Abstract
The degassing of material from the carbonaceous chondrite Dar al Gani (DaG) 190 (type CO3) was studied using a specially designed experimental setup. The results of experimental investigations on heating and isothermal holding (pyrolysis) of meteorite samples are presented, with the composition of released gases determined by gas chromatography. Raman spectra and IR spectra were obtained for both the primary material of DaG 190 (CO3 type) and after annealing at three temperatures: 200, 500, and 800°C. Based on these data, the thermal transformation process of the asteroid material—the parent body of the meteorite—was traced. A comparison was made with the degassing results of another carbonaceous chondrite, Allende (type CV3). Cosmochemical applications to the accretion processes of terrestrial planets are discussed, as well as the role of carbonaceous chondrites as sources of water, gases, and volatile compounds for the Moon and early Earth.
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.
