Secondary ion Mass Spectrometry (SIMS) spot data of sample OREX-803431-100 for carbon isotopes. The grains of aggregate imaged are pressed into an indium metal mount. The session carbon isotopic standard was called C905 and it has an d13C composition of -28.0‰. C905 is a mixture of silica nanopowder bonded with Ceramacast 905 (AREMCO; House et al., 2015).

PDF files showing images of the various SIMS spots with their associated file names and a PDF showing the output of an excel sheet showing the order of the analyses, raw isotopic values, and notes. There is also a zip file containing all of the Cameca ais files generated and used to generate the data for each valid spot analysis. Finally, there is a .cvs file showing the processed isotopic values for this SIMS session.
