The source of sublimates on the Apollo 15 green and Apollo 17 orange glass samples.

摘要: Elemental analyses of the thin film micromounds which coat surfaces Apollo 15 green glass and 17 orange are reported. It is thought that Zn, Ga, Pb, Cu, Tl, S, F, Cl condensed as a sublimate on outside surface these particles in lava fountains about 3.4 3.6 b.y. ago (Apollos 17, respectively). The heavy metals enriched samples may have been mobilized halide- sulfide-rich vapor, while source elements be sulfide- halide-rich pyroxenite inside moon. isotopic composition lead individual was determined, considered with respect to evolution region. similar has mixed into other soils breccias at nearby sites.
