9614725 Leeman This grant provides $48,871 as partial support of the costs of upgrading the X-ray fluorescence spectrometer in the Geology and Geophysics Department at William Marsh Rice University. Specifically, the upgrade would include installation of a PC control system and associated software to replace the DEC PDP-11 system currently installed on their Rigaku XRF and two months salary for their current XRF technician who would train new users of the upgraded XRF. This upgrade would also include installation of a multi-layered crystal for analysis of light elements (i.e. B, F). Upgrade of the computer system will ensure the availability of a critical piece of analytical instrumentation for the analysis of major and trace elements in whole rock samples for studies in igneous and metamorphic petrology for Rice University and a host of other researchers in the Houston area. The enhanced capabilities to conduct analyses for light element concentrations (i.e Boron) within whole rock samples will immediately be utilized for research on fluid mobility during metamorphism. Continued petrologic studies of magmatic processes in a host of environments including volcanic island arcs, hot spots, intracontinental extensional regimes and metamorphic terranes will also take advantage of this upgrade. ***

9614725莱曼这笔赠款提供48,871美元，作为威廉·马什·赖斯大学地质和地球物理系X射线荧光光谱仪升级费用的部分支助。具体来说，升级将包括安装个人电脑控制系统和相关软件，以取代他们目前安装在Rigaku XRF上的DEC PDP-11系统，并为他们现有的XRF技术员支付两个月的工资，后者将培训升级后的XRF的新用户。这一升级还将包括安装用于分析轻元素(即B、F)的多层晶体。计算机系统的升级将确保为莱斯大学和休斯顿地区的许多其他研究人员提供一种关键的分析仪器，用于分析整个岩石样品中的主要和微量元素，用于火成岩和变质岩石学研究。对整个岩石样品中的轻元素浓度(即硼)进行分析的增强能力将立即被用于研究变质过程中的流体流动性。继续对包括火山岛弧、热点、陆内伸展制度和变质地体在内的一系列环境中的岩浆过程进行岩石学研究也将利用这次升级。***
