Secondary ion mass spectrometry and x-ray absorption near-edge structure spectroscopy of isotopically anomalous organic matter from CR1 chondrites GRO 95577 (2007)

Busemann, H., Zega, T. J., Alexander, C. M. O'D., Cody, G. D., Kilcoyne, A. L. D., Nittler, L. R., ...

We located interstellar organics from a CR1 chondrite with NanoSIMS and analyzed FIB-extracted sections with XANES. D-rich material appears not associated with a functional group, whereas 15N-rich...

Coordinated isotopic and mineralogic analyses of planetary materials enabled by in situ lift-out with a focused ion beam scanning electron microscope (2007)

Correlated analyses of D- and 15N-rich carbon grains from CR2 chondrite EET 92042 (2006)

Busemann, H., Alexander, C. M. O'D., Nittler, L. R., Zega, T. J., Stroud, R. M., Bajt, S., ...

Extract from introduction: Insoluble organic matter (IOM) and matrix from primitive carbonaceous chondrites carry isotope enrichments (δD≤20000‰, δ15N≤3200‰) that are comparable to those in...

Correlated analytical studies of organic material from the Tagish Lake carbonaceous chondrite (2006)

Zega, T. J., Stroud, R. M., Nittler, L. R., Busemann, H., Alexander, C. M. O'D.

We report on correlated studies of organic material using SIMS, FIB-SEM, and TEM.

Correlated Microscale Isotope and Scanning Transmission X-Ray Analyses of Isotopically Anomalous Organic Matter from the CR2 Chondrite EET 92042 (2006)

Busemann, H., Alexander, C. M. O'D., Nittler, L. R., Zega, T. J., Stroud, R. M., Cody, G. D., ...

We discuss correlated examinations of organic matter from the CR2 chondrite EET 92042, using SIMS, STXM and other methods. We found a large, isotopically highly anomalous region of probable presolar...
