Chemical evolution evidence from the planets of Solar System is presented and interpreted in the light of phono-fission reactions. In particular, data coming from different space missions and investigations are reported and compared for the crust of planet Mars. They were made available by NASA during the years 1995–2010. The concentration increments in certain elements (Fe, Cl, and Ar) and the corresponding decrements in others (Ni and K), together with neutron emissions from the Mars largest faults, can be considered as highly correlated phenomena. The presented findings provide a clear evidence of how seismic activity contributed to the Red Planet’s chemical evolution. Analogous evidence regards Mercury, Jupiter, and the Sun itself. The major compositional changes are interpreted according to phono-fission reactions triggered by earthquakes in rocky planets, as well as by atmospheric storms in gaseous planets and in our star. Analogies and differences with respect to the geochemical and geophysical evolution of our planet are emphasized.
