Results of a study of the structural-chemical characteristics of surface layers of particles of Apollo-15 15426 samples (green glass) and Apollo-17 74220 samples (orange soil) are found to agree with the hypothesis of their endogenic origin as due to condensation from a gas cloud of volcanic origin. The particles are characterized by a two-layer structure with enrichment of the surface layer by specific volatile components (S, Zn, Pb, Fe, and Cl); however, the thickness of the 'fumarole' film in 15426 is about three times smaller than that of 74220 and it is more oxidized. In addition, the oxygen fagacity of the initial magma of 74220 was higher (of the order of 10 to the -10th to 10 to the -11th).
