Steep-Sided Dome (Venus)

Reference work entry
DOI: https://doi.org/10.1007/978-1-4614-3134-3_545


A volcanic edifice with characteristic high-angle margins and relatively horizontal upper surface displaying a circular to subround planform morphology, although the original planform morphology may be modified and adjacent domes may overlap.



 Pancake dome; SSD


Volcanic domes are typically circular overall in planform with steep margins and relatively horizontal upper surfaces (Figs. 1 and 2). Planform morphology commonly (>80 %) displays modification due to slope failure, which can produce radial protuberances and may be associated with debris aprons (Bulmer and Guest 1996; Bulmer and Wilson 1999; Gleason et al. 2010; Bulmer 2012). Upper surfaces of domes may be somewhat concave or convex and may display a wide range of features, including pits; radial, concentric, and polygonal fractures; and peaks (e.g., Bulmer and Guest 1996; Stofan et al. 2000; Gleason et al. 2010). Steep-sided domes range from 1 to...
