The concentrations of 41 major, minor and trace elements were determined in Haverö ureilite. In addition to the analysis on bulk samples a number of separates were measured, too, including hand‐picked samples of the dark carbonaceous, diamond‐rich inclusions and two metal fractions. It was found that one metal fraction had an extraordinarily high Ir/Au‐ratio of 19. According to the concentrations of the noble metals and of nickel, gallium, tungsten and rhenium this metal represents, most probably, the siderophile portion of a high temperature condensate, i.e., the pattern of these elements is very similar to that found in Allende inclusions (Wänke et al., 1972)
