Distribution and Morphology of Arc Volcanoes

9316350卡尔拟议工作的目的是发现新的物理约束，这将导致更好地了解弧火山。 我们提出两个项目。 首先是量化弧火山活动的空间分布，特别强调测量火山的大小。 第二个项目是研究弧火山的形态，以确定它们是否与化学或其他物理参数有关。 拟议工作的意义在于，火山作用是收敛边缘管理过程的可观察到的地表结果。 弧火山作用存在着高度复杂的地球化学模型，人们曾多次尝试将地球化学参数与构造和火山学特征联系起来。 我们建议量化火山分布和形态，主要集中在中美洲。 然后，我们将确定新的物理数据和现有的地球化学数据之间存在什么样的相关性，并使用结果来尝试消除一些熔融生成和迁移的几个竞争模型。

9316350 Carr The purpose of the proposed work is to discover new physical constraints that will lead to a better understanding of arc volcanoes. We propose two projects. The first is to quantify the spatial distribution of arc volcanism, with special emphasis on measuring the sizes of volcanoes. The second project is to examine the morphologies of arc volcanoes to determine if they can be related to chemical or other physical parameters. The significance of the proposed work is that volcanism is the observable surface result of the managing processes at convergent margins. Highly sophisticated geochemical models exist for arc volcanism and several attempts have been made to link geochemical parameters to tectonic and volcanological features. We propose to quantify volcano distribution and morphology, focussing for the most part on Central America. We will then determine what correlations exist between the new physical data and existing geochemical data and use the results to try to eliminate some of the several competing models of melt generation and migration.
