I'd imagine that pollution and erosion would result in a surface of
mineral, rather than organic soil; hence the land cover would be clay,
sand, scree, or bare_rock, depending on the particle size. Even the article
you cite mentions areas eroded to bare rock. These values are all
available for tagging a mineral surface.
