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. ***

小行星9413693 该合同提供一半的资金，用于购买建造用于分析硅酸盐和氧化物矿物中氧同位素比率的紫外激光微探针所需的组件。激光微探针将在华盛顿卡内基研究所的地球物理实验室设计、建造、安装和运行。华盛顿卡内基研究所承诺提供完成该项目所需的剩余资金。激光微探针系统的发展，原位微量分析氧同位素浓度，预计将在地质系统中的稳定同位素变化的解释产生很大的影响，允许测量同位素的变化，以几微米的空间分辨率，可比的规模上，矿物样品保存在生长过程中继承的同位素分区。 ***
