Dhofar 1528

Zufar, Oman
Found: Jun 2009
Mass: 213.2 g (1 piece)

Lunar meteorite (feldspathic breccia)

History: Complete individual recovered by Luc Labenne in June, 2009.

Petrography: (H. Haack, NHMD). Clast-laden vitric breccia consisting of fine-grained mineral debris (mostly pyroxenes, olivine and anorthite) and polycrystalline igneous clasts. Clast sizes to 2 mm. Mineral clasts include anorthitic plagioclase, low-Ca pyroxene, olivine, spinel and rare kamacitic, chromite, and troilite. Lithic clasts include rhyolite (composed of K-rich rhyolitic glass with Ca-rich ferrolithic pyroxene microlites) and troctolite (composed of olivine, plagioclase, and Cr-poor spinel). Metal grains are partially oxidized. Many of the olivine grains are partially to totally altered by weathering.

Geochemistry: Olivine (Fa8-27), Plagioclase (An95-99), augite (Fs21-29Wo8-11). Bulk composition: (R. Korotev, WUSL): 24% Al2O3, 6.0% FeO, 9.1% MgO, 265 ppm Ni, 2.2 ppm Sm, 5 ppb Ir, 1.4 ppm Th.

Classification: Achondrite (lunar, feldspathic breccia).

Specimens: A total of 20.0 g is deposited at NHMD.

Randy Says…

Dhofar 1528 is a feldspathic lunar meteorite. I suspect that it’s unpaired with any of the other lunar meteorites from Oman, despite being found <10 km from Dhofar 025 and it’s pairs.
