Acquisition of a new Electron Microprobe

0111183卢瑟福这项奖励将提供资金，这些资金将与布朗大学的成本分摊资金一起用于购买新的电子显微探头。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罗德岛大学的教职员工、博士后、研究生和本科生开展的大量研究项目的分析中心。将利用微探测器的研究项目包括：(1)从世界各地最近的活动中心收集的火山岩中矿物和玻璃的研究，旨在确定火山喷发过程的性质和时间。(2)自然地质材料和合成地质材料中扩散和反应动力学的基础研究；(3)脆性和韧性地质材料的变形研究，用于了解岩石中的地震破裂过程；(4)矿物和岩石年龄揭示的板块构造过程的研究；以及(5)在地球的月球和火星等其他行星体上发生的岩石和火山过程的研究。这项研究涉及布朗大学的大约10名教员，附近的URI大学的3名教员，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。***

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. ***
