Lut 002        30°17’26"N, 59°23’55"E

Kerman, Iran

Found: 2013 Feb 8

Classification: Ordinary chondrite (H4)

History: A single stone found during an expedition in the Lut desert of Iran, on sand dunes known to locals as Rig-e Yalan. A 42.3 g end piece was donated to Cascadia on May 1, 2013.

Physical characteristics: Physical: Cut face shows a reddish-brown to dark gray interior with numerous small chondrules and two large chondrules. Exterior is covered by a dark brown weathering patina.

Petrography: (M. Hutson and A. Ruzicka, Cascadia) In thin section, the specimen shows numerous small chondrules (typically <0.5 mm diameter) surrounded by a mixture of weathering products (iron oxides and calcium sulfate), troilite and finer-grained silicates. About 80-90% of the metal and sulfide have been replaced by weathering products. Devitrified glass is present in the mesostases of some chondrules.

Geochemistry: BSE imaging shows that the meteorite is equilibrated. Compositions of measured phases in the host meteorite are consistent with an H chondrite, and include olivine Fa_17.0±0.3 (N=10), and low-Ca pyroxene Wo_1.2±0.2Fs_14.9±0.2En_83.9±0.3 (N=10).

Classification: H4 chondrite based on texture and mineral chemistry.

Specimens: A 38.7 g end piece, one polished thin section, and a stub are on deposit at Cascadia. Mr. Maziar Nazari and Mr. Kiyan Babazadeh hold the main mass (PO Box 17665-414, Tehran, Iran).
