Return to the Moon
silicic lava feature
07/25/11

 

The nature of the terrain jumps out when orbiter camera images are draped over a digital terrain model created with those images. At the center of the province is an irregular depression that might well be a caldera and at its edges are domes with features that suggest they were formed by the intrusion of high-viscosity silicic lava, a type of lava rare on the Moon. Any model of the Moon's thermal evolution must now be able to account for this volcanic province as well as the familiar mare.
