摘 要: | The methods of deriving Fe O and Ti O_2 contents from the Clementine spacecraft data were discussed,and an approach was developed to derive the content from the measurements using the Moon Mineralogy Mapper (M~3) instrument on Chandrayaan-1.The density of lunar bedrock was then modeled on the basis of the derived Fe O and Ti O_2 abundances.The Fe O and Ti O_2 abundances derived from the M~3 data were compared with the previous results of the Clementine data and were in good agreement.The Fe O abundance data also agreed well with the Lunar Prospector data,which were used as an independent source.The previous Clementine and newly M~3 derived abundances were compared with the laboratory measured Fe O and Ti O_2 contents in the Apollo and Luna returned samples.The Clementine derived Fe O content was systematically 1%–2%lower than the laboratory measurements in all the returned samples.The M~3 derived content agreed well with the returned Apollo samples and was within±2.8%of the laboratory measurements.The Clementine derived Ti O_2abundance was systematically 0.1%–4%higher than the laboratory measurements of the returned samples.The M~3 derived Ti O_2 agreed well (±0.6%) with the laboratory measurements of the returned samples,except for samples with high Ti O_2content.However,these results should be carefully interpreted because the error range requires verification.No error analysis was provided with the previous Clementine derived contents.
