US-Argentina Planning Visit to the Diamante Caldera Maipo Volcanic Complex; Mendoza, Argentina

这项美国-阿根廷奖将在宾夕法尼亚州立大学Maureen Feineman博士的指导下，支持一名初级科学家和一名研究生计划两次访问阿根廷。第一次访问将于2008年2月进行，第二次访问将于2009年2月进行。这些访问的主要目标是在宾夕法尼亚州立大学的研究人员和阿根廷的Servicio Geológico y Minero Argentino （SEGEMAR）之间开展长期合作。在这次合作中，宾夕法尼亚州立大学将为当地正在进行的Maipo火山复合体的实地工作提供详细的地球化学分析，该火山复合体位于安第斯山脉南部火山带的活跃部分。该小组将会见SEGEMAR的地质学家Patricia Sruoga博士，她在该地区拥有丰富的实地经验，是迄今为止对Maipo进行的最完整的地球化学评估的第一作者。在这两次访问期间，研究人员将熟悉该地区的地理和地质，为初步的地球化学工作收集样本，并为两个机构之间的未来合作制定战略。研究人员计划在岩石学和地球化学上提出合作建议。这次访问将包括一位非常有才华的早期职业PI和一名研究生。它有可能产生一系列关于迈坡火山复合体下岩浆补给、储存和演化过程的未来研究，并将进一步了解是什么引发了一个相对平静的火山历史中偶尔的剧烈喷发。

This U.S- Argentina award will support one junior scientist and one graduate student, under the direction of Dr. Maureen Feineman of Penn State University, on two planning visits to Argentina. The first visit will take place in February 2008 and the second in February 2009. The primary goal of these visits is to initiate a long-term collaboration between researchers at Penn State University and Servicio Geológico y Minero Argentino (SEGEMAR) in Argentina. In this collaboration, Penn State will provide detailed geochemical analysis to locally-based ongoing field work at Maipo Volcanic Complex which is situated in an active part of the Southern Volcanic Zone in the Andes. The team will meet with Dr. Patricia Sruoga, a geologist with SEGEMAR who has extensive field experience in this region and is the first author of the of the most complete geochemical assessment of Maipo to date. During these two visits, the researchers will familiarize themselves with the geography and geology of the area, collect samples for preliminary geochemical work, and develop a strategy for future collaborations between the two institutions. The investigators plan to develop a collaborative proposal in Petrology and Geochemistry. The visit will involve a very-talented early-career PI and one graduate student. It has the potential to generate a series of future studies regarding the processes of magma recharge, storage, and evolution beneath Maipo Volcanic Complex and will further our understanding of what triggers the occasional violent eruption in a volcano that has a relatively quiescent volcanic history.
