[PPS08-08] High resolution lunar mineral maps using Kaguya Multiband Imager data
Keywords:Lunar, Mineral, map
The mineral maps obtained using the Multiband Imager data shows some notable differences with the mineral maps obtained using Clementine data . The Multiband Imager data suggests there is much more low-calcium pyroxene than what Clementine suggested, and that low-calcium pyroxene is by far the dominant mafic mineral found in the South Pole-Aitken basin. The data also suggests that Mare Serenitatis contains much more olivine than Mare Tranquilitatis, in agreement with Mare Serenitatis having excavated mantle material . The highest olivine abundances (~25 wt.%) are found in the Procellarum KREEP Terrane. High abundances (~50 wt.%) of low-calcium pyroxene and clinopyroxene are also found in the Procellarum KREEP Terrane and in Mare Tranquilitatis. Plagioclase abundances are very high in the Feldspathic Highland Terrane, but mature surface should be analyzed with caution. Indeed, there is currently a mineral identification for every pixel in the Multiband imager data. However, mature surfaces exhibit subdued absorption bands, which can lead to an overestimation in plagioclase abundances, even though we included the presence of SMFe in our modeling. Therefore, the mineral maps presented herein should be interpreted with the aid of the OMAT map. Also, we provide global mineral maps for the complete range of latitudes, but the Multiband Image data has been better calibrated within 50° in latitude , therefore caution should be taken when interpreting regions at higher latitudes.
