This volume brings together a collection of papers that summarize current ideas and recent progress in the study of granite-related mineralization systems. They provide a combination of field, experimental and theoretical studies. Papers are grouped according to the main granite-related ore systems: granite-pegmatite, skarn and greisen-veins, porphyry, orogenic gold, intrusion-related, epithermal and porphyry-related gold and base metal, iron oxide-copper-gold (IOCG), and special case studies. The studies provide a broad spread in terms of both space and time, highlighting granite-related ore deposits from Europe (Russia, Sweden, Croatia and Turkey), the Middle East (Iran), Asia (Japan and China) and South America (Brazil and Argentina) and spanning rocks from Palaeoproterozoic to Miocene in age.
This volume presents a selection of papers resulting from the INTAS Project 93-1783 "Ore-bearing granites of Eurasia: Anatomy and mag-matic-hydrothermal mechanisms of ore deposition" (INTAS = International Association for the Promotion of Cooperation with Scientists from the New Independent States of the Former Soviet Union). It is the second monograph from this project, after our 1996 publication of "Granite-Related Ore Deposits of Central Kazakhstan and Adjacent Areas" (Shatov et al, 1996). The monograph contains 19 contributions of which 14 papers provide regional overviews on a number of important granite and ore provinces (northern and central Kazakhstan, Urals, Mongolia, Caucasus, Siberia, Yakutia, Pamirs). Five other papers are on general aspects of granite magmatism (geophysics, metasomatic zoning, volatile composition, petrogenetic tracing). An introductory paper compiles hitherto unavailable data on ore resources, mining production, uses, and applications for more than one hundred major granite-related rare-metal ore deposits of the former Soviet Union. Figure 1 illustrates the location of those areas treated in this volume. There are a number of significant rare-metal granite areas which are not covered by review papers. These gaps result from the fact that our INTAS project cooperation could only reach a limited number of FSU research groups, and that several papers submitted could not be accepted for publication. This volume provides a first and hitherto unavailable overview of the geology and metallogeny of major granite-related rare-metal deposits of Russia and adjacent countries. The papers may be used as astarting point for those interested in a particular area. The publication will be useful to the mineral exploration and mining community, and to all geoscientists interested in granite-related metallogeny.
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.
Volume 50 of Reviews in Mineralogy and Geochemistry treats Beryllium and its cosmogenic isotopes. This volume includes an overview of Be studies in the earth sciences and a systematic classification of Be minerals based on their crystal structure. It treats the analysis of these minerals by the secondary ion mass spectroscopy as well as experimental studies of systems involving Be. Moreover, this volume reviews the behavior of Be in the Solar System, with an emphasis on meteorites, the Moon and Mars, and the implications of this behavior for the evolution of the solar system. It gives an overview of the terrestrial geochemistry of Be and discusses the contamination of the environment by this anthropogenic toxin. It reports use of the longer lived Be-10 to assess erosion rates and other surficial processes and how this isotope can yield independent temporal records of geomagnetic field variations for comparison with records obtained by measuring natural remnant magnetization, be a chemical tracer for processes in convergent margins, and can date events in Cenozoic tectonics. It reviews applications of the shorter lived isotope Be-7 in environmental studies as well. Residual phases include acidic plutonic and volcanic rocks, whose geochemistry and evolution are covered, while granitic pegmatites, which are well-known for their remarkable, if localized, Be enrichments and a wide variety of Be mineral assemblages, are reviewed. Not all Be concentrations have obvious magmatic affinities; for example, one class of emerald deposits results from Be being introduced by heated brines. Pelitic rocks are an important reservoir of Be in the Earth's crust and their metamorphism plays a critical role in recycling of Be in subduction zones, eventually, anatectic processes complete the cycle, providing a source of Be for granitic rocks.
