Chemical composition of boulder-2 rocks and soils, Apollo 17, Station 2The bulk and trace element composition of five small samples from four rocks is remarkably similar. This result indicates that the metaclastic rocks studied are relatively uniform in their chemical composition. The elemental abundances found in the study are presented in two tables and the implications of the data are considered, giving attention to siderophiles, atmophile elements, and questions of element correlations. The 'dark mantle' valley soil 75081 at Camelot Crater is low in siderophiles. Since the soil is low in alkalis, a derivation from low-alkali mare basalt is suggested. The identical volatile contents in the surface soil 72461 and the 4 cm depth soil 72441 under a 0.7 m boulder argue against any surficial volatization by galactic and solar particles.
