Result is nice, but explanations are a bit short 
I love plasma, applied to a layer mask there is no better way to get an eroded look.
Even better, if you use the same plasma for the bump map and the erosion mask (may require Color>Invert) the erosion aligns with the bumps, which is where it would happen in real life. The ned result feels fairly realistic.
