[H-CG27] Turbidity current: from triggers for the generation to the depositional and morphologic al processes

Mon. May 27, 2019 10:45 AM - 12:15 PM 301B (3F)

convener:Miwa Yokokawa(Osaka Institute of Technology), Hajime Naruse(Department of Geology and Mineralogy, Graduate School of Science, Kyoto University), Norihiro Izumi(Faculty of Engineering, Hokkaido University), Ken Ikehara(Institute of Geology and Geoinformation, National Institute of Advanced Industrial Science and Technology), Chairperson:Hajime Naruse(Kyoto University), Ken Ikehara(AIST)

Recent developments of field observation, physical and numerical experiments, and mathematical analysis have brought us a better understanding of the dynamics of turbidity currents and relevant morphology and bedforms. Applying new findings to rock records, more profound understanding of turbidites have been achieved. It has been found that different triggers and/or sources generate distinctive features of turbidity currents, resulting in various appearances of rock records and morphology. The integration of such new knowledge on turbidity currents is important not only from scientific but also practical points of view, such as assessments of natural hazards, and exploration of resources. This international session welcomes all kinds of approaches for the turbidity currents such as field observation, physical and numerical experiments, mathematical analysis, and studies from rock records.
