Abstract—
Our study of the spatial and genetic relationship between coronae and lobate plains allows us to draw two important conclusions. (1) About 17% of all volcanic coronae of Venus are sources (coronae–sources) of young lavas that form lobate plains of the Atlian period. A small portion of coronae–sources in the total population of coronae reflects the decrease in the formation rate of mantle diapirs. (2) The area of lobate plains associated with a particular corona and the area of the corona itself are negatively correlated. These relationships allow the existence of only two models for the final stages in the evolution of mantle diapirs. Having analyzed both of these models, we suppose that, during the Atlian period in the geologic history of Venus, either a single zone of neutral buoyancy existed or the lithosphere base was located at approximately the same level.
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.
