Dhofar 1286 18°25′579′′N, 54°25′719′′E Oman Find: December 2005 Achondrite (eucrite, polymict) History: Two pieces of meteorite weighing 898 g in total were found on a sandy surface in the desert of Oman. The distance between the fragments was about 30 m. Joined together, the fragments form an almost complete individual sample with ~10% missing. Petrography: (Lorenz, Vernad and Brandstätter, NHMV) On the unbroken surfaces, black fusion crust is partly preserved. The meteorite is a polymict breccia consisting of fragments of medium- to coarse-grained metamorphosed gabbroic rocks and fine- to medium-grained subophitic basaltic rocks. Minor equigranular metamorphic pyroxene-feldspar rocks, melts, and melt matrix breccias are present. The rock fragments are situated in a fine-grained clastic matrix and comprise 60 vol% of the whole meteorite. Accessory minerals are troilite, chromite, ilmenite, silica, Ca phosphate, and metal Fe,Ni. Geochemistry: Pyroxene (En35.1–62.8Wo1.8–5.7; Fe/Mn = 30) with exsolved augite (En21.1–54.2Wo21.1–38.9). Classification: Achondrite (eucrite, polymict). Specimens: A 20.6 g type specimen and one polished section are on deposit at Vernad. An anonymous finder holds the main mass. | ||||||||||||||
