AB: In this work I made an evaluation of the quantity of atmosphere lost by Mars by oxidation of the surface in his geological history. In a previous work I calculate the quantity of igneous rocks generated in the diverse Martian epochs. In this work I use that previous calculus and calculate the quantity of oxygen that reacts with these new rocks. The maximum oxidation of the soil occurred in the middle Noachian and the present rate of oxidation is the minimum.
