Impact Structures

The best-preserved impact crater on Earth, gouged out ~50,000 years ago by the Canyon Diablo iron meteorite — the site where the impact origin of craters was first firmly established.

A well-studied mid-sized impact crater in Germany whose shocked minerals and impact glass were used by Apollo astronauts as a training ground for recognising impact features on the Moon.

One of the oldest and largest known impact structures, whose ancient impact melt hosts some of the world's richest nickel and copper ore deposits.

The largest confirmed impact structure on Earth, the deeply eroded remnant of a crater formed roughly two billion years ago by one of the largest impacts in the planet's history.
