    摘要:

    月表矿物的空间分布格局记录了岩浆活动、物质分异及后期撞击改造等关键地质过程,是认识月球演化历史的重要遥感信息基础。本文基于 SELENE(Kaguya)多波段成像仪(Multiband Imager,MI)可见—近红外(415–950 nm)矿物丰度反演产品,结合数字高程模型(DEM)提取的地形参数,构建统一空间尺度的定量分析框架,以研究月海单元内主要矿物相的空间分布及其与形貌特征的关系。选取冯·卡门撞击坑和危海盆地等具有代表性的月球大型撞击构造与月海盆地为研究区,定量刻画近红外敏感矿物丰度与形貌特征在不同地质单元中的空间关联特征。矿物丰度与地形参数在区域尺度上呈现显著的空间集聚特征,且在不同地质背景与构造单元中表现出明显的空间非平稳性,反映了岩浆活动、后续撞击改造及其与古地形协同响应等多过程长期作用的结果,为基于遥感数据的月球表面地质解译与演化历史分析提供了定量依据。

    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.
