9413693 Rumble This award provides one-half the funding for the acquisition of the components needed to build an ultra- violet laser microprobe for the analysis of oxygen isotope ratios in silicate and oxide minerals. The laser microprobe will be designed, built, installed, and operated in the Geophysical Laboratory of the Carnegie Institution of Washington. The Carnegie Institution of Washington is committed to providing the remaining funds necessary to complete the project. The development of the laser microprobe system for in situ microanalysis of oxygen isotope concentrations is expected to make a large impact in the interpretation of stable isotope variations in geological systems by allowing the measurement of isotopic variations to be made with a spatial resolution of several micrometers, comparable to the scale on which mineral samples preserve the isotopic zoning inherited during growth. ***

9413693隆隆声奖励该奖项提供了一半的资金，用于获取构建超紫罗兰色激光微探针所需的组件，以分析硅酸盐和氧化物矿物质中的氧同位素比。激光微型探针将在华盛顿卡内基机构的地球物理实验室设计，建造，安装和操作。华盛顿卡内基学会致力于提供完成该项目所需的剩余资金。用于原位微分析的激光微型探针系统的开发预计，预计通过允许同位素变化的测量，可以用几微米的空间分辨率与几个刻度相比，在矿物质样品中，在矿物量表上可以使同位素变化对同位素变化进行测量，从而对地质系统中稳定的同位素变化产生很大的影响。 ***
