Yabrin 003 (0803-4)                                                              23°18.913’N, 48°37.793’E

Saudi Arabia (Ash Sharqiyah)

Found 19 March 2008

Achondrite (Acapulcoite)

History: A single stone with a mass of 21.05 g was found by Edwin Gnos, Beda Hofmann, Mohammed Halawani, Yahia Tarabulsi and Mohammed Hakeem during a search for meteorites.

Physical characteristics: Irregular stone without fusion crust, 21.05 g.

Petrography: (E. Gnos, MHNGE; B. Hofmann, NMBE): Equigranular recrystallized texture with triple junctions, mean grain size 160 mm. Olivine (Fa11.3-11.9; FeO/MnO = 20.9-28.8), orthopyroxene (Fs10.3-11.0Wo1.2-2.7; FeO/MnO = 12.3-16.5), plagioclase (An16.4-17.6Or3.1-4.5). Chromite, apatite, troilite, kamacite, graphite (in kamacite) and schreibersite are also present. The meteorite is unshocked (S1).

Geochemistry: Bulk Fe by XRF is 18.8%. Oxygen isotopes (I.A. Franchi and R.C. Greenwood, OU): d17O = 1.13, d18O = 4.04, and D17O = -0.98 (mean of two replicates) (D17O=d17O-0.52 d18O).

Classification: Based on petrography, mineral chemistry and oxygen isotopes this meteorite is an acapulcoite, shock grade 1, weathering grade 2.

Type specimen: 4.3 g and one polished thin section at MHNGE, main mass: Saudi Geological Survey, Jeddah, Saudi Arabia.
