The other rocky planets in our solar system show a common feature. Within giant craters

caused by impacts, there's evidence of volcanic activity, which made scientists wonder. Can

big impacts actually cause volcanic eruptions? And has that scenario ever happened here?

To find out, scientists went to one of the few massive craters on Earth not erased by plate tectonics,

the Sudbury crater in Canada.

Sudbury is a 1.85 billion years old impact structure.

Teresa Ubide, a geochemist at the University of Queensland in Australia.

Sarbury was generated when a bollite of 10 to 15 kilometers in diameter hit Earth. And what happened

was it obviously generated a large basin and also melted the crust on top of the earth at that time

and generated a massive melt pool, 2.5 kilometers in depth.

But Ubedee and her colleagues found that the impact did more than that.

It also seems to have triggered eruptions of magma that came from deep in the mantle.

The evidence lies in the fact that the chemistry of the lava that erupted at Sudbury changed over time.

At first, it matched the surface rocks, suggesting it was just from local melting.

But as the eruptions continued, the lava appeared to come from deep in the mantle,

suggesting the impact stirred things up inside the earth.
