Ancient volcanic explosions shed light on Mercury’s origins

Mercury was long thought to be lacking volatile compounds that cause explosive volcanism. That view started to change when the MESSENGER spacecraft returned pictures of pyroclastic deposits — the telltale signature of volcanic explosions.

The findings suggest Mercury not only had volatiles but held on to them for longer than scientists had expected.

PROVIDENCE, R.I. [Brown University] — The surface of Mercury crackled with volcanic explosions for extended periods of the planet’s history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn’t supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed. (more…)
