Mössbauer mineralogy on the Moon: The lunar regolith
Hyperfine Interactions, 1998A first-order requirement for spacecraft missions that land on solid planetary objects is instrumentation for mineralogical analyses. For purposes of providing diagnostic information about naturally-occurring materials, the element iron is particularly important because it is abundant and multivalent.

Acta Geologica Sinica - English Edition, 2021
AbstractThe methods of deriving FeO and TiO2contents from the Clementine spacecraft data were discussed, and an approach was developed to derive the content from the measurements using the Moon Mineralogy Mapper (M3) instrument on Chandrayaan‐1. The density of lunar bedrock was then modeled on the basis of the derived FeO and TiO2abundances.

Mineralogic and Petrologic Study of Lunar Anorthosite Slide 15415,18
Science, 1972The anorthosite slide 15415,18 contains > 98 percent subhedral plagioclase (97 mole percent anorthite), two pyroxenes: diopsidic augite (46 percent wollastonite, 39 percent enstatite, 16 percent ferrosilite) with subsidiary (100) lamellae and grains of hypersthene (2.5 percent wollastonite, 58 percent enstatite, 39.5 percent ferrosilite), and traces

[1] The last major phases of lunar volcanism produced spectrally unique high-titanium basalts on the western nearside of the Moon. The Moon Mineralogy Mapper (M3) on Chandrayaan-1 has provided detailed measurements of these basalts at spatial and spectral resolutions necessary for mineralogical interpretation and mapping of distinct compositional units.

Mineralogical studies of lunar rock 12013, 10
Earth and Planetary Science Letters, 1970Abstract A preliminary report is given on the mineralogy of three fragments of lunar rock 12013, 10. In both light and dark areas crystals of plagioclase, alkali feldspar, ilmenite, quartz and other minerals are encrusted with a sugary coating of quartz. This coating also contains dispersed opaque fine particles and small crystallites of SiC, brasses

MINERALOGY, PETROLOGY AND CHEMISTRY OF LUNAR ROCK 12039
Meteoritics, 1972Rock 12039 belongs to the olivine‐depleted group of magmatic rocks characterized by normative and modal SiO2, absence or very low abundance of olivine, and high FeO/(FeO + MgO), Ti/Cr, and CaO/MgO ratios. Clinopyroxenes in this rock show a complex, essentially continuous, compositional zonation from augite cores through ferroaugite to ferrohedenbergite

The Texture and Mineralogy of Lunar Peridotite, 15445,10
The Journal of Geology, 1973Rock fragment 15445,10 consists of dominant olivine (91 mole % Mg₂SiO₄, 0.03 wt % NiO) and aluminous enstatite (91 mole % MgSiO₃, 5 wt % Al₂O₃), together with substantial chrome spinel (14 wt % Cr₂O₃), minor amounts of granular, interstitial plagioclase (94 mole % CaAl₂Si₂O₈), and traces of rutile (?) (1.0 wt % Nb₂O₅) and armalcolite.

Lunar materials: Their mineralogy, petrology and chemistry
Earth-Science Reviews, 1972Abstract The manned Apollo 11, 12, 14 and 15 and the automated Luna 16 lunar missions have provided us with lunar rock and regolith (soil) samples from a number of geologically distinct sites. The mare regions were sampled by Apollo 11, 12 and Luna 16, whereas Apollo 14 landed on a terrain with more relief, the Fra Mauro Formation which represents an
