore Deposits? There are a number of factors which motivated us to write this text and which may provide an answer to this question. Firstly our colleagues are predominantly mining engineers and minerals processing technologists, which provides us with a different perspective of ore deposits from many academic geologists. Secondly we have found that most existing texts are either highly theoretical or merely descriptive: we have attempted to examine the practical implications of the geological setting and genetic models of particular ore deposit types. We have written the text primarily for undergraduates who are taking options in Economic Geology towards the end of a Degree Course in Geology. However, we hope that the text will also prove valuable to geologists working in the mining industry. The text is to a large extent based on a review of the existing literature up to the end of 1984. However, we have visited most of the mining districts cited in the text and have also corresponded extensively with geologists to extend our knowledge beyond the published literature. Nonetheless writing a text-book on Ore Deposits is a demanding task and it is inevitable that sins of both omission and commission have been committed. We would therefore welcome comments from readers which can be incorporated in future editions.
