Book Description
This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the various tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks are genetically associated with a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and Carlin-type gold deposits. This fifth updated and expanded edition incorporates new data and references from world-class copper and gold deposits worldwide. It also includes the latest publications on the petrogenesis of high-K magmatism and related mineral deposits. Numerous new representative ore photographs of the mineral deposits described are also included in the new edition. As such, the book offers a valuable guide not only for academic petrologists working on alkaline rocks, but also for exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains.

Book Description
In June 1965, a small group of European economic geologists gathered in Heidelberg, Germany, at the invitation of Professor G. C. Amstutz and decided to establish the Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be called Mineralium Deposita. The first issue of the journal came out in May 1966, and has now matured to a leading journal in economic geology The first Biennial SGA Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London (United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002, th the SGA Council decided that its 8 Biennial Meeting in 2005 should be held in Beijing, China, making this the first Biennial Meeting to be convened outside - th rope. Significantly, 2005 also marks the 40 anniversary of the SGA. The decision to host this year’s premier meeting in Beijing reflects the Society’s successful transition from its traditional European focus to a truly global organization, with 24% of SGA members situated in North America, 13% in Australia and Oceania, and 5% in Asia. Over the last 27 years China has made dramatic progress towards political and economic reform, and opening the nation to the outside world. China’s rapid e- nomic development demands increasing amounts of minerals, fuels and materials, and this is currently a major driver for the global economic markets.

Book Description
In recent years, there has been increasing interest from geoscientists in potassic ig neous rocks. Academic geoscientists have been interested in their petrogenesis and their potential value in defining the tectonic setting of the terranes into which they were intruded, and exploration geoscientists have become increasingly interested in the association of these rocks with major epithermal gold and porphyry gold-copper deposits. Despite this current interest, there is no comprehensive textbook that deals with these aspects of potassic igneous rocks. This book redresses this situation by elucidating the characteristic features of potassic (high-K) igneous rocks, erecting a hierarchical scheme that allows interpre tation of their tectonic setting using whole-rock geochemistry, and investigating their associations with a variety of gold and copper-gold deposits, worldwide. About two thirds of the book is based on a PhD thesis by Dr Daniel Muller which was produced at the Key Centre for Strategic Mineral Deposits within the Department of Geology and Geophysics at The University of Western Australia under the supervision of Professor David Groves, the late Dr Nick Rock, Professor Eugen Stumpf!, Dr Wayne Taylor, and Dr Brendon Griffin. The remainder of the book has been compiled from the literature using the collective experience of the two authors. The book is dedi cated to the memory of Dr Rock who initiated the research project but died before its completion.

Book Description
Ross K. Dowling and David Newsome present an original, substantial and much-needed contribution to the field to further our understanding of geotourism in theory and practice. This Handbook defines, characterizes and explores the subject through a range of international perspectives and case studies, identifying geotourism as a rapidly emerging form of urban and regional sustainable development. With extensive case studies from North and South America, Europe, Asia, Australasia and Africa, this global Handbook examines and explains the relationship between geology and tourism. Thematically arranged sections cover the relationship of geology with tourism, sustainability and society, geotourism in urban areas, and interpretation and education strategies. The final two sections assess geotourism's impact through wide-ranging case studies of UNESCO global geoparks and geotourism in a range of countries. The eminent academics and practitioners demonstrate how geotourism is the future for engaging the public and protecting geosites, as well as emphasising the importance of sustainability. An essential resource for students and educators, this Handbook provides an international perspective for those interested in tourism, environmental geography, ecology and geology. Written with practitioners in mind, this book reveals how tourism professionals and geologists should each know about the nexus of their subjects.

Book Description
Interest in the study of early European cultures is growing. These cultures have left us objects made of gold, other metals and ceramics. The advent of metal detectors, coupled with improved analytical techniques, has increased the number of findings of such objects enormously. Gold was used for economic and ceremonial purposes and thus the gold objects are an important key to our understanding of the social and political structures, as well as the technological achievements, of Bronze and Iron Age European societies. A correct interpretation of the information provided by gold and other metal objects requires the cooperation of experts in the fields of social, materials and natural science. Detailed investigation of gold deposits in Europe have revealed the composition and genesis of the deposits as sources of the metal. In Prehistoric Gold in Europe, a group of leading European geoscientists, metallurgists and archaeologists discuss the techniques of gold mining and metallurgy, the socioeconomic importance of gold as coinage and a symbol of wealth and status, and as an indicator of religious habits, as well as a mirror of trade and cultural relations mirrored by the distribution and types of gold objects in prehistoric times.

Book Description
This book will broaden readers’ understanding of pegmatites in a special geodynamic setting, dealing with the emplacement of the Hagendorf-Pleystein Pegmatite Province (HPPP) in the Central European Variscides. This treatise illustrates the complex processes leading to the formation and partial destruction of the pegmatites, documenting the geochronological, chemical, mineralogical, geological and geomorphological / sedimentological data set. The book starts with a detailed account of the economic geology of the various pegmatites, explaining why these deposits are a major resource of ceramic raw materials. In its concluding section, a model of the pegmatite evolution in an ensialic orogen provides meaningful insights into the genetic aspects of pegmatite generation. The Late Paleozoic rare-element pegmatites of the HPPP, Oberpfalz-SE, Germany, rank among the largest concentrations in Europe. The biggest pegmatite of this mining district totals 4.4 million tons of ore (Hagendorf-South). The mining history of the HPPP is restricted to the 20th century, when local entrepreneurs started mining operations in search of ceramic raw materials, feldspar and quartz. Today the “Silbergrube Aplite” is still worked for feldspar. The traditional mining of pegmatitic and aplitic rocks in Central Europe, such as the Bohemian Massif, which is shared by Germany, the Czech Republic, Poland and Austria, has been focused on these industrial minerals. In addition to these major commodities, lithium was mined for a period of time. But even today many of these pegmatites of calc-alkaline affiliation have not lost their appeal to mineralogists and mineral enthusiasts for their wealth of minerals that contain P, Nb, Ta, Li, Be, B, U, Th, Sc, Ti and Sn. The most favorable crustal section to bring about pegmatitic rocks of this type, encompassing pegmatoids, metapegmatites, reactivated pseudopegmatites and pegmatites sensu stricto is the ensialic orogen, exemplified by the Variscan (Hercynian) Orogen, which geodynamically connects the Paleozoic pegmatite provinces in North America and Europe. The geological history of the HPPP, however, goes much further than the Carboniferous-Permian magmatic activity, when the last structural disturbances of the Variscan orogeny affected the NE-Bavarian Basement between 450 and 330 Ma. During this time mafic magmatic rocks together with calcareous and arenaceous sediments were converted into paragneisses, calcsilicate rocks, and amphibolites. It is the period of time when tectonic shortening led to over thrusting and when the emplacement of nappes and the architectural elements of the ensialic orogen began taking shape. During the Late Permian, the Mesozoic and the Cenozoic, the HPPP did not lie idle in geological terms; hypogene and supergene alteration continued and found its most recent expression in alluvial-fluvial “nigrine” placer deposits, which resulted from the unroofing of the pegmatites and aplites in the HPPP and can be used even outside HPPP as an ore guide to pegmatites.
