Support for Proposed 'State of the Arc' (SOTA) Conference: Energy and Mass Fluxes in Volcanic Arcs

根据这项裁决，国际和平研究所将召开旨在了解俯冲区物理化学过程的一系列弧形(SOTA)会议中的第三次会议。这次会议将以火山弧区的能量和质量通量为主题。会议将于2003年8月在Timberline Lodge(Mt.胡德)。莱斯大学将担任牵头机构，会议将由波特兰州立大学在当地主办。这次会议将汇集大约84名国际研究人员，他们的工作与会议主题有关。具体的重点领域将包括：(1)俯冲带的热结构，(2)这种结构对从俯冲板块释放挥发物和可能的熔体的影响，(3)这种结构对地幔和地壳不同层次岩浆的产生和分异的影响，(4)对储存和释放这些岩浆及其相关流体的储集层的地质、岩石学、地球化学和地球物理约束，以及(5)弧形火山在不同空间和时间尺度上的热量和质量传输过程和速率，以及这些如何影响火山的演化和行为。会议将包括一系列会议前、会议中和会议后的实地考察，以了解喀斯喀德省(Mt.圣海伦斯山胡德和俄勒冈州中部)。这些旅行将把实地地质学的各个方面与会议主题结合起来，并使不同类型的弧火山作用形成对比。

Under this award, the PI will convene the third in a series of State of the Arc (SOTA) conferences aimed at understanding physical-chemical processes operating at subduction zones. The conference will have as its theme, Energy and Mass Fluxes in Volcanic Arcs. The meeting will be held in August 2003 at Timberline Lodge (Mt. Hood). Rice University will act as the lead institution, and the conference will be hosted locally by Portland State University. The meeting will bring together approximately 84 international researchers whose work bears on the conference theme. Specific focus areas will include: (1) the thermal structure of subduction zones, (2) the influence of this structure on release of volatiles and possibly melts from subducted slabs, (3) influence of this structure on the production and differentiation of magmas at various levels in the mantle and crust, (4) geologic, petrologic, geochemical, and geophysical constraints on the reservoirs that store and release those magmas and their associated fluids, and (5) heat and mass transfer processes and rates in arc volcanoes at different spatial and temporal scales, and how these influence volcano evolution and behavior. The conference will include a series of pre-, mid-, and post-conference field trips to view important aspects of arc volcanism as exposed in the Cascades province (Mt. St. Helens, Mt. Hood, and central Oregon). These trips will integrate aspects of field geology with the conference themes and allow contrast between different styles of arc volcanism.
