Abstract

Abstract

Morphologic, structural and compositional characteristics of the lunar soil returned by Chang'E-5 provide invaluable insights into the origin of the lunar soil and the evolution history of the Moon' s surface. Using scanning electron microscopy-energy dispersive spectrometer and micro-Raman spectrometer, the scooped lunar soil sample CE5C0400 (YJFM00403) was systematically investigated. The lunar soil consists of a variety of particles, including single minerals such as plagioclase, clinopyroxene and olivine, basaltic clasts, agglutinates and glass beads. The surface features and microstructures of the particles are characterized by diverse, micrometer to nanometer scale morphological features in the form of fragmentation, surface attachment and microcratered and sputtered structures. The morphological features of Chang'E-5 lunar soil have recorded a wealth of information about the complex processes of space weathering dominated by micrometeorite impacts. Repeated impacts led to the fragmentation and fining of lunar soil particles, whereas impact-induced local melting welded the particles, accompanied by the formation of micrometer to submicrometer metal spheres through decomposition of iron-bearing minerals. Repeated cycles of these complex processes thus have resulted in significant changes in the particle sizes and mineral components of the lunar soil.
