Book Description
This special volume stems from a symposium 'Granitic Systems - State of the Art and Future Avenues' that was held at the Department of Geology, University of Helsinki to mark the retirement of Professor Ilmari Haapala. The twenty articles in the volume cover a wide range of granite-related topics and focus on three general themes: tectonics and source regions, petrologic processes, and fractionated granites and pegmatites. Both original papers and reviews are included, and the volume will be acknowledged by anyone with a background in Earth Sciences ad a flavor for granitoid rocks. * Comprehensive account of the current status of granite-oriented research * Topics ranging from mineralogy, petrology, and geochemistry to tectonics and crustal evolution

Book Description
Rapakivi Granites and Related Rocks tells the story of Rapakivi granites, which are a group of granitic rocks characterized by specific texture (presence of plagioclase-mantled ovoidal to subhedral alkali feldspar megacrysts, two generations of quartz and feldspars) and A-type geochemical composition. Well-known representatives are the Proterozoic rapakivi granites that are found as anorogenic or post-orogenic batholith- to stock-sized intrusive complexes in the Precambrian cratons of Ukraine, Fennoscandia, South Greenland, Canada, United States, Brazil, Venezuela, and Siberia. The current knowledge of the rapakivi granites is largely based on the achievements of three International Geological Correlation Programme projects: IGCP-315 (Rapakivi Granites and Related Rocks) in in 1991-1996, IGCP-426 (Granite Systems and Proterozoic Lithospheric Processes) in 1998-2002, and IGCP-510 (A-type Granites and Related Rocks Through Time) in 2005-2009. After these projects, the research has continued actively utilizing enhanced geochemical methods, in situ geochemistry in particular. Rapakivi Granites and Related Rocks includes this research as well as abundant new geochemical and isotopic data combined with deeper understanding of geotectonic processes now allow more detailed tectonic and petrological modelling of the rapakivi granite magmatism and associated ore mineralization.

Book Description
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.

Book Description
Medical Geology is a rapidly growing field concerned with the relationship between natural geological factors and human and animal health, as well as with improving our understanding of the influence of environmental factors on the geographical distribution of health problems. This book brings together the work of geoscientists and medical/public health researchers, which addresses health problems caused, or exacerbated by geological materials (rocks, minerals, atmospheric dust and water) and processes (including volcanic eruptions and earthquakes. Among the environmental health problems discussed in this book are: exposure to toxic levels of trace essential and non-essential elements such as arsenic and mercury; trace element deficiencies; exposure to natural dusts and to radioactivity; naturally occurring organic compounds in drinking water; volcanic emissions, etc. The text also deals with the many health benefits of geologic materials and processes. This wide-ranging volume covers issues in medical geology all over the world with each author covering their respective region. It provides examples from different continents as well as a state-of-the-art review of the latest developments in the discipline. The authors are all recognized geoscientific and medical experts working in the field. The book is written for a wide variety of specialists from geologists, geochemists, pathologists and medical doctors to veterinarians and biologists.

Book Description
This book focuses on the geological evolution of Southwest (SW) Gondwana and presents state-of-the-art insights into its evolution. It addresses the diachronic assembly of continental fragments derived from the break-up of the Rodinia supercontinent later amalgamated to build SW Gondwana during the Neoproterozoic–Cambrian transition, which on a global scale includes parts of present-day South America, Africa and Madagascar. The book presents 24 state-of-the-art reviews including the most crucial controversies. Most experienced scientists about the geology of SW Gondwana from Europe, Africa, South America and Australia present contributions on key areas addressing the interactions between the main cratons and fold belts on both sides of the South Atlantic Ocean. Chapters related to the geology of the major Archean- Paleoproterozoic cratons and Neoproterozoic Brasiliano/Pan-African fold belts enable readers to gain an in-depth understanding of the tectonometamorphic and magmatic evolution of SW Gondwana. The book covers a wide range of issues including metallogenetic, sedimentary, paleobiological and paleoclimatic processes and allows a deep insight into this key period of the Earth’s evolution.

Book Description
The Guiana Shield is an area of special importance, especially to those concerned with Precambrian geology because it provides a perspective on a part of Earth history not well represented elsewhere. For economic geologists, its mineral resource potential is just beginning to be understood. This overview of current knowledge will greatly help geologists already working in the area, draw attention to the need for mineral exploration research, and encourage the inclusion of the Shield in future Precambrian studies.
