Scientific paper

Knowledge of the distribution of Fe and Ti within the principal lunar terranes can help us understand the bulk composition of the Moon. Materials on the surface that carry information about the interior include: (1) the maria, with varying Fe and Ti concentrations, (2) deep impact basins that may have exposed material from the lower crust and upper mantle, and (3) regions rich in KREEP basalts. Consequently, data that provide a global and/or high-spatial resolution assessment of lunar Fe and Ti are especially valuable in studies of lunar geochemistry. The Clementine spectral reflectance (CSR) data have been used to derive maps of FeO and TiO2. Because CSR spatial resolution approaches 100 m, such maps are potentially invaluable in lunar studies. The CSR technique depends on mineralogy, and while it has been constrained by returned lunar sample geochemistry, the question remains whether the results are accurate far from the Apollo and Luna landing sites. In this paper we discuss some of the results of a comparison of the Lunar Prospector neutron spectrometer (LPNS) observations and the CSR Fe and Ti maps.
