Maps of Shield Clusters on Venus
There are two types of clusters of small volcanoes on Venus: Shield fields and shield plains. Shield fields have a few hundred edifices erupted close together in a small area. Shield plains have thousands of edifices erupted farther apart and spreading across a large area.
These maps detail four shield fields and three shield plains on Venus. Note the differences in scale.
Shield Field 1, located at 52 degrees south, 302 degrees east.
Shield Fields 2a and 2b, located at 27 degrees north, 136 degrees east.
Shield Field 3, located at 54 degrees north, 168 degrees east.
Shield Plain A, located at 12 degrees north, 132 degrees east.
Shield Plain B, located at 62 degrees north, 150 degrees east.
Shield Plain C, located at 20 degrees north, 136 degrees east.
Legend for all displayed maps.
The following plot shows the number of shields on the y axis versus the area of the cluster on the x axis. Note the four points clustered in the bottom right corner are the shield fields.
