Jan 01, 2018 · The authors perform basic research on lunar simulant development based on basalt samples having similar chemical and mechanical properties to those of lunar soil, with reference to lunar soil data reported under the Apollo program. C. C., and Nava, D. F. (1971). Chemical composition of Apollo 14 soils 14163 and 14259. Earth Planet Development and Geotechnical Engineering Properties of Oct 25, 2017 · Table 4 compares the chemical compositions of KLS-1 and lunar soil 14163. KLS-1 consists of 48.0% silicon dioxide (SiO2), 15.3% dialuminum dioxide (Al2O2), 8.38% calcium oxide (CaO), 4.75% ferric oxide (Fe2O3), 6.64% iron oxide (FeO), and 9.64% magnesium oxide (MgO). Evidence for diverse lunar melt compositions and mixing lithologies. Apollo 14 soil samples 14163 and 14259 were chosen due to the presence of previously documented felsic components in the glass (Aitken et al., 1971; Labotka et al., 1980; Papike et al. 1982). Because zircon is more common in dierentiated felsic rocks, the likelihood of nding zircon in these soil samples is presumed to be higher.

K, Rb, and Sr concentrations and Sr isotopic composition are reported for hand-picked fractions from the 175- to 1000-m Apollo 12 fines samples 12032 and 12070. In addition, two <1-mm bulk fines samples, 14163,160 and 14259,21, from Apollo 14 were Third Lunar Science Conference Table of ContentsMorphology and Chemical Composition of Metallic Mounds Produced by H2 and C Reduction of Material of Simulated Lunar Composition J.

Optical, X-ray-diffraction and electron-microprobe techniques were used to investigate 0.26 gm of Apollo 14 soil sample 14259. Major element microprobe analyses were made of 470 mineral grains and 388 glass grains. The mineral abundances in the soil are 45% plagioclase, 41% pyroxene, 7% olivine, 3% oxides, 2% K-feldspar; 1% nickel-iron,
