Karazin popup.description2 A new technique that interpolates available lunar prospector gamma-ray spectrometer (GRS) data using clementine uvvis spectral reflectance images was obtained. The main idea is to use low resolution GRS data a "Ground truth" to establish relationships linking optical mineralogy and geochemical information maximizing the respective correlation coefficients. Then the relationships and Clementine UVVIS data are used to derive elemental abundance maps with significantly improved spatial resolution, up to 10 times. The main limitation of the technique is its dependence on how well the abundance of the elements correlates with the Clementine UVVIS data. The technique can also be applied to analysis of coming D-CIXS/Smart-1 and AMIE/Smart-1 data to increase resolution of lunar compositional maps. As an illustration of the suggested technique, maps for the elements Fe, Ti, Al, Ca, Mg, and O with pixel size 15 km x 15 km are presented. The Fe and Ti distributions very resemble to the maps obtained with the well-known method by Lucey et al. Our new maps for the elements Fe, Ti, Al, Ca, Mg, and O appear to be informative. For instance, the map of oxygen abundance demonstrates an anomaly in the crater Tycho, and the map of calcium shows fairly low mare/highland contrast. The maps of Fe and Al contents show for highland regions slight variations related to maturity degree. Reliability of this relation is confirmed with lunar sample data. The reason of the correlation between chemical composition and exposition age of the lunar surface can be the global transport of the lunar surface material due to meteorite impacts.
