Found 1889-1962

Ordinary chondrites

A detailed study of 52 meteorites recovered from Travis County was undertaken by McCoy et al. (1995a). They found two distinct meteorites: Travis County (a), a H5(S4)W3 shock blackened chondrite, represented by 41 specimens with a total weight of 175.4 kg; and Travis County (b), a H4(S2)W3 chondrite with rare chonditic clasts of H group parentage, represented by 11 specimens with a total mass of 5.9 kg. The samples are in the Oscar Monnig Collection, Texas Christian University, Fort Worth, Texas. The original Travis County meteorite, found in 1889, listed in Graham et al. (1985) belongs to Travis County (a). Classification and analysis: Travis County (a) = olivine Fa16.2-16.9; orthopyroxene Fs15.3-15.8; Wo1.0-1.1; Travis County (b) = olivine Fa16.1-18.9; ortho-pyroxene Fs16.0-16.3; Wo1.1-1.2; Timothy J.
