Discovery of HgS in the Lunar Regolith from Apollo-17 Samples

摘要

A 3-mu m particle of HgS is found by electron microscopy techniques in studying the lunar regolith samples delivered by Apollo 17. It might have been preserved due to a thin cover of highly siliceous glass, having protective functions. This particle was likely formed from a gaseous phase by the condensation of Hg and S vapors.
