Dhofar 700

Oman

Found 2002 November 15

Achondrite (diogenite)

Twelve dark-grey stones totalling 2770 g were found in the Dhofar region of Oman. Classification and mineralogy (S. Demidova, Vernad; G. Kurat, NHMV): fusion crust is absent. The meteorite has an equigranular texture, and consists dominantly of orthopyroxene (Wo2.5–7En62–71; Fe/Mn ≈ 25 at.). Accessory minerals are clinopyroxene Wo8–25En55–66, olivine Fo63–68, plagioclase An89–95, silica, chromite, troilite and FeNi metal (0.2–3.8 wt% Ni, 0.3–0.8 wt% Co); terrestrial weathering is not significant; rare Fe hydroxide is present. The mafic silicates in Dho 700 have the low mg# that is a characteristic feature of diogenites. Specimens: 350 g plus thin section, Vernad; main mass with anonymous finder.

Dhofar 700 Rare Vesiculated Diogenite Meteorite 1.50g

 

Very limited amount available.  Collectors are not willing to part with this type easily.  In most cases, this mysterious material commands well over $100.00/gram when available!

1.50
gram part slice of Dhofar 700, a rare Diogenite type achondrite. Twelve dark gray stones totaling 2,770 grams were found in the Dhofar region of Oman in 2002.  Of the twelve, only a few very small and one large stone were found to contain vesicles. I paid top dollar to acquire the largest vesiculated stone knowing that science has yet to answer the question; “What are vesicles doing in a cumulate type rock?” This has never been observed in a Diogenite or terrestrial cumulate before and is a real mystery.
