Volcano-Ice Interactions on Earth and Mars

Volcanism is a fundamental planetary process that provides insight into the thermal, surficial, and atmospheric evolution of terrestrial bodies. Interactions between volcanoes and their near-surface water or ice can also produce distinctive landforms that are indicative of environments at the time of the eruption. Here, the products of explosive lava-water interactions in Iceland are compared to analogous structures on Mars to infer martian paleoenvironmental conditions, including ground ice depths and obliquity constraints. The broader implications of Amazonian-age flood lavas in Elysium Planitia are also considered to better constrain the volcanic history of Mars.
