Shield Plain

Reference work entry
DOI: https://doi.org/10.1007/978-1-4614-3134-3_424

Definition

Lava plain on Venus with scattered small volcanic edifices at a substantially larger area and smaller spatial density than that of shield fields.

Synonyms

Shield terrain (Hansen 2005)

Description

Smooth plains characterized by scattered small (<20 km diameter) shield-like features that are interpreted as volcanic edifices (Hansen 2005; Ivanov and Head 2011; Fig. 1). They resemble  shield fields (Venus), but their morphology is more diverse and they appear more uniformly distributed rather than clustered. Shields in many shield plains occur close to each other and form groups/clusters of structures (Ivanov and Head 2011). Shield plain units typically occur as 10s–100s km wide patches.
