Exploring the tectonic histories of Saturn’s ocean worlds: from deep time to now.

Observations of Enceladus’s tectonic structures suggest that Enceladus may have expereienced punctuated episodes of tectonic activity. Similar populations of fractures on Dione and Rhea may also preserve evidence of varied stress histories within the fracture patterns expressed on their surfaces. Similarities and differences of the preserved fracture histories on these will inform the complex tectonic histories and geologic activity on these ocean worlds.
