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 Leeman这笔赠款提供了48,871美元，以部分支持升级威廉·沼泽莱斯大学地质和地球物理学的X射线荧光光谱仪的成本。 具体而言，升级将包括安装PC控制系统和相关软件，以替换当前在其Rigaku XRF上安装的DEC PDP-11系统，以及目前的XRF技术人员的薪水两个月，该技术人员将培训已升级的XRF的新用户。 此升级还将包括安装多层晶体，用于分析光元素（即B，F）。 计算机系统的升级将确保在整个岩石样品中的主要和痕量元素的分析，以确保对赖斯大学的火成岩和变质岩学研究以及休斯顿地区的其他许多研究人员进行研究。 在整个岩石样品中进行光元素浓度（即硼）进行分析的增强能力将立即用于变质过程中的流体迁移率。 在许多环境中，包括火山岛弧，热点，室内伸展机制和变质台等环境中的岩浆过程的继续研究也将利用这一升级。 ***
