Support of an AGU Chapman Conference: Fifth International Orogenic Lherzolite Conference: Shallow Mantle Composition and Dynamics, September 22-26, 2008, Mount Shasta Resort, CA

知识价值。本提案要求为2008年9月22日至26日在加利福尼亚州沙斯塔山的沙斯塔山度假胜地举行的美国地球物理联合会查普曼浅地幔组成和动力学会议（http://www.agu.org/meetings/chapman/2008/ccall/）的差旅和会议费用提供支持。这将是第五届国际造山热橄榄岩会议，以前的会议在兰佐（意大利北部，1990年）、隆达（西班牙，1995年）、菲内罗（意大利北部，1999年）和霍罗曼（日本，2002年）的橄榄岩地块附近举行。2008年是1977年查普曼地球部分融化会议召开31周年。这是本次会议的两个实地考察地点之一。这一地点是在本系列前一次会议上与会者的一致要求下选定的。更广泛的影响。这些会议的总目标是召集研究橄榄岩块和上地幔过程的专家召开一次实地会议，在那里可以分组讨论最近的结果和关键的露头。本次会议将纳入比以往更广泛的主题，并包括在岩石力学和低温蚀变过程有影响力的科学家在组委会，以确保这是一个成功的。主题将包括熔融过程，熔体运输，交代作用，局部和区域变形，板块边界的形成和性质，中深度地震的机制，以及低温蚀变的地球化学和物理过程。预计将有80至120名国际科学家出席，其中包括约20%的研究生和博士后研究人员。

Intellectual merit. This proposal requests support for travel and meeting costs for an American Geophysical Union Chapman Conference on Shallow Mantle Composition and Dynamics to be held September 22 to 26, 2008, at the Mount Shasta Resort, Mount Shasta, California (http://www.agu.org/meetings/chapman/2008/ccall/). This will be the fifth International Orogenic Lherzolite Conference, with previous conferences held near the peridotite massifs of Lanzo (N Italy, 1990), Ronda (Spain, 1995), Finero (N Italy, 1999), and Horoman (Japan, 2002). The year 2008 marks the 31st anniversary of the 1977 Chapman Conference on Partial Melting in the Earth?s Upper Mantle held in the Josephine peridotite, one of two field trip locales for the current meeting. This venue was selected as a result of unanimous request of the participants at the previous Conference in this series.Broader impacts. The overall objective of these meetings is to assemble specialists in studies of peridotite massifs and upper mantle processes for a field conference, where recent results and key outcrops can be discussed in a group setting. This conference will incorporate a broader range of topics than previously, and includes influential scientists in rock mechanics and low-temperature alteration processes in the organizing committee to ensure that this is a success. Topics to be covered will include melting processes, melt transport, metasomatism, localized and regional deformation, formation and nature of plate boundaries, mechanisms of intermediate depth earthquakes, and both geochemistry and physical processes of low temperature alteration. An attendance of between 80 and 120 international scientists is anticipated, including ~20% graduate students and post doctoral researchers.
