From: Dyke swarms record the plume stage evolution of the Atla Regio superplume on Venus

Fig. 3

Circles indicate the inferred plume head size based on the radius (R) of transition in the dyke swarms, from radiating to linear; dashed where unconstrained (see text for discussion). Additional generalised lines are shown in Fig. S7. The maximum radius of each swarm is: a Ongwuti Mons = >1100 km, b Ozza Mons = >2000 km, c Unnamed Mons = >1100 km, d Maat Mons = >1500 km.
