Abstract
Studies of lunar regolith delivered to Earth by the Soviet automatic station (AS) Luna-24 using highly local electron microscopy methods made it possible to obtain data confirming the migration of sulfur during cooling of metal melts during the process of liquation. As a result, local Fe-S concentrates are formed, and part of the sulfur is displaced outward, forming sulfur shells on the surface of the melt droplets. Their formation on the surface is associated with the evaporation-condensation process during the cooling process of iron balls. The resulting sulfur coatings can be preserved if they are preserved in glass or under thin films of silicate condensate.
期刊介绍:
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
