This sounds like something that is going to be of paramount importance on Mars
when we go there. The dust there is supposedly of even greater fineness (since
its been blowing around for billions of more years, you would think so) than the
clay dust where you are at, so getting it out of any water deposits we find is
going to be an interesting problem.
