スコープ 和文
Major orogenic belts on earth are formed by multi-dynamic processes such as subduction and collision. The resulted belts extend for hundreds of kilometers and the lithological or tectonic units preserve records of the evolutionary events. Investigation of such orogenic belts on a regional scale, rocks and minerals on a macro- and micro-scale, and understanding how, when and under what conditions the rocks and minerals formed allow earth scientists to elucidate geological events that occurred in the earth's interior and/or near the surface. Investigation of stress-strain regimes of rocks and minerals envisage deformation at plate-scale. Similarly, investigating crystallization/recrystallization of minerals from magma or due to metamorphic reactions, we can interpret the past events of the earth's history.  Detailed geochemical analysis of bulk rocks and minerals enables us to estimate the water-rock interaction ratios and the role of fluid in the formation of minerals and rocks. Finally, geochronological investigations of specific minerals (such as zircon, garnet, rutile, apatite etc.) give information regarding the time-scale of crustal growth or metamorphic events. 
The proposed international session in the JpGU 2024 aims at bringing earth scientists from Japan and overseas to present their research related to the processes of subduction, collision, and metamorphism of crustal rocks, formation of the oceanic/continental arcs, and accretion/ tectonic erosion of material along subduction boundaries. 
Topics such as processes in subduction zones, accretion of volcaniclastic or terrigenous sediments along the subduction/collision boundaries, deformation and metamorphism of subducted crust, recycling of material, and geochemical and geophysical methodologies to unravel the geodynamic history preserved in various orogenic belts will be focus of the session. Exchange of ideas among geoscientists related to the theme of the session is most welcome.
