Dhofar 1767 (Dho 1767)        18.817°N, 54.766°E

Zufar, Oman

Found: 2013 Jan

Classification: HED achondrite (Howardite)

History: Found by a prospector in January 2013.

Petrography: (A. Wittmann, WUSL; A. Irving, UWS) Well-consolidated breccia composed of clasts (~1 mm in size) of orthopyroxene (~15 vol.%, of more than one composition based on BSE imaging), calcic plagioclase, exsolved pigeonite, unexsolved pigeonite, metal (as clasts up to 0.1 mm containing both taenite and kamacite), olivine, chromite, ilmenite, fayalite and silica polymorph. Celestite occurs in mm-long vein-like zones of and FeNi metal grains typically show oxidized rims.

Geochemistry: (S. Kuehner, UWS; A. Wittmann, WUSL): Diogenitic orthopyroxene (Fs20.4-24Wo1.4-3, FeO/MnO = 29-31), orthopyroxene (Fs39.9Wo3.8, FeO/MnO = 30), pigeonite (Fs51.9Wo7.3, FeO/MnO = 27), host orthopyroxene (Fs61.8Wo2.7, FeO/MnO = 32), clinopyroxene exsolution lamellae, Fs27.3Wo42.1, FeO/MnO = 32). olivine (Fa57.5, FeO/MnO = 49; Fa84.7, FeO/MnO = 42), plagioclase (An90Or0.4).
