This issue contains preliminary descriptions and classifications of meteorites that were completed after the publication of issue 24(2), September 2001. Specimens of special petrologic type (e.g., carbonaceous chondrite, unequilibrated ordinary chondrite, and achondrite) are described separately unless they are paired with previously described meteorites. However, some specimens that are not of special petrologic type are listed only as single-line entries in Table 1. For convenience, new specimens of special petrologic type are recast in Table 2.
Macroscopic descriptions of stony meteorites were written at NASA/Johnson Space Center. These descriptions summarize hand-specimen features observed during initial examination. Classification is based on microscopic petrography and reconnaissance-level electron microprobe analyses of polished sections prepared from a small chip of each meteorite. For each stony meteorite, the sample number assigned to the preliminary examination section is included. In some cases, however, a single microscopic description is based on thin sections of several specimens believed to be members of a single fall.
