Jiddat al Harasis 360 (JaH 360)        19°22.338’N, 55°33.778’E

Al Wusta, Oman

Found: 9 Mar 2003

Classification: Ordinary chondrite (L, melt rock)

History: One dark brown stone was discovered in the desert about 100 km SW of Haima.

Physical characteristics: One stone of 55.5 g. Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.33.

Petrography: (Bartoschewitz, Bart) Fine grained with dominantly anhedral olivine (~0.3 mm, mosaicism and undulatory extinction) in a matrix (<0.05 mm) of olivine, pyroxene and plagioclase, with accessory rounded metal and troilite. Chondrules are lacking. Short dark melt veins (approx. 1 × 0.2 mm) of mainly oxidized metal and sulfides.

Geochemistry: (Bartoschewitz, Bart and Appel/Mader Kiel) Olivine Fa22.8 - 26.8, CaO 0.1 %, Fe/Mn = 41 (at%). Low-Ca pyroxenes Fs17.2-26.7Wo2.9-0.8; Ca pyroxene Fs18.9-26.2Wo5.5-19.3. metal Ni 13.6-14.3, Co 0.8 (wt%). O-isotopes: (I. A Franchi and R. C. Greenwood, OU) δ17O=3.971‰, δ18O=5.792‰, Δ17O=0.959‰.

Classification: (Bartoschewitz, Bart and R. C. Greenwood, OU) Chondrite (L melt rock)

Specimens: A total of 11.1 g is on deposit at the University of Kiel. A sample of 4.3 g and one thin section are on deposit at the Bartoschewitz Meteorite Lab. The main mass is in anonymous hands.
