Scientific paper

We have used data from the Lunar Reconnaissance Orbiter Diviner lunar radiometer to constrain the composition of iron-rich and iron-poor features within the South Pole-Aitkin Basin (SPA). Diviner has three channels near 8 microns (7.81, 8.28, and 8.55) designed to characterize the Christiansen feature (CF) of lunar soils, which is a well studied indicator of silicate mineralogy. This technique is sensitive to bulk composition including iron-poor minerals such as quartz and feldspar. In contrast, visible and near-infrared spectroscopy can directly identify diverse minerals (especially pyroxene and olivine) but are relatively insensitive to nominally iron-free minerals. Therefore, thermal-infrared and near-infrared datasets are highly complementary. This presentation will describe new constraints on the composition of various sites within SPA that have been previously identified as iron-rich or iron-poor by the Chandrayaan-1 Moon Mineralogy Mapper, including parts of Apollo Crater, Alder Crater, and Mafic Mound. For iron-poor regions, Diviner can put constraints on the presence of high silica minerals and/or the composition of plagioclase. For iron-rich regions, Diviner can help constrain the relative abundance of highland material introduced by impact cratering.
