About this work
Tyrrhenus Mons is one of the oldest Martian volcanoes. Tyrrhena Fossae is the largest of the channels dissecting the volcano. As well as being one of the oldest volcanoes, it is made of layers that include volcanic ash rather than just basaltic flows. This difference is evident in how the volcano is being eroded, creating broad intersecting sinuous channels. On Earth basaltic flows form broad shield volcanoes like Hawaii.
