It is suggestive that the two major deposits of Unobtanium that we're told of correspond with particularly obvious bits of Eywa. That's also why I was suggesting a biological origin for the stuff; it's a bit of a leap from what we're told in the film, but Eywa may be subtly (or not so subtly) working with biological systems on Pandora.
