Thumrayt 001 17°35'N, 54°21'E Thumrayt, Oman Find: November 2006 Pallasite (main group) History: The meteorite was found by M. Farmer in November 2006. An additional 41 pieces within an area of 0.5 miles by 3.5 miles were collected by M. Farmer and R. Ward. Physical characteristics: The meteorite was found as a small strewn field comprising of 42 pieces with a total mass of 2.48 kg. The surface of the meteorite is weathered, it displays exposed crystals and the metal portion is gray to reddish brown. Petrography: (D. Schrader, UAz) The meteorite is predominantly Fe,Ni metal, with angular (larger crystals) to sub-rounded (only the small crystals) olivine crystals ranging in apparent long axis from 0.02 to 4 cm. The crystals are sometimes associated with schreibersite, troilite, chromite, and calcium phosphate. One area of chromite borders both olivine and Fe,Ni metal and contains angular and rounded troilite grains. Mineral compositions and Geochemistry: (D. Schrader, K. Domanik, and D. Hill, UAz) Fo83.8-87.3 (average Fa86.7±0.4); kamacite (Ni = 4.7 ± 1.2, Co = 0.6 ± 0.04 [averages, wt%]), and Ni-rich Fe,Ni metal (up to Ni 46.5 wt%), schreibersite, troilite, Ca phosphate, chromite. Bulk composition: (D. Schrader, D. Lauretta, and J. Goreva, UAz; ICP-MS) Fe = 87.7, Ni = 11.0, Co = 0.56, S = 0.36, P = 0.43 [all wt%]; Cr = 3043, Ge = 4.4, Ga = 11.2, Cu = 235, Pt = 10.4, As = 13.9 [all ppm]; Se = 2234, Mo = 34879, Ru = 2230, Pd = 1133, Rh = 0361, V = 11294, Sb = 0091, Re = 0120, Mn = 307125, Ag = 0553, and Zn = 2257 (all ppb). Os and Ir below detection limit. Classification: Pallasite (main group). Type specimens: A total of 21 g of sample are on deposit at UAz. RWard holds the main mass. Submitted by: D. Schrader, UAz. | ||||||||||||||||
