What causes fading?

When it comes to projection and slide storage in general I am more
concerned with slide fading rather than heat.  Which portion of the
radiation spectrum causes fading in slides?  Why is there a (reported)
difference in the rate of fading between Kodachrome and E6 emulsions in
projection?  Why is the Kodachrome more stable in (dark?) storage than E6?
