A type of mountain on Io.
Subtypes
- (1)
Steep-sided shield volcanoes (Schenk et al. 2004) with surface slopes greater than 1° (Williams et al. 2011):
Shield volcanoes (Io) or tholi of which three have been identified (Williams et al. 2011)
Steep-sided domes (Io) of which two adjacent examples have been found
- (2)
Low shield volcanoes (Schenk et al. 2004), p. 425 paterae (volcano-tectonic depressions) that include several active volcanic centers (Io). Most of these have very shallow slopes of 0.1° and maximum elevations of about 2 km (Williams et al. 2011).
Formation, Composition
These are volcanic mountains of presumably silicate or sulfur-rich materials (Williams et al. 2011).
