Lunar Minerals
The lunar rocks described in the next chapter are unique to the Moon. Their special characteristics— especially the complete lack of water, the common presence of metallic iron, and the ratios of certain trace chemical elements—make it easy to distinguish them from terrestrial rocks. However, the minerals that make up lunar rocks are (with a few notable exceptions) minerals that are also found ...
متن کاملUnique Spinel-rich Lithology in Lunar Meteorite Alha81005: Origin and Possible Connection to M Observations of the Farside Highlands
Introduction: The discovery of spinel rich rock on the Earth’s Moon, detected by the M near-IR mapping spectrometer on the Chandrayaan-1 spacecraft [1] is among the most intriguing discoveries in a time filled with lunar revelations (e.g., [2]). The M spectrometer discerned several areas on the rim of the far-side Moscoviense basin which had near-IR reflectance spectra characteristic of abundan...
متن کاملLunar Rocks
The Moon, like the Earth, is made of rocks. To learn about the Moon and its history, one has to learn something about lunar rocks—what they are made of, how they are studied and classified, and how our experiences in interpreting rocks on the Earth have been applied to rocks on the Moon. The lunar samples have provided our only direct information about the Moon’s minerals, chemical composition,...
متن کاملAsteroid and Lunar Environment Chamber (alec): Simulated Asteroid and Lunar Environments for Measuring Analog Materials
Introduction: Thermal infrared (TIR) emissivity spectral measurements of planetary surfaces have diagnostic features indicative of rock and mineral compositions. These include: (1) the Christiansen feature (CF), an emissivity maximum resulting from a rapid change in the refractive index at wavelengths just short of the fundamental molecular vibration bands, (2) the reststrahlen bands (RB), the ...
متن کاملPartitioning in REE-saturating minerals: Theory, experiment, and modellmg of whitlockite, apatite, and evolution of lunar residual magmas
We present compositions, including REEs determined by ion microprobe, of apatite and whitlockite in lunar rock assemblages rich in incompatible trace elements. Total concentrations of REE oxides in whitlockites range from 9-13 wt%, and those in apatites range from 0.15 to 1 wt%. Ratios of REE concentrations in whitlockite to those in coexisting apatite range from 10 to 60. The distribution of M...
