ANSMET meteorites
(For other Antarctic meteorites, see Frontier Mountains.)

Appendix 1 brings up-to-date the list of officially announced meteorites from the U.S. Antarctic Meteorite (ANSMET) program. 7298 meteorites were previously listed in the Meteoritical Bulletin, no. 76, 1994 January, and no. 79, 1996 July; these meteorites bring the total to 7794. The meteorites in Appendix 1 were published in the Antarctic Meteorite Newsletter (AMN), issue 19(2) (1996), 20(1) and 20(2) (1997), and 21(1) (1998). Listed are the classifications, masses, degrees of weathering, olivine and pyroxene compositions, natural thermoluminescence levels, pairing information, ice fields upon which the meteorites were found, and bibliographic information, all sorted by sample name. Note that meteorite pairings may be tentative.

El Hammami
23�17'N 10�49'W

In 1997 January, an unknown mass of material, possibly broken apart from a single large stone, was sold to meteorite collectors by nomads near the town of Mhamid, Morocco; this material has since been resold under the names Mhamid and Hamada du Draa. The nomads claimed that this meteorite was found to the south, in Algeria (~29�50'N 5�50'W), in the direction of a fireball seen in 1995 January. In 1997 September, the same nomads shipped a fragment of a meteorite that they claimed was seen to fall on 1997 August 10 to Mr. Edwin Thompson. In 1997 November, Thompson traveled to Mauritania and collected six fresh-looking stones totaling ~200 kg (individual masses of 80, 51, 30, 26, 8, and 4 kg) at the base of the El Hammami Mountains in Mauritania (1000 km southwest of Mhamid, Morocco), probably in the place where they fell; fragments of these have been sold by Thompson and other dealers under the name El Hammami. Classification and mineralogy of El Hammami stones (A. Rubin, UCLA): olivine, Fa18.8; pyroxene Fs16.7Wo1.4; shock stage S2; contains metal veins; petrologic type 5. Classification and mineralogy of Hamada du Draa stones (D. Weber, M�n): olivine, Fa19.2; pyroxene Fs17.4; shock stage S2; contains conspicuous metal-rich veins; petrologic type 5/6; some of the material appears weathered and rusts easily, but the bulk is quite fresh. Specimens from El Hammami stones: ~100 kg, Thompson; type specimen, UCLA. Specimens originally called Hamada du Draa are now scattered in private collections, and some may remain in Morocco; type specimen, ~1 kg, M�n.

Because all of the above-described material seems likely to represent a single fall, the name El Hammami shall be the official collective name. Mhamid and Hamada du Draa should be considered only as unofficial synonyms for El Hammami. The total known mass of material is probably ~240 kg.

Elqui
unknown location

Specimens: main mass, LSC; type specimen, UCLA.

30�50'S 127�30'E (�15')

A stone of ~60 g was found by a rabbit hunter in the same area where the large masses of the Mundrabilla iron were found, perhaps 15 km north of the railway. This stone is also informally known as G'Day. Description: contains carbonaceous chondrite (CC) clasts (Zolensky et al., 1996); on the basis of the abundance of CC clasts, this meteorite is probably not paired with Mundrabilla 018 (D. Kring, pers. comm.) and is possibly paired with Old Homestead 001 (F. Wlotzka, pers. comm.). Specimens: 30 g, Haag.

Saharan meteorites from Libya

414 meteorites were recovered from the Libyan Sahara in 1996 and 1997, including the regions Hammadah al Hamra (HaH) and Dar al Gani (DaG). Table 5 lists 197 of these meteorites (see also Meteoritical Bulletin, Nos. 80 and 81), along with one recovered in 1998. Noteworthy finds are a winonaite (HaH 193), a group of CO3 chondrites from DaG that are probably paired, two CK chondrites (DaG 250 and DaG 275, possibly not paired), a eucrite (DaG 276), two ureilites (DaG 319, polymict, and DaG 340), a CH chondrite (see separate listing for HaH 237), and a lunar meteorite (see separate listing for DaG 400). Many pairings are possible among these meteorites.

Saharan meteorites from Niger

Ten chondrites (Table 6) were found in the sandy deserts of north-central Niger by an expedition sponsored by GEO magazine to the Tenere region of the Sahara. Classifications and mineralogy by P. Scherer, H. Schulze, F. Wlotzka and J. Zipfel (MPI). Tiffa 005 and Tiffa 006 seem to be paired, and Tiffa 001 may also be a member of this group (based on noble gas analysis). The EL chondrite, Grein 002, contains 0.5 wt% Si in kamacite. Specimens: main masses, Guhr; type specimens, Hamb and MPI.

Saharan meteorites from unknown locations

These meteorites (Table 7) have been collected by Mr. Marc Labenne and his family in the Sahara. Mr. Labenne will not disclose the exact locations of these meteorites at the present time. See separate entry, above, for Sahara 97096. The LL7 chondrite, Sahara 97037, is very well recrystallized, with no evidence of chondrules; a large fraction of pyroxenes are Ca-rich (Fs12.0Wo42.8); feldspar (Ab86.1An10.4) and phosphates (merrillite and apatite) make millimeter-sized associations; most metal grains are oxidized, but those that remain are very Ni-rich (61.7 wt% Ni, 1.9 wt% Co). Specimens: main masses, Labenne; type specimens as shown in Table 7.

San Borjita
27�33'31"S 56�8'4"W

A 12.3 kg stone was found by Mr. Don Torres and an unidentified truck driver shortly (perhaps a few days) after witnessing a large fireball. However, the moderately weathered condition of the stone casts a degree of doubt on whether the recovered meteorite actually fell in the 1983 event. Classification and mineralogy (T. McCoy and S. Russell, SI): olivine, Fa24.4; pyroxene Fs19.8Wo0.8; shock stage S3; weathering grade W2. Specimens: main mass with Mr. Alejandro Marin of Posadas, Argentina; one fragment possibly retained by truck driver; type specimen, 14.4 g, SI.

Sand Creek
39�25.8'N 99�59.7'W

A 2.443 kg stone was found by a farmer while plowing a grain field. Classification and mineralogy (T. J. McCoy, SI): olivine, Fa19.1�0.4; pyroxene Fs17.1�0.3Wo1.2�0.2; shock stage S4; weathering grade W2; probably not paired with Penokee or Morland, which have different shock features. Specimens: main mass, Reed; type specimen, SI.

Sappa
39º50.66'N 100º30.6'W

A 5.95 kg stone was found in a gravel pit by Mr. Paul Tansey. Classification and mineralogy (A. Rubin, UCLA): olivine, Fa25.1; pyroxene Fs21.3Wo1.6; shock stage S3; weathering grade W2. Specimens: main mass, UCLA.

Silao
20�56'N 101�23'W

A big explosion and light phenomena were widely witnessed around Silao on 1995 March 12. Mr. F. Solorzano recovered a 1460 g, completely crusted stone later that day in a field 1 km east of the city. Several smaller pieces totaling ~250 g were recovered later. Classification and mineralogy (J. Otto, Frei): olivine, Fa19.3; pyroxene Fs17.1Wo0.6; shock stage S4; weathering grade W1; contains small shock veins. Specimens: main mass, Mr. Dieter Heinlein, Lilienstra�e 3, D-86156 Augsburg, Germany; type specimen and thin section, Frei.

Snyder Hill
Find location map (357 Kb file)
32º9.5'N 111º6.8'W

Two fragments of a single mass, ~570 g and ~590 g, were found on a hill by Mr. Dave Johnson and his brother while searching for more pieces of the Cat Mountain meteorite. Classification and mineralogy (D. Kring, UAz; C. Moore, ASU): olivine, Fa24; pyroxene Fs20Wo1; 1.01% Co in kamacite; may be partially shock-melted. Specimens: type thin sections, UAz; main mass split between finder and Haag.

Tiffa 001-006, see Saharan meteorites from Niger

Turriff
35º29'S 142º36'E

A 218 g stone was found by David Rowney while he was plowing a paddock. Classification and mineralogy (Bill Birch, Vict): olivine, Fa24; pyroxene Fs20Wo0.2; feldspar present; kamacite Fe92.9Ni6.5Co0.6; chondrules abundant and distinct. Specimens: main mass, Vict.

Valencia
39�0'N 0�2'W

A 33.5 kg stone has long been in a collection at the University of Valencia, where it has been known as simply "the meteorite." There have been several historic falls in this region with which the present stone might be associated: the Oliva-Gandia fall of 1520 and a possible fall near Valencia in 1603, both having no known specimens. The Olmedilla de Alarc�n fall of 1929 is also an H5, but has a light-dark structure and shock veining, neither of which is present in this specimen. Description and classification (Francisco Anguita and Fina Mu�oz Sanz., UCM; Jesus Martinez Frias, MNCN): olivine, Fa18.0; pyroxene, Fs15.9. Specimens: contact Juan Usera, UV.
