Degassing of volatiles in the geological history of Mars
I obtain an estimate of the total mass of degassed volatiles on Mars and the distribution of degassing in time. The amount ofvolatiles degassed in all the history of Mars is of the order of 3.73x1020 kg, i.e. 16 000 times the current Martian atmosphere. Thebulk of the degassing occurred in Early, Mi...

| Sumario: | I obtain an estimate of the total mass of degassed volatiles on Mars and the distribution of degassing in time. The amount ofvolatiles degassed in all the history of Mars is of the order of 3.73x1020 kg, i.e. 16 000 times the current Martian atmosphere. Thebulk of the degassing occurred in Early, Middle, and Late Noachian, and in Early Hesperian. Degassing was monotonicallydecreasing in the last five epochs, from Early Hesperian to Late Amazonian. The amount of liquid water at the surface in the pastwas very little or none, thus the existence of life is doubtful. |
