The Fate of Primary Iron Sulfides in the CM1 Carbonaceous Chondrites: Effects of Advanced Aqueous Alteration on Primary Components
Sheryl A. Singerling, Catherine M. Corrigan, Adrian J. Brearley
We have carried out a SEM-EPMA-TEM study to determine the textures and compositions of relict primary iron sulfides and their alteration products in a suite of moderately to heavil…
Tracing the history of an unusual compound presolar grain from progenitor star to asteroid parent body host
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We conducted a TEM study of an unusual oxide-silicate composite presolar grain (F2-8) from the unequilibrated ordinary chondrite Semarkona. The presolar composite grain is relative…
TEM analyses of in situ presolar grains from unequilibrated ordinary chondrite LL3.0 Semarkona
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We investigated six presolar grains from very primitive regions of the matrix in the unequilibrated ordinary chondrite Semarkona with TEM. These grains include one SiC, one oxide (…
Trace Elemental Behavior in the Solar Nebula: Synchrotron X-ray Fluorescence Analyses of CM and CR Chondritic Iron Sulfides and Associated Metal
Sheryl A. Singerling, Stephen R. Sutton, Antonio Lanzirotti +2
We have performed a coordinated focused ion beam (FIB)-scanning and transmission electron microscopy (S/TEM), electron probe microanalysis (EMPA)-synchrotron X-ray fluorescence (SX…
TEM analyses of unusual presolar silicon carbide: Insights into the range of circumstellar dust condensation conditions
Sheryl A. Singerling, Nan Liu, Larry R. Nittler +2
Presolar silicon carbide (SiC) grains in meteoritic samples can help constrain circumstellar condensation processes and conditions in C-rich stars and core-collapse supernovae. Thi…
