SUMMARY:Atle Rotevatn
DESCRIPTION:Deformation and slip localization in porous volcaniclastic rocks: tuff adventures in eastern Taiwan \nAtle Rotevatn \nTaiwan features some of the highest uplift rates\, and highest erosion rates in the world. With that comes growing mountains\, rapidly incising river gorges\, highly active surface processes and related geohazads\, all of which makes this a very interesting place to any geoscientist. Eastern Taiwan also features an accreted island arc complex\, where volcanism that occurred approximately 5 million years ago has produced an absolutely awesome succession of volcaniclastic deposits knowns as the Shihtiping Tuffs. This succession has been deformed at relatively shallow burial depth during ongoing plate convergence\,  and between 2015 and 2017 I had the pleasure of spending three field seasons with students from UiB and colleagues from the University of Bordeaux and the National Taiwan University in that area. In the years that have followed\, more people have become involved\, and in this talk I will talk about the deformation features we see in the Shihtiping Tuffs\, and what they can teach us about deformation mechanisms and controls on slip localization in such rocks.
