abstract |
We present X-ray fluorescence observations of the lunar surface, made by the Chandrayaan-1
X-ray Spectrometer during two solar flare events early in the mission (12th December
2008 and 10th January 2009). Modelling of the X-ray spectra with an abundance algorithm
allows quantitative estimates of the MgO/SiO<sub>2</sub> and Al<sub>2</sub>O<sub>3</sub>/SiO<sub>2</sub>
ratios to be made for the two regions, which are in mainly basaltic areas of the lunar
nearside. One of these ground tracks includes the Apollo 14 landing site on the Fra
Mauro Formation. Within the 1 σ errors provided, the results are inside the range
of basaltic samples from the Apollo and Luna collections. The Apollo 14 soil composition
is in agreement with the results from the January flare at the 1 σ uncertainty level.
Discrepancies are observed between our results and compositions derived for the same
areas by the Lunar Prospector gamma-ray spectrometer; some possible reasons for this
are discussed. |
