Scientific paper

In the four meteorites Yamato (a), (b), (c) and (d) recently found in Antarctica, the trace elements W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Th and U were determined by spark source mass spectrometry. The concentrations of these elements were also measured in the meteorites Orgueil (C1), Murray (C2), Allende (C3), Abee (E4), Allegan (H5), Mocs (L6) and Johnstown (Ah). The trace element concentrations confirm the preliminary classification of the Yamato meteorites already given earlier: Yamato (a) = enstatite chondrite, Yamato (b) = Ca-poor achondrite, Yamato (c) = carbonaceous chondrite of type 3, Yamato (d) = ordinary chondrite. The concentrations of Au and Hg are antipathetically correlated. In the achondrite Yamato (b) the concentrations of the siderophile elements W, Re, Os, Ir, and Pt depend strongly on the boiling points of these metals.
