Planetary scientists from Brown University have proposed a new scenario for the formation of ancient clay minerals on Mars that, if shown to be true, could rewrite the early history of the red planet.

Clay minerals on Mars may have formed in primordial steam bath

Academics / Astronomy : EurekAlert: Space

(Brown University) New research suggests that the bulk of clay minerals on Mars could have been formed as the planet's crust cooled and solidified, not by later interactions with water on the surface as has long been assumed.

Primordial clays on Mars formed beneath a steam or supercritical atmosphere

Academics : Nature

On Mars, clay minerals are widespread in terrains that date back to the Noachian period (4.1 billion to 3.7 billion years ago). It is thought that the Martian basaltic crust reacted with liquid water during this time to form hydrate...
