Writeup from AMN 38(2):
Reclassification of RBT 04133
RBT 04133 was classified as a CR2 in the February 2008 (vol.31 No. 1) newsletter. More detailed information has led to a better understanding of this sample, which we here re-classify to CV3 (reduced), based on the study of Davidson et al. (2014). Quoting from their paper: “Data presented here conflict with its initial classification as a CR2. Petrographically, RBT 04133 appears to be a CV3red, based on the presence of large CAIs and chondrules, the apparent lack of magnetite, and a matrix composition of Fa59–60. This is in agreement with its whole-rock C, N, and O-isotope compositions, and the Raman spectral characteristics of its IOM.” | ||||||||||||||||||||
