Outline of the sessions
S1: Dynamics of igneous processes [Joint session with the Volcanological Society of Japan]
| Outline | There have been a number of remarkable advances in our understanding of igneous processes and magma dynamics, including partial melting of the mantle and primary magma generation, magma differentiation, volcanic eruption, ore formation, contact metamorphism and metasomatism. Most of these studies are based on state-of-the-art Earth materials science, such as high-resolution geochemical analysis and small-scale observation of mantle xenoliths, volcanic and plutonic rocks, volcanic gases, and hot spring waters. The purpose of this special session is to discuss and promote the latest studies related to the dynamics of igneous processes. We welcome multidisciplinary contributions based on field observations, analyses of natural samples, high P/T experiments and theoretical modelling. |
| Convener(s) | Morihisa Hamada (mhamada[a]jamstec.go.jp), Shumpei Yoshimura, Yuto Sato |
S2: Water Rock Interaction
| Outline | Topic session “Water–Rock Interaction” involves multidisciplinary research for roles of “fluids” to the Earth Processes, related to metamorphic rocks, volcanic rocks, hydrothermal alteration, ore deposit, hydrothermal experiments, and transport phenomena of fluids. Research methods are also multidisciplinary research methods, such as field survey, experiment, numerical calculation and modeling, will be expected. This topic session also includes geological applications such as mineralogical study of radioactive decontamination, nuclear waste geological disposal and carbon dioxide capture and storage and geothermal energy. |
| Convener(s) | Noriyoshi Tsuchiya (noriyoshi.tsuchiya.e6[a]tohoku.ac.jp), Tetsuo Kawakami, Masaki Uno |
S3: Rheology and Material Transfer in Mantle and Crust
| Outline | The dynamics in the mantle and crust, which are the driving forces for the active Earth, have made significant progress in recent years through the integration of mineralogical and geophysical approaches. In this session, we welcome various presentations on field observations, rock microstructures, laboratory experiments, and reaction modeling related to rheology and material transfer in the mantle and crust. |
| Convener(s) | Ikuo Katayama (katayama[a]thiroshima-u.ac.jp), Katsuyoshi Michibayashi, Miki Tasaka, Tomoaki Kubo |
R1: Characterization and description of minerals (Joint Session with The Gemmological Society of Japan)
| Outline | This session focuses on mineral descriptions, characterization, and analytical methods of earth and planetary materials. Descriptions of occurrence, morphology, internal texture, crystal structure, chemistry, fluid inclusion, solid inclusion, crystal imperfections in minerals, studies on gem identification, and studies on development of analytical methods for mineral sciences are welcomed. (Joint session with the Gemological Society of Japan) |
| Convener(s) | Yasuyuki Banno (y-banno[a]aist.go.jp), Masanori Kurosawa, Yuji Kitawaki,Koichi Momma, Yohei Shirose |
R2: Crystal structure, crystal chemistry, physical properties of minerals, crystal growth and applied mineralogy
| Outline | This session covers structural descriptions of natural and synthetic minerals, their growth and dissolution mechanisms together with interesting physic-chemical properties. Presentations dealing with advanced analytical techniques for characterizing a variety of mineral structures and their fundamental properties are welcome. |
| Convener(s) | Kazuki Komatsu (kom[a]eqchem.s.u-tokyo.ac.jp), Mariko Nagashima, Fumiya Noritake |
R3: High-pressure science and deep Earth’s material
| Outline | It is significantly important to understand the wide range of mineral sciences in the Earth’s interior, because dynamics in the Earth’s interior must be closely related to not only the evolution of the Earth but also the environment near the Earth’ surface. The aim of this session will be to discuss the full range of physical and chemical properties of minerals on the basis of experimental and computational approaches. Targeted materials are not only minerals but also their analogous, amorphous materials and melt. |
| Convener(s) | Takaaki Kawazoe (kawazoe[a]hiroshima-u.ac.jp), Ryosuke Sinmyo, Takeshi Sakai, Masayuki Nishi, Takayuki Ishii |
R4: Mineral sciences of the Earth surface
| Outline | This session aims to discuss the latest advances in the mineralogical sciences of the Earth surface. The session will cover physical and chemical characteristics of micro- and nano-sized minerals, dissolution/precipitation of minerals, biomineralization processes, chemical phenomena at water-mineral interface, inorganic-organic interactions, and others. |
| Convener(s) | Jun Kawano (j-kawano[a]sci.hokudai.ac.jp), Tadashi Yokoyama, Hiroshi Sakuma, Satoko Motai |
R5: Extraterrestrial materials
| Outline |
We welcome contributions on mineralogical sciences of extraterrestrial materials such as presolar grains, cosmic dust, meteorites, lunar samples, and return samples. |
| Convener(s) | Megumi Matsumono (m_matsumoto[a]tohoku.ac.jp), Daiki Yamamoto, Toru Matsumoto |
R6: Plutonic rocks, volcanic rocks and subduction factory
| Outline | This session focuses on studies of plutonic and volcanic rocks. We expect lively discussions on magma genesis, magma emplacement and their relationship with tectonics, from the viewpoint of various disciplines such as petrology, mineralogy, geochemistry, dating, and geology. This session also welcomes studies on subduction factory that produces continental crust. The upcoming conference will take place in southwestern Japan, an area characterized by extensive distributions of Cretaceous to Paleogene igneous rocks. We particularly encourage submissions on topics related to these igneous rocks. |
| Convener(s) | Atsushi Kamei (kamei-a[a]riko.shimane-u.ac.jp), Tasuhiko Kawamoto, Takashi Yuguchi, Takashi Hoshide |
R7: Petrology, mineralogy and economic geology (Joint Session with The Society of Resource Geology)
| Outline |
This session accepts a wide range of scientific topics about petrology, mineralogy, economic geology, and geochemistry using terrestrial and planetary materials. We welcome various presentations and discussions about constituent materials of the Earth and other planets. |
| Convener(s) | Norikatsu Akizawa (akizawa[a]hiroshima-u.ac.jp), Takuya Echigo |
R8: Metamorphic rocks and tectonics
| Outline | We call for interdisciplinary contributions dealing with crustal and mantle dynamics at the plate convergent boundaries, including approaches from petrology, structural geology, geochronology, fluid inclusion studies, numerical modeling and isotope geochemistry. |
