Visible in the mosaic are many lava-flooded craters and large expanses of smooth volcanic plains, which appear similar in texture to volcanically emplaced mare deposits on the Moon. At the microsymposium, scientists will gather to compare and contrast volcanism on the Moon and Mercury, including eruption styles and flux, the timing of volcanism, lava compositions and structures, and linkages between volcanism and the impact history and interior evolution of the two bodies.
