Writeup from MB 86:
Yafa Yafa province, Yemen Fall 2000 July 15, 14:45 h GMT Ordinary chondrite (H5) A main mass of ~5 kg and a second mass of ~700 g are known. Many witnesses reported a fireball over a wide area from Ma'raban to Aden (some 95 km to the south-southwest) to Ad Dhala (70 km west-southwest of Ma'raban) and many in the region reported associated sound effects. The larger stone was collected on the day of the fall, probably within 2–3 h of the event. The smaller stone was collected the following day. Classification and analysis (G. C. Wilson, UToron): Macroscopically, the fall is a breccia, with welldeveloped fusion crust and a pale interior. Olivine, Fa19.4; orthopyroxene, En81.3Fs17.3Wo1.4; kamacite, 0.56 wt% Co and 6.78 wt% Ni. Tetrataenite, averaging 50.3 wt% Ni, is an accessory mineral. Shock stage, S2; negligible degree of weathering, consistent with recent fall. See also Wilson and Rucklidge (2001). Specimens: type specimen, 600 g, Yemen; 93 g and polished thin section, GSC; main mass believed to reside with the finders (as of 2001 September 28). | ||||||||||||||||
