Oldest Impact Crater on Earth Discovered
http://news.yahoo.com/oldest-impact-...162802443.html

Scientists think it was formed 3 billion years ago by a meteorite 19 miles (30 kilometer) wide — which, if it hit Earth today, would wipe out all higher life. The crater is so wide that it would reach the edge of space 62 miles (100 km) above Earth if stood on end.

. . . .
The area in Western Greenland has deposits of Ni and Pt. I wonder if it's from the same source as the crater in Sudbury, Ontario, which is considered to be only 2 (+/-) billion years old.

...an impact from a meteorite that may have contained valuable metals.
Doesn't that mean that some valuable metals may have come as a result of meteorite impacts?
