Old Homestead 003 31°27’10"S, 127°53’25.8"E Western Australia, Australia Found: 2002 Classification: HED achondrite (Howardite) History: A single mass was found by P. Devine near the reported 1991 find-site of the Old Homestead 001 howardite (MetBull 74). Physical characteristics: Rounded, compact stone weighs 1.78 kg, has a pitted light brown surface lacking fusion crust. While the surface is weathered the interior remains fresh. Petrography: (A.W.R. Bevan, WAM, and T. Kennedy, UWA) Breccia of lithic clasts including eucritic (some showing ophitic texture) and minor diogenitic components set in a clastic, welded, melt matrix of mineral fragments and glass. Abundant pyroxene and plagioclase feldspar, other minerals include olivine, chromite, ilmenite and Fe-Ni metal. Petrologically distinct from Old Homestead 001. Geochemistry: (A. Bevan, P. Downes, WAM; E. Hancock, GSWA; and T. Kennedy, UWA): Rare olivine (Fa3.9-45.5), pyroxene (Fs8.9-67.5Wo1.2-86.0) and plagioclase (An88.2-96.8Ab3.1-10.9Or0.06-0.77). Oxygen isotopes (I. A. Franchi, OU) replicate analyses δ17O = 2.37, 2.30; δ18O = 5.02, 4.88; Δ17O = -0.232, -0.235 (all per mil). Classification: Achondrite (howardite). Not paired with Old Homestead 001.
