Under the general theme "Mineral Exploration and Sustainable Development" the meeting brought together economic geologists from academia, government, and industry to discuss current issues regarding exploration for mineral deposits and their sustainable development by the minerals industry. In these proceedings more than 300 papers are published. They are grouped thematically as follows: -Plenary lectures -Sustainable development and geoenvironmental impact models -Supergene metallogenic processes -Seafloor hydrothermal systems -Porphyries/granites and the magmatic-hydrothermal transition -Epithermal systems -Ore forming processes associated with mafic and ultramafic rocks -Basin evolution and ore forming processes -Orogenic hydrothermal systems -Organic matter and mineral deposits -Industrial minerals -Special session: FeOx-Cu-Au, VMS, and orogenic gold deposits in light of the tectonic evolution of the Fennoscandian Shield -SEG Symposium: Exploring for Tethyan ores: Development from historic roots
