Cascade21: A workshop to catalyze and synthesize understanding of the role of magmatism in an archetype continental arc

喀斯喀特山脉的火山对太平洋西北地区的人口构成重大危险。对于地质学家来说，这些火山也发挥了重要作用，他们试图了解俯冲作用--一个构造板块被推到另一个构造板块之下--如何产生岩浆和火山活动。为了促进对喀斯喀特山脉火山活动和相关过程的更深入了解，我们计划举办Cascade 22研讨会，该研讨会综合了岩浆活动在俯冲带中的重要作用的最新数据和发现，特别关注卡斯卡迪亚俯冲带。会议计划于2022年夏季在俄勒冈州的弯曲市举行，为期五天，将包括早期职业科学家日和实地考察。会议将为学生和早期职业研究人员提供一系列培训，指导和研究机会。研讨会将从典型的级联弧系统的角度对俯冲带岩浆活动的关键方面进行多学科检查，从深地幔到地表，并将作为一个论坛，综合广泛的地球物理，地球化学，火山学，地质学，文化和其他观测，以了解岩浆过程在俯冲带系统中所起的复杂作用。从某种意义上说，这次会议将重演1968年安山岩会议，著名的组织者是亚历山大·麦克伯尼和其他人（麦克伯尼，1969年），地点是俄勒冈州的尤金和弯曲。然而，我们也将强调过去五十年的科学和文化变革，并集中注意力在未来的挑战。会议还设计了一个现场部分，弯曲提供了无与伦比的访问火山地区，是一个很好的出发点，为进一步探索喀斯喀特弧和其他附近地区。该研讨会将是小型到中型（约80人），为期五天-第一次侧重于早期职业参与者，一天专门用于中期会议实地考察。将有三天的口头和海报会议。这些会议将围绕需要采取多学科办法并直接促进综合的问题进行设计，而不是集中讨论个别研究学科。主题发言人将被分配从不同学科的角度提供投入，并将有足够的时间进行小组讨论和简短的演讲，以及单独的海报会议。每个主题都将成为后续期刊特刊综合论文的基础。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The volcanoes of the Cascade Range represent significant hazards to the population of the Pacific Northwest region. These same volcanoes have also played an important role for geologists that seek to understand how subduction – the pushing of one tectonic plate beneath another – produces magma and volcanic activity. To promote greater understanding of volcanism and related processes in the Cascade Range, we plan to hold Cascade22, a workshop synthesizing recent data and discoveries of the important role of magmatism in subduction zones, with a specific focus on the Cascadia Subduction zone. The conference is planned to be held over five days in summer 2022, in the city of Bend, Oregon, and will include an early career scientist day and a field trip. The conference will provide students and early career researchers with a range of training, mentoring and research opportunities.The workshop will be a multidisciplinary examination of critical aspects of magmatism in subduction zones from the perspective of the canonical Cascade Arc system, from the deep mantle to the surface, and will serve as a forum for synthesizing a broad range of geophysical, geochemical, volcanological, geological, cultural and other observations relative to understanding the complex roles played by magmatic processes in subduction zone systems. In some sense the conference will reprise the 1968 Andesite conference, famously organized by Alexander McBirney and others (McBirney, 1969) in Eugene and Bend, Oregon. However, we will also highlight the scientific and cultural changes of the last five decades, as well as focusing attention on challenges that lie ahead. The conference is also designed to have a field component, and Bend provides unsurpassed access to volcanic areas, and is an excellent stepping off point for further exploration of the Cascade arc and other nearby regions. The workshop will be small to medium-sized (~80 people) and be held over five days – with the first being focused on early career attendees and one day dedicated to a mid-conference field trip. There will be three days of oral and poster sessions. Rather than focus sessions on individual research disciplines, the sessions will be designed around issues that require a multidisciplinary approach and that directly promote synthesis. Keynote speakers will be assigned to provide input from different disciplinary perspectives, and there will be ample time for group discussions and shorter presentations, as well as separate poster sessions. Each of these topics will then become the basis for a synthesis paper in subsequent journal special issues.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
