Description
[edit]Formation
[edit]The shield plains surface is covered with small shield like features ranging from a few kilometers to greater than 10 kilometers in diameter. They are believed to be of volcanic origin. These shields typically found in close proximity with each other and will form groups of structures. The transition between the shields and the plains in between the shields is morphologically smooth and sometimes contains wrinkle ridges.
