A Case for Nebula Scale Mixing Between Non-Carbonaceous and Carbonaceous Chondrite Reservoirs: Testing the Grand Tack Model with Chromium Isotopic Composition of Almahata Sitta Stone 91A
Sanborn M. E. * Yin Q.-Z. Goodrich C. A. Zolensky M. Fioretti A. M.
80th Annual Meeting of the Meteoritical Society 2017 [#6277]
“We present new Cr isotopic composition results for Almahata Sitta stone 91A. Based on the Cr isotope results, we discuss the provenance of the chondritic material in 91A and the implications for the Grand Tack model of nebula wide mixing. ”
