Found February 6, 2003
18° 49.71' N., 54° 38.37' E.

A single 499 g stone was found in Oman. Analysis and classification was conducted at Vernadsky Institute of Geochemistry and Analytical Chemistry, Russia (M. Ivanova) and Dhofar 1275 was determined to be an ordinary chondrite which has been extensively metamorphosed to the point of recrystallization, and therefore has been assigned a petrologic type of 7. This meteorite is very weakly shocked (S2) and has experienced complete oxidation of metal and troilite (W4) during its residence on Earth.

Dhofar 1275 is an extremely rare subtype among the L chondrite grouping. In addition to Dhofar 1275, only two other L7 chondrites are non-Antarctic (most Antarctic specimens compose a single pairing group): Forrest 028, which was found in Western Australia and will likely never be traded among collectors, and NWA 1839, which contains O-isotopic values that indicate it originated on the CV parent body rather than the L chondrite parent body.

A brief synopsis of the history pertaining to the adoption of the type 7 petrologic subtype can be seen on the Dhofar 011 (LL7) page. The specimen of Dhofar 1275 shown above is a 0.60 g cut fragment from along the fusion-crusted edge.
