Seems to be a lot of dispute on this subject... I think it's ice from the interior, but what does everyone else think?
Edit: This world seems very complex so the question could perhaps be phrased as 'which of these options is most responsible for the Iapetan dichotomy?' |

True, but Earth's Moon is thought to be an artifact of a massive collision (therefore technically of exogenic origin?)...not quite the same situation as would be expected for a satellite of a gas giant.
