Interestingly, too much of a good thing:

[If instead phyllosilicates formed at or close to the surface, this would require the Mars early atmosphere to be dense. The global change to an acidic environment would then have been coupled to a rapid drop in atmospheric pressure. A number of processes can be invoked to account for it. The hearvy bombardment of Mars, given its low mass, could have resulted in an efficient escape of its early atmosphere (32). The global change could also have been triggered by a rapid drop in the internal dynamo and its resulting magnetic shield, favoring effiecient atmospheric sputtering (32, 33).]

The above is from the article of topic: Sciencemag.org.

More than one factor played a role and beautifully put (interesting way to use "sputtering"). :)
