Meteoritical Society meeting, Dublin (Ireland), 27-31 Jul 1998Lawrence D. J., Feldman W. C., Binder A. B., Maurice S., Barraclough B. L., and Elphic R. C. (1998) Mapping the elemental composition of the Moon: First results from the Lunar Prospector gamma-ray spectrometer. Eos ...
The elemental composition of the lunar surface provides insights into mechanisms of the formation and evolution of the Moon1,2. The chemical composition of lunar regolith have so far been precisely measured using the samples collected by the Apollo, Luna and Chang’e 5 missions, which are from ...

Chemical changes induced in aragonite using treatments for the destruction of organic material Treatments used to destroy or remove organic material prior to chemical analyses of carbonate material alter the elemental composition of aragonite. To ass... LA Woronow - 《Chemical Geology》 被引量: 34发...
of lherzolites are reported (LREE-depleted La/Sm(N)= 0.11–0.37 × Cl and LREE-enriched, La/Sm(N)= 1.88–15.72 × Cl). The depleted lherzolites have variable range in Li concentration (olivine: 2.1–5.4 ppm; opx: 1.1–2.3 ppm; cpx: 1.0–1.8 ppm) and in Li isotopic composition (...

Effects of Pulse Bias Duty Cycle on Composition, Structure and Hardness of Ti–Cu–N Nanocomposite Films Deposited by Pulse Biased Arc Ion Plating Hard nanocomposite Ti–Cu–N films were deposited on high-speed-steel (HSS) substrates by pulse biased arc ion plating with a single multi-component...
A new concept of a space experiment with a γ-ray spectrometer onboard a mobile spacecraft has been proposed for studying the elemental composition of the Moon, Mars, and other celestial bodies without an atmosphere or with a thin atmosphere using the method of tagged charged particles of ...
compositioncometsHigh dispersion photographic spectra of three Leonid and five Perseid meteors are used to derive relative abundances of nine chemical elements in the radiating meteoric vapors and in the meteoroids. Al and Ca were found to be incompletely evaporated in the main spectral component at ...
