Origin of Europan surface morphologies IV: evolution of a subsurface saucer-shaped sill and its surface expression, creating pits, domes or small chaos. Upward intrusions into the surrounding ice by freezing water from a sill (a) lead to surface disruption or extrusion [(b) and (c)], to form spots with a subsurface sill [(d) or (e)].
