A Closer Look At The Surface Of Mars

The nature of many of the rocks and materials on the surface of Mars remains mysterious. Volcanism has played an important role in forming many of the surface materials on Mars, and water has played a role in the alteration of many of those volcanic rocks and ashes. A geologic process that could have contributed to the formation of many of the volcanic materials is “hydrovolcanism,” the explosive interaction of rising magmas with water at, or near, the surface either...
