Here we go again - Bencubbin time once more :-) Best regards,
Bernd MASON B. (1962) Meteorites (John Wiley and Sons, Inc., p. 128): A few mesosiderites (e.g., Bencubbin, Patwar) have almost pure MgSiO3 as the pyroxene; in these meteorites nickel-iron is predominant, and they should probably be classed as irons with silicate inclusions. GEHRELS T. (1979) Asteroids (UoA Press, Part VI, Origin of Iron Meteorites, p. 918): There are other metal-rich meteorites with well-analyzed metal. Bencubbin, Weatherford and Mt. Egerton have chondritic levels of Ir (2-3 �g/g) (Kallemeyn et al. 1978; Scott and Wasson 1976). Bencubbin has been identified as an impact-produced breccia. Its metal has low concentrations of volatile siderophiles like Ga and Ge which show a correlation between abundance and condensation temperature. The only known meteorites containing silicate and appreciable metal with non-chondritic levels of Ir are those in iron group IB. ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
