Аннотация:Micro-Raman spectroscopy of Luna-16 and Luna-24 regolith samples revealed 27 unshocked components, including first-time detections of metallic silicon and arzakite. The study identified sp2-carbon formations (500–1000°C) and proposed a spectral criterion to determine carbon origin (impact, meteoritic, or micrometeoritic). Carbon in Mare Crisium and Fecunditatis regolith was classified as micrometeoritic. Lower carbon content in Luna-24 (2 m depth) suggests increased micrometeoritic bombardment of carbonaceous chondrites in recent time.
