[New, stunning evidence based on finding atmospheric argon 40 indicates that Titan has experienced volcanic activity generating not lava, as on Earth, but water ice and ammonia.

Thus, while many of Earth's familiar geophysical processes occur on Titan, the chemistry involved is quite different. Instead of liquid water, Titan has liquid methane. Instead of silicate rocks, Titan has frozen water ice. Instead of dirt, Titan has hydrocarbon particles settling out of the atmosphere, and instead of lava, Titanian volcanoes spew very cold ice.]

From Adam's last ESA link.

So, it does have something in common with Neptune's moon, Triton: Cryovolcanism (if so, where's the source/s ;) Although, that may be where the similarities end.

[The hard ridges were not made of rock, as similar features are on Earth, but frozen water ice.

Some of the images showed white streaky patterns believed to be exposed water ice sliced through by rivers.]
