On Io, Jupiter's moon, extreme tidal forces produce intense volcanic activity. But because of its distance from the sun the surface is quite cold (-130 C) and the volcanic gasses released literally freeze out of the atmosphere, producing drifts of sulfur dioxide snow, which can be revaporized by flows of molten sulfur from the volcanoes. So Io has a sulfur cycle.
