    Abstract:

    The spatial distribution of lunar surface minerals provides essential constraints on magmatic activity, material differentiation, and subsequent impact modification, and is fundamental for reconstructing the Moon’s evolutionary history from remote-sensing observations. In this study, visible–near infrared (415–950 nm) mineral abundance products derived from the Multiband Imager (MI) onboard SELENE (Kaguya) were integrated with digital elevation model (DEM)–derived topographic parameters to conduct a quantitative, unified-scale spatial analysis of mineral–geomorphology relationships within lunar mare units. Representative large-scale impact structures and mare basins, including the Von Kármán crater and Mare Crisium, were selected as study areas to characterize the spatial correlation between near-infrared-sensitive mineral abundances and geomorphological features across different geological units. The results reveal significant regional-scale spatial clustering of mineral abundances and topographic parameters, along with pronounced spatial non-stationarity across varying geological and structural settings. These spatial patterns reflect the coupled long-term effects of magmatic activity, subsequent impact modification, and their interaction with pre-existing topography, thereby establishing a quantitative framework for lunar surface geological interpretation and evolutionary analysis using remote-sensing data.
