  • Description

    Many Neogene hydrothermal ore deposits have been formed on and near the Japanese islands from the middle Miocene to the present day and today many subaerial and submarine active geothermal systems are active.

    This book summarizes the geochemical and tectonic features, and the evolution of various types of ore deposits and current island arc and backarc hydrothermal systems in Japan starting with the Mesozoic.

    Reviews

    "I recommend this work for all researchers, professionals and students, who will find all the necessary up to date information on island-arc related mineralization here. This is also an excellent bibliographic resource with over 1,000 references." -MINERALIUM DEPOSITA, VOL 39, 2005 @from:M.D. Hannington @qu:...is recommended as a resource for the advanced researcher in the geochemistry of epithermal vein deposits and submarine hydrothermal systems, both modern and ancient, and as an introduction to these systems for students at the senior undergraduate level. @source:Economic Geology
