Metbase description: Show/Hide
A mass of 131lb, said to have been seen to fall in the Wadee Banee Khaled during a thunderstorm in 1863, was in 1885 obtained from a Persian agent by the Nat. Hist. Mus., London, A.L.Graham et al., Cat. Met., 1985, p.365. Description and analysis, L.Fletcher, Min. Mag., 7, p.179. In 1893 a second, much weathered mass of 137lb was similarly obtained by the Nat. Hist. Mus., London. Another mass of 25lb and other small pieces, 114g together, were found near a series of meteorite craters, H.St.J.Philby, The Empty Quarter, London, 1933, p.365 (M.A.5-409). Associated with the iron were found masses of white and black pumiceous silica-glass. The black contains both Fe and Ni, as innumerable minute metallic globules, clearly of meteoritic origin, A.L.Graham et al. [loc. cit.]. Description, L.J.Spencer, Min. Mag., 1933, 23, p.387. Mentioned, D.A.Holm, Am. J. Sci., 1962, 260, p.303. Further analysis, 7.62% Ni, 21.3 ppm Ga, 38.4 ppm Ge, 6.0 ppm Ir, E.R.D.Scott et al., GCA, 1973, 37, p.1957. Metallographic description, includes Nejed and Nejed (no.2), V.F.Buchwald, Handbook of Iron Meteorites, Univ. of California, 1975, p.1273. One large cone-shaped mass of 2200kg, found 400 m SSW of the main crater in 1965, and another mass of 200kg, found 575 m S of the main crater in 1966, are on display at the Univ. of Riyadh, R.S.Clarke,Jr. and A.A.Almohandis, Meteoritics, 1981, 16, p.303.
