Inhibition of carbonate synthesis in acidic oceans on early Mars

Article Abstract:

Several lines of evidence have recently reinforced the hypothesis that an ocean existed on early Mars. Carbonates are accordingly expected to have formed from oceanic sedimentation of carbon dioxide from the ancient martian atmosphere. It is concluded that extensive interaction between an atmosphere dominated by carbon dioxide and a lasting sulphate- and iron-enriched acidic ocean on early Mars is a plausible explanation for the observed absence of carbonates.

Icy martian mysteries

Article Abstract:

The phenomena of the ice age taking place on two planets, Earth and Mars, have led to the study of its origin. The mystery of the origin of the ice on the planet Earth is discussed.
