I've created some texture maps for the moon based on NASA maps developed from the Lunar Prospector mission. They show the relative abundance of hydrogen, iron, thorium and potassium, as well as a gravity map. Unfortunately, the Clementine site seems to be still down for mainetnance, or I would have included some from there.
The textures are available at http://www.lns.cornell.edu/~seb/celestia/gallery.html#9 or find your way using the "WWW" button below my sig.
Here's a thumbnail of Celestia using one of them.
