Abstract月球玄武岩的矿物组成反映了源区的化学成分和岩浆的结晶环境.了解月海玄武岩的矿物组成对研究月球岩浆演化具有重要意义.选择澄海为研究区,综合利用光谱、地形、元素等多源遥感数据将澄海划分为55个地质单元.基于月球矿物制图仪(Moon Mineralogy Mapper,M^3)数据,提取84条新鲜撞击坑光谱曲线,计算吸收中心波长、波段面积比等光谱参数.通过分析光谱吸收特征,获得澄海玄武岩镁铁质矿物的空间变化特征.研究结果表明,澄海玄武岩镁铁质矿物主要为高钙单斜辉石.澄海中部和南部地质单元具有较低的橄榄石/辉石比,东部和西部地质单元具有较高的橄榄石/辉石比.从东、西部到中部区域,橄榄石/辉石比例逐渐降低.
