Near-infrared spectra of ferrous mineral mixtures and methods for their identification in planetary surface spectra
Bell, James F.; Cloutis, Edward A.; Mann, Paul +1 more
Iron-bearing minerals are a major component of planetary surfaces, and many can be identified by their characteristic absorption bands in the near-infrared (NIR). Here we present laboratory NIR spectra of a wide range of common Fe-bearing minerals (e.g., olivines, pyroxenes), glasses, and mineral/glass mixtures. We then use this suite of spectra t…
Lunar polar craters - Icy, rough or just sloping?
Smith, David; Eke, Vincent R.; Bartram, Sarah A. +2 more
Circular Polarisation Ratio (CPR) mosaics from Mini-SAR on Chandrayaan-1 and Mini-RF on LRO are used to study craters near to the lunar north pole. The look direction of the detectors strongly affects the appearance of the crater CPR maps. Rectifying the mosaics to account for parallax also significantly changes the CPR maps of the crater interior…
Mineralogy of young lunar mare basalts: Assessment of temporal and spatial heterogeneity using M3 data from Chandrayaan-1
Murty, Sripada V. S.; Srivastava, Neeraj; Varatharajan, Indhu
A comparative assessment of the mineralogy of young basalts (∼1.2 Ga to ∼2.8 Ga) from the western nearside, Moscoviense basin, and the Orientale basin of the Moon has been made using Level 2 Moon Mineralogy Mapper (M3) data from the Chandrayaan-1 mission. Spectral data characteristics of the individual units have been generated from fre…
Volcanism on farside of the Moon: New evidence from Antoniadi in South Pole Aitken basin
Senthil Kumar, P.; Sruthi, U.
The lunar surface is characterized by asymmetric distribution of its volcanic deposits. The nearside contains about 90% of the mare basalts, while there are a few on the farside with some are in the South Pole Aitken (SPA) basin, which is the largest and oldest impact basin on the Moon. Although the mare volcanism on the nearside of the Moon has b…
Western Oceanus Procellarum as seen by C1XS on Chandrayaan-1
Howe, C. J.; Kellett, B. J.; Crawford, I. A. +3 more
We present the analysis of an X-ray fluorescence (XRF) observation of the western part of Oceanus Procellarum on the Moon’s nearside made by the Chandrayaan-1 X-ray Spectrometer on 10th February 2009. Through forward modelling of the X-ray spectra, we provide estimates of the MgO/SiO2 and Al2O3/SiO2 rati…
