Writeup from MB 93:

Dhofar 1429                        18°32'16''N, 54°11'16''E

Dhofar, Oman

Find: 5 March 2006

Achondrite (eucrite, monomict)

History and physical description: An 89 g stone, covered with very fresh fusion crust, was found in the Dhofar region of Oman by R. Ward on March 5, 2006.

Petrography: (T. Bunch and J. Wittke, NAU) Partially recrystallized monomict breccia. Relict textures include fine-grained subophitic transitional to variolitic textures. The matrix is a mixture of finely comminuted to recrystallized zones. Narrow shock veins transect the specimen. Plagioclase in relict basalt clasts is partially converted to maskelynite.

Mineral compositions and Geochemistry: Relict basalt clasts: orthopyroxene (Fs60.3Wo2.2; FeO/MnO = 32), pigeonite (Fs51.2Wo12.3; FeO/MnO = 30), augite (Fs25Wo45.3), chromite (Cr/(Cr + Al) = 81) and metal (Ni = 0.27 wt%).

Classification: Achondrite (eucrite, monomict breccia); medium to extensive shock, minimal weathering.

Type specimens: A sample of 18.8 g is on deposit at NAU. RWard holds the main mass.

Submitted by: Ted Bunch, NAU.
