Description

The NanoSIMS 50L at NASA JSC was used to analyze concurrently the 12C, 13C, 16O, 17O, 18O, 28Si, and 24Mg16O in sample OREX-501018-100 through raster ion imaging. On the sample, isotope maps were collected for 20 micrometer fields of view. These 20-micron regions were analyzed sequentially during chained analyses. The data were collected with the goal of identifying presolar grains. A cluster of forsterite grains were also targeted for O isotopic analysis. San Carlos olivine (16O, 17O, 18O) and graphite (12C, 13C) were measured as isotopic standards.
