9810089 Ague这笔拨款为耶鲁大学地质与地球物理系x射线衍射仪（XRD）和电子显微探针（EMP）实验室运行所需的仪器和计算机升级提供部分支持。具体的升级包括：(1)用现代化的基于PC的系统取代过时的XRD计算机和软件。(2)升级电磁脉冲上的能量色散探测器，以提高峰值分辨率，并能够检测轻元素（B、C、N、O、F）。(3)将电磁脉冲上用于图像采集/处理、x射线测绘和能量色散光谱采集和处理的过时计算机和软件替换为基于现代pc机的系统。(4)更换EMP实验室陈旧的涂炭机。x射线衍射仪（XRD）和电磁脉冲仪（EMP）是该系教职员工、学生、博士后、研究分支机构和访问学者的宝贵工具，涉及的研究范围广泛，包括：(1)野外变质和火成岩岩石学，(2)实验岩石学/地球化学，(3)沉积和风化过程地球化学，(4)经济地质学，(5)构造地质学和构造学，(6)古生物学，(7)考古冶金学，(8)生物矿化。＊＊＊

9810089 Ague This grant provides partial support for upgrading instrumentation and computers required for operation of the X-ray diffractometer (XRD) and electron microprobe (EMP) laboratories in the Department of Geology and Geophysics, Yale University. Specific upgrades include: (1) Replace obsolete XRD computer and software with modern PC- based system. (2) Upgrade the energy-dispersive detector on the EMP in order to improve peak resolution and enable detection of light elements (B, C, N, O, F). (3) Replace obsolete computer and software on EMP used for image acquisition/processing, X-ray mapping, and energy- dispersive spectrum acquisition and processing with modern PC-based system. (4) Replace obsolete carbon coater in EMP laboratory. The XRD and EMP are invaluable Departmental workhorses for faculty, students, post-docs, research affiliates, and visiting scholars involved in a broad spectrum of research, including: (1) Field-based metamorphic and igneous petrology, (2) Experimental petrology/geochemistry, (3) Geochemistry of sedimentary and weathering processes, (4) Economic geology, (5) Structural geology and tectonics, (6) paleontology, (7) Archaeometallurgy, and (8) Biomineralization. ***
