I think there is no chance that the blue ring is caused by geyser activity. We don't know what the composition of the particles is.
It's funny that this research got started by something we didn't see.
This model can be transferred directly to what we now see in Uranus, although we still need to understand the details of the process.
We went out in October to image both rings and we simply couldn't see the outer one. We should have easily seen it if it was a normal ring. The interesting part was that the outer ring was the one that was the brighter one in the Hubble images.
When dust is smaller than or comparable to the wavelength of light, the reflected color is dominated by particle size effects rather than the intrinsic color of the material.
