I definitely think there is some resemblance here. However, I have to wonder that if they have been through similar processes, in regards to Dantu, why has a small patch of bright material near the cracks remained while everything else has disappeared, especially a bright central patch of it in the center of the central ridge. One possibility is that it has been recently active, long after most of the bight material was covered up or insolation caused the material to become less reflective. But if it was recently active, then how? Yes, we may be seeing two different stages of the life cycle of some 'volcanic' process. The sparse white spots in Dantu could be the (relatively recent) dying gasps of activity. For an earthly analogy, I'm thinking along the lines of the cinder cones atop the dormant Mauna Kea (Hawaii) vs. the more robust lava flows from the younger Mauna Loa. |
