Hi all, long time no see.
Yet another theory to explain the origin for the bedrock encountered by Opportunity. I first heard of this new theory from Universe Today; http://www.universetoday.com/2009/02/16/ne...t-mars-equator/ An abstract is available at http://www.nature.com/ngeo/journal/vaop/nc...bs/ngeo438.html The theory is interesting, but I would really be interested to know how it explains the spherules seen by Opportunity not to mention the vugs. Thoughts any one? -------------------- |

ngunn, could you elaborate on what a "closed isobar" means in this context? I'm having some difficulty picturing the topology of a blister of liquid beneath an ice-sheet. I wonder if this model has any implications for the expected local or regional topology of resulting deposits on the surface today - might the outlines of this area be evidenced in remaining terrain? The article mentions Antarctic examples of this phenomena but if I submit to the call of the Google, I'll never get this pile of work done...
