Classification of all meteorites in Table 1 & 2 was done using electron microprobe analysis. Petrologic types are determined by optical microscopy and are assigned based on the distinctiveness of chondrule boundaries in thin section and thin section photographs. Those undertaking detailed study of any of the meteorites classified in this newsletter should use caution. It is recommended that a polished thin section be requested to accompany any chip and appropriate steps for a more detailed characterization should be undertaken by the user.
