0111183RutherfordThis award will supply funding which will be used along with cost-sharing funds from Brown University to purchase a new Electron Microprobe. This instrument, with its state of the art analytical and surface imaging capability, will be an analytical centerpiece for a large number of research projects carried out by faculty, post-docs, graduate students, and undergraduates at Brown and as well as from the nearby University of Rhode Island. Research projects which will make use of the Microprobe include the following: (1) studies of minerals and glasses in volcanic rocks collected from recently active centers around the world directed at determining the nature and timing of processes involved in volcanic eruptions. (2) basic studies of diffusion and reaction kinetics in both naturally occurring and synthetic geological materials, (3) studies of deformation of geological materials in both the brittle and ductile regimes with application to understanding earthquakes fracturing processes in rocks, (4) studies of plate tectonic processes as revealed in the ages of minerals and rocks, and (5) studies of rocks and volcanic processes as they occur on other planetary bodies such as the Earth's moon and Mars. This research involves approximately ten faculty at Brown, three at nearby URI, and as many as twenty graduate students, five post-doctoral fellows, and five to ten undergraduates each year. ***

0111183卢瑟福该奖项将提供资金，将用于沿着与成本分摊基金从布朗大学购买一个新的电子探针。 该仪器具有最先进的分析和表面成像能力，将成为布朗大学和附近的罗得岛大学的教师、博士后、研究生和本科生开展的大量研究项目的分析中心。 利用微探针的研究项目包括：（1）研究从世界各地最近活跃的火山中心收集的火山岩中的矿物和玻璃，旨在确定火山爆发过程的性质和时间。(2)天然和合成地质材料中扩散和反应动力学的基础研究，（3）脆性和韧性体系中地质材料变形的研究及其在理解岩石中地震破裂过程中的应用，（4）矿物和岩石年龄揭示的板块构造过程的研究，（5）研究岩石和火山过程，因为它们发生在其他行星上，如地球的月球和火星。这项研究涉及布朗大学的大约10名教师，附近的URI的3名教师，以及每年多达20名研究生，5名博士后研究员和5至10名本科生。 ***
