Planation surface

[2] Geological maps indicate that planation surfaces may comprise 65% of the landscapes on Saturn's largest moon, Titan,[3] which hosts a hydrological cycle of liquid methane.

In addition to these there are planation surfaces proposed to be formed by cryoplanation, marine processes, areal glacial erosion and salt weathering.

[1] The term planation surface is often preferred over others because some more specific planation surface types and processes remain controversial.

[6] Planation surfaces are often thought to form at distinct base levels with sequences of them representing uplift events.

However the disposition of some so-called planation surfaces may at certain places reflect better the easiness of erosion into different lithologies or structures and may therefore not fit any uplift scheme.
