VOLCANO: IAVCEI session I.4 “Arc evolution: space, time, morphology, and longevity of volcanic arcs”

[Sean Peters <speter24@xxxxxxx>]

Dear Colleagues, 

Happy New Year and all the best for 2017. 

We would like to invite you to submit an abstract to our IAVCEI session I.4 “Arc evolution: space, time, morphology, and longevity of volcanic arcs” (http://iavcei2017.org/ses_I4.html). 

We are looking forward to receiving your contributions (deadline for abstract submission is March 17, 2017) and meeting you in Portland in August 14-18!! Please submit your abstracts following the instructions available here: http://iavcei2017.org/

Arc evolution: space, time, morphology, and longevity of volcanic arcs

Arc settings are foundries in which heat, mass, and fluid transfer processes contribute to constructing the continental crust, feeding volcanic eruptions, and maintaining a hydrosphere and atmosphere on Earth. Volcanic edifices in arcs span a wide range in morphology, volume, and eruptive longevity, reflecting temporal and spatial variations in melt extraction processes within the Earth’s lithosphere. To date, constraints on the production and eruption of magmas, the modulation of volcanism by tectonic and landscape evolutionary processes, and the links amongst the dynamics of the mantle, crust and surface do not fully explain the factors controlling the eruptive volume, spatial, temporal and compositional variability of eruptions at a given volcano or at an arc scale. 

This session will explore magmatic, tectonic and surface processes associated with dynamics of magma transport in controlling the spacing, volume, and longevity of volcanic edifices in arcs. This session will emphasize interactions between scientists interested in identifying mantle-crust-surface processes controlling the architecture and tempos of arc volcanism with implications for volcanic hazards. 

Studies investigating along-arc variations and comparing different arc systems, through integrative approaches, are encouraged. This session is aimed at initiating “arc databases” linking magmatic, tectonic, and surface processes over a range of spatial and temporal scale.
