Gao-Guenie, new name

With the recent paper by Bourot-Denise et al. (1998), the Meteorite Nomenclature Committee has decided that a new, collective name, Gao-Guenie, will be bestowed upon all meteorites formerly identified as either Gao (Upper Volta) (frequently truncated to Gao) or Guenie.ï¿½ It had been reported that two meteorite showers occurred one month apart in 1960 in the country now known as Burkina Faso.ï¿½ But the new work confirms long-held suspicions that the two meteorites are indistinguishable from each other and that there was most likely only one fall (1960 March 5).ï¿½ The confusion about this meteorite has been compounded by the fact that new stones continue to be found ~40 years after the fall and are given arbitrarily one or the other name.ï¿½ Henceforth, the official name for all meteorites from this shower will be Gao-Guenie, with the names Gao (Upper Volta) and Guenie as recognized synonyms.

Huss meteorites

The meteorites listed in Table 2 were all listed in the catalogs of Huss (1976, 1986).ï¿½ Many of these specimens are noted in Graham et al. (1985) under the corresponding entries without the letter in parentheses.ï¿½ It is likely that most are not paired with the other listed specimens.ï¿½ The names of these meteorites have now been formally approved by the Nomenclature Committee.ï¿½ In doing so, several names are abolished:ï¿½ Bethel, Elida and New Moore now become synonyms as shown in Table 3.ï¿½ In addition, Table 3 notes several other synonyms that arise out of issues related to the two Huss catalogs and the Graham et al. (1985) listings.ï¿½ See the separate entry concerning the nomenclature of stones from Kress, Texas.

Hill, UAz):ï¿½ olivine, Fa_19.3_ï¿½_0.4; pyroxene, Fs_17.2_ï¿½_0.3 Wo_1.36_ï¿½_0.27; kamacite contains 0.55 ï¿½ 0.03 wt% Co; compositions indicate H-chondrite affinity; olivine indicates shock stage S1, plagioclase indicates S2ï¿½S3, and abundant opaque shock veins suggest S3 or higher (discrepancies may be due to annealing).ï¿½ Macroscopic description (D. A. Kring, UAz):ï¿½ Some individuals are crosscut by an unusually high number of metal-rich shock veins, and some specimens are composed dominantly of metal.ï¿½ These metal-rich samples appear to be large single veins, or pockets of metal produced by intersecting veins.ï¿½ Angular chondritic clasts may have moved a few millimeters along metal-rich veins.ï¿½ Etching of centimeter-sized metal areas reveals a fine Widmanstï¿½tten pattern, bandwidth = 0.02 to 0.81 mm (average 0.32 mm).ï¿½ The composition of kamacite in metal-rich regions is the same as metal in chondritic areas (0.56 ï¿½ 0.05 wt% Co).ï¿½ The source of the metal in the shock veins appears to be the H-chondrite host, which is depleted in its normal complement of metal (4.4% rather than 15ï¿½19%).ï¿½ Specimens:ï¿½ type specimen, 49 g, and thin section, UAz; 16.5 kg mass purchased by consortium including FMNH, SI, UCLA, and UNM.ï¿½ 17.0 kg mass with finder; much of remaining material is being sold by commercial meteorite dealers.
