The role of episodic overturn in generating the surface geology and heat flow on Enceladus

Nimmo, Francis; O'Neill, Craig

The Saturnian satellite Enceladus is enigmatic in that its geologically active south polar region shows high heat flows and geysers not seen elsewhere on the satellite at present; its heavily deformed surface shows an episodic age distribution; and the current observed heat loss exceeds the long-term tidal equilibrium heat production by a factor o…

Planetary science: Tectonic overturn on Enceladus

Helfenstein, Paul

The south pole of Saturn's icy moon Enceladus is anomalously warm, geologically youthful and cryovolcanically active. Episodic convective overturn explains how the moon's modest sources of internal heat can be channelled into intense geological activity.
