Acquisition of an Automated Powder X-Ray Diffractometer

9318346 Haymon该奖学金提供了购买粉末x射线衍射仪系统所需资金的一半，该系统将在加州大学圣巴巴拉分校地质科学系安装和运行。大学承诺提供收购所需的剩余资金。新的x射线衍射仪将取代一台已有32年历史的仪器，该仪器不再能够提供该机构众多研究和教学项目所需的数据。将使用新仪器的研究项目包括：(1)东太平洋隆起脊热液喷口矿化时间序列研究；(2)沉积盆地化学成岩作用和孔隙流体运动研究；(3)新生代古海洋/古气候演化的海相沉积记录；(4)上升流带新生代化学波动的珊瑚记录；(5)变质地体的区域热气压研究；(6)硅酸盐熔融运输性质研究。＊＊＊

9318346 Haymon This award provides one-half of the funding required to purchase a powder X-ray diffractometer system to be installed and operated in the Department of Geological Sciences at the University of California at Santa Barbara. The University is committed to providing the remaining funds necessary for the acquisition. The new X-ray diffractometer will replace a 32-year old instrument no longer capable of providing the type of data required by numerous research and teaching programs at the institution. Among the research projects that will use the new instrumentation: (1) A time- series study of mineralization at hydrothermal vents on the East Pacific Rise crest, (2) Studies of chemical diagenesis and pore fluid movement in sedimentary basins, (3) Marine sediment records of Cenozoic paleoceanographic/paleoclimatic evolution, (4) Coral records of Cenozoic chemical fluctuations in upwelling zones, (5) Regional thermobarometric studies of metamorphic terranes, and (6) Studies of silicate melt-transport properties. ***
