基于M^3数据的月球澄海区域的铝尖晶石提取及分布探究

Extraction and distribution of aluminum spinel in mare serenitatis area based on M^3 data

尖晶石是岩石成因及条件的一种重要标志,通过对尖晶石来源、成因、结晶以及与共生矿物的关系等的分析,研究相关矿物岩石的成因和起源,对于研究月壳岩石成因与岩浆演化具有重要意义。本文将Mg-Al、Fe-Al尖晶石统称为Al尖晶石,在前人研究基础上,以月球澄海为研究区,讨论澄海区域地形、构造等地质背景,深入对比分析月球尖晶石的遥感光谱特征,采用数理统计的研究方法拟合Al尖晶石的波谱曲线,最终制定了M^3数据提取Al尖晶石的流程。以此为依据,分析了澄海区域M^3数据提取的该区域Al尖晶石分布情况,认为月球中含粉色尖晶石岩石的形成不仅是简单的机械混合,更关键的是产生有着恰好结晶尖晶石的化学组成的岩浆。

Spinel is an important sign of rock genesis and conditions.Through the analysis of spinel origin,genesis,crystallization and the relationship with symbiotic minerals,the study of the origin and origin of related minerals and rocks is of great significance to the study of the origin and magmatic evolution of lunar crust rocks.In this paper,Mg-Al and Fe-Al spinels are collectively referred to as Al spinel.Mare Serenitatis is the research area.The geological background of Mare Serenitatis is discussed.The remote sensing spectral characteristics of lunar spinel are analyzed and compared.The spectral curves of Al spinel are fitted by mathematical statistics.Finally,the process of extracting Al spinel from M^3 data is worked out.Based on this,the distribution of Al spinel extracted from M^3 data in Mare Serenitatis is analyzed.It is believed that the formation of pink spinel rocks in the moon is not only a simple mechanical mixing,but also a key to the formation of magma with exactly crystalline spinel chemical composition.
