Paterae on Triton and Ganymede. (a) Potential lobate flow on Triton, in a chain of volcanic features surrounded by smooth volcanic plains. (b) Topographic depression on Ganymede of 250–1000 m depth and a lobate flow in the interior. (c) Potential flow feature on Ganymede in the bright terrain north of Ta-Urt and east of the crater Mont and extensively resurfaced bright terrain. The white dashed line corresponds to double arcuate irregular scarps and the blue lines to lobate flows. (Credit: Voyager 2, NASA/JPL/USRA).
