I posted the following in sci.geo.geology, but I do not feel very competent
on the 'chemical' contents and would very much appreciate your comments

I'm tempted to take another shot at the nature of the cohesive Mars-soil.
Electrostatic attraction! ... as put by others earlier.
When you break a rock as happens in mechanical wear and tear of 'weathering'
.... wouldn't the nature of this incidence provide one positive and one
negative broken bond?
On Earth all broken bonds are considered negative - due to the chemically
aggressive oxygen of our atmosphere?.. But this point does not apply on
so it's minute soil-particles may thus have mutual electrostatic
attractions - Voila -
This attraction may be the more pronounced the finer the particles - and as
I have posted earlier: there is no obvious 'drain' for the fine grains
produced by the Mars' 'weathering'.
