Find: 2001

Achondrite (ureilite)

History: On 27 August 2001, M. Farmer purchased a 24.5 g sample in Quarzazate, Morocco.

Petrography: (P. Warren, UCLA) The meteorite is mostly composed of olivine and pigeonite with minor orthopyroxene. The Px/(Px+Ol) ratio is ~0.4. Olivines have rims with reduced chemistry.

Geochemistry: Olivine (cores Fo89.6; CaO = 0.33; Cr2O3 =  0.64 [both wt%; n = 47]), pigeonite (En82.8Wo7.9; Cr2O3 = 0.99, Al2O3 = 0.57, MnO = 0.47 [all wt%; n = 17]), orthopyroxene (En86.4Wo4.7; Cr2O3 = 0.95, Al2O3 = 0.62 [both wt%; n = 3; all analyses by EMP]). Based on INAA data (UCLA), typical ureilite trace-element composition (except for weathering effects): Sc = 9.4, Ni = 720, Zn = 330 (all µg/ g); Ir = 124, Au = 16.1 (both ng/g).

Classification: Achondrite (ureilite); low shock.

Specimens: A 5.86 g type specimen is on deposit at UCLA. MFarmer holds the main mass.
