Ore deposits consisting of supracrustal concentrated valuable elements and minerals result from the earth dynamics including magmatism, hydrothermal activity, metamorphism, and weathering process. Also, the formation of ore deposits is closely associated with global environmental changes and biological evolution in the Earth's history. Involvement of different academic fields in earth sciences including geology, petrology, geochemistry, mineralogy and microbiology is required to elucidate the genesis of ore deposits. The field of resource geology is essential not only for efficient exploration and development of ore deposits but also for better understanding and assessment of hazardous elements that may be caused by resource development. This session widely covers various topics of field investigation and observation, laboratory experiments, theoretical calculation, development of analytical methods and others related to the supracrustal migration and concentration of elements.
