It is a much coarser soil that other Apollo samples (figure 4). McKay et al. (1972) and Simon et al. (1982) studied the petrology of this soil and compared it with other Apollo 14 soils. It is similar except that there are fewer agglutinates. Figure 2 :Rocky rim of Cone Crater with cart for carrying tools and samples. NASA AS14-64-9121. Bulletin 4700 MicrowaveC. C. Schnetzler and D.

Earth Planet Indigenous abundances of siderophile elements in the lunar Substantial indigenous abundances of siderophile elements have been found to be present in the lunar highlands. The abundances of 13 siderophile elements in the parental magma of the highlands crust were estimated by using a simple model whereby the Apollo 16 highlands were regarded as being a mixture of three components (i.e. cumulus plagioclase + intercumulus magma that was parentel to the Lunar Elemental Distribution SpringerLinkSep 21, 2017 · Schnetzler CC, Nava DF (1971) Chemical composition of Apollo 14 soils 14163 and 14259.

Trigila :1046 et g.,Apollo 14. Soils and breccias from Apollo 14 are nearly 3 times richer in siderophile elements (Ir, Re, Au, Ni) than the soils from Apollo 11,12 and Luna 16. Intrinsic lunar abundances of these elements are now known for the parent rocks of Apollo 14 soils, but are probably low.
