[Admin]

The world's oldest meteor impact crater is not a crater at all, say scientists of a new study suggesting natural forces put the giant indent into Earth's surface. But the jury is still out.

Just a question of terminology.

Opening paragraph:
"The world's oldest meteor impact crater . . . . . . . . . . . . "

Can a meteor (consumed in the atmosphere) cause a crater by an explosion?
Vide Tunguska and Chelyabinsk.

If it can cause crater, is it an impact crater?

BTW, the paper in Earth and Planetaary Science Letters is correctly entitled:
Stirred not shaken; critical evaluation of a proposed Archean meteorite impact in West Greenland
My emphasis.

There is a lot of info on plate tectonics theory (including 6 references) in Wiki under Maniitsoq structure
