Writeup from MB 100:

Dhofar 1527 (Dho 1527) 19°23.37’N, 54°28.02’E

Zufar, Oman

Found: Mar 2009

Classification: Lunar meteorite (feldspathic breccia)

History: A complete stone recovered by Jim Labenne in March, 2009.

Petrography: (H. Haack, NHMD) Metal-rich clast-laden vitric breccia consisting of glass and fine-grained mineral debris (mostly pyroxenes, olivine, anorthite and metal), melt breccia fragments and polycrystalline igneous clasts. Clast sizes to 3 mm. Mineral clasts include anorthitic plagioclase, low-Ca pyroxene, olivine, kamacitic and troilite. Lithic clasts include rare basalts (composed of plagioclase and pyroxene) and troctolite (composed of plagioclase and olivine). Metal grains are partially oxidized. Some olivine grains are partially to totally altered by weathering. Veinlets filled with alteration products are abundant.

Geochemistry: Olivine (Fa_20-37), plagioclase (An_93-98), pigeonite (Fs_21-29Wo_8-11), and augite (Fs_6-8Wo_32-36). Bulk composition: (R. Korotev, WUSL): 25% Al₂O₃, 8.0% FeO, 8.2% MgO, 1200 ppm Ni, 1.1 ppm Sm, 89 ppb Ir, 0.5 ppm Th.

Classification: Achondrite (lunar, feldspathic breccia).

Specimens: A total of 8.56 g is deposited at NHMD.
