This award will support the development of techniques for making in situ analyses of oxygen and sulfur isotopes in oxide, silicate and sulfide minerals using fluorine gas and laser heating for the liberation of oxygen and sulfur. The technique development work will be carried out in the Geophysical Laboratory of the Carnegie Institution of Washington which will provide necessary equipment as well as technical and scientific personnel for the project. It is anticipated that the improved method of stable isotope analysis will have application in a wide variety of investigations where high-resolution, in situ, isotopic analyses are required including, for example, siliceous cements binding detrital grains in sandstones, phenocrysts in plutonic and volcanic rocks, zoned porphyroblasts in metamorphic rocks, and crustiform deposits of sulfide, silicate, and oxide minerals in ore deposits.

该奖项将支持开发氧化物，硅酸盐和硫化物矿物质的原位分析，并使用氟气体和激光加热来解放氧气和硫化物。该技术开发工作将在华盛顿卡内基研究所的地球物理实验室进行，该实验室将为该项目提供必要的设备以及技术和科学人员。 It is anticipated that the improved method of stable isotope analysis will have application in a wide variety of investigations where high-resolution, in situ, isotopic analyses are required including, for example, siliceous cements binding detrital grains in sandstones, phenocrysts in plutonic and volcanic rocks, zoned porphyroblasts in metamorphic rocks, and crustiform deposits of sulfide, silicate, and矿床中的氧化物矿物质。
