Lunar Crust: Structure and Composition
Science, 1972Lunar seismic data from artificial impacts recorded at three Apollo seismometers are interpreted to determine the structure of the moon's interior to a depth of about 100 kilometers. In the Fra Mauro region of Oceanus Procellarum, the moon has a layered crust 65 kilometers thick.

Chemical Composition of Lunar Material
Science, 1970Chemical and emission spectrographic analyses of three Apollo 11 samples, 10017-29, 10020-30, and 10084-132, are given. Major and minor constituents were determined both by conventional rock analysis methods and by a new composite scheme utilizing a lithium fluoborate method for dissolution of the samples and atomic absorption spectroscopy and ...

Geochimica et Cosmochimica Acta, 2003
Abstract We present new compositional data for six feldspathic lunar meteorites, two from cold deserts (Yamato 791197 and 82192) and four from hot deserts (Dhofar 025, Northwest Africa 482, and Dar al Gani 262 and 400). The concentrations of FeO (or Al2O3) and Th (or any other incompatible element) together provide first-order compositional ...

Lunar highland meteorites and the composition of the lunar crust
Geochimica et Cosmochimica Acta, 1991Abstract Major, minor, and trace element data obtained by neutron activation techniques and by spark source mass spectrometry (SSMS) on two lunar meteorites MAC88104 and MAC88105 are reported. Both MAC samples were also analysed for their contents and isotopic compositions of rare gases.

Elemental Composition of Lunar Surface Material
Science, 1970Elemental abundances, so far obtained, derived from the analysis of Apollo 11 lunar material are reported. Similarities and differences exist between lunar material, the eucritic achondrites, and the augite achondrite Angra dos Reis, the analysis of which is also reported.

Transbaikal State University Journal, 2021
The problem of compositional analysis of extraterrestrial crystalline rocks in the study of celestial bodies is considered. Since most of the bodies, terrestrial planets and their surrounding objects may contain clinopyroxenes, it is possible to study the temperature and pressure of rock formation in certain areas according to the state of these ...

Lunar Rock Compositions and Some Interpretations
Science, 1970Samples of igneous "gabbro," "basalt," and lunar regolith have compositions fundamentally different from all meteorites and terrestrial basalts. The lunar rocks are anhydrous and without ferric iron. Amounts of titanium as high as 7 weight percent suggest either extreme fractionation of lunar rocks or an unexpected solar abundance of titanium.

Multiple reservoirs of volatiles in the Moon revealed by the isotopic composition of chlorine in lunar basalts [PDF]
Geochimica Et Cosmochimica Acta, 2019 The isotopes of chlorine (37Cl and 35Cl) are highly fractionated in lunar samples compared to most other Solar System materials. Recently, the chlorine isotope signatures of lunar rocks have been attributed to large-scale degassing processes that ...

Lunar Composition by Scintillation Spectroscopy
IRE Transactions on Nuclear Science, 1962Information on the composition of the moon and its past history is being sought through measurements of the spectrum of the gamma rays emerging from the lunar surface. The detector is a 3 × 3 in. CsI-plastic scintillator phoswich feeding a 32-channel analyzer weighing 5 pounds.

Lunar Composition and Lunar Light in Stoic Philosophy
Apeiron, 2017AbstractThis paper attempts to reconstruct the Stoics’ theory (or theories) of the nature of the moon and its illumination from the fragmentary, and sometimes apparently conflicting, evidence. It reveals how the Stoics accounted for the distinctive characteristics of the moon by intricately utilising their mixture theory (especially κρᾶσις) and their ...
