Infos

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.
