Abstract

SNC meteorites are Martian rocks that provide valuable information about the atmospheric composition of Mars over time. These meteorites experienced significant shock during the impact that released them from Mars, and during the flight through the Martian atmosphere some of the gases were retained in the melted shock-altered glasses. As using different radiogenic systems can precisely date such shock processes, SNC achondrites can be considered time capsules capable of providing significant insight into the atmospheric evolution of Mars. Different SNCs were released by impacts at different times, having then different atmosphere-implantation ages, so in practice we can obtain clues on the composition of Mars’ atmosphere at different times. Taking this information into account, we have developed a 1D model of the evolution of Martian Mars’ atmosphere mass, near surface temperature and pressure.
