Scope
|
Fluids from subducting slabs trigger earthquakes and low frequency tremors, and return back as springs in fore-arc regions and produce magmas beneath volcanic arcs. Geofluids can be present everywhere and migrate in subduction zones and produce spatial and temporal variations in physical and chemical properties of materials. Thus the geofluids play an important role in the subduction-zone dynamics. This interdisciplinary session aims to promote the exchange of knowledge from cutting edge studies on geofluids and give perspectives to each participant. We continue to strongly encourage young researchers to participate in this session, because understanding geofluids can be essential in many geological and geophysical processes.

Notes
|
We would like to ask a favor to show the title and the authors of your presentation in your first slide. PC/Mac will be available on cite. Your own PC/Mac can be used. Please come to
the session in time for checking the file/computer communication. Your
active participation will be most welcome.
You can put your poster for a whole day, and the poster core time is set from 18:15 to 19:30.
