Axtell
McLennon County, Texas, USA
Found 1943, recognized 1993
Carbonaceous chondrite (CV3)
A single stone of 6.2 kg was found while ploughing. Classification and thin section analysis by Simon et al. (1994a) and Casanova and Simon (1994): olivines and low-Ca pyroxenes average Fay and Fs1, respectively, texture and oxygen isotope ratios (anlysis R. N. Clayton) are much like those of Allende. However, Axtell shows pervasive weathering of matrix minerals and has a 60Co concentration and refractory inclusions that are unlike those of typical Allende specimens. Natural and induced thermoluminescence data are also consistent with this meteorite not being paired with Allende; see Simon et al. (1994b).
