Actually, Ed, if you picture small, black balls, highly polished by windblown sand, and spread all over the surface of the sand, you pretty well have it. As Eric's dictionary has said, they are mostly concentrated iron oxide, formed by a concretion process within the soil layer,and then the sandy soil get blown to another part of the desert, leaving the little nodules, or balls, on the surface.
