释义
Barringer Crater

Astronomy
  • See Meteor Crater.


Space Exploration
  • An impact crater near Winslow in Arizona, caused by the impact of a 50-m iron meteorite about 50 000 years ago. It is 1.2 km in diameter and 200 m deep, and the walls are raised 50–60 m above the surrounding desert.

    It is named after the US mining engineer Daniel Barringer who proposed in 1902 that it was an impact crater rather than a volcanic feature, an idea confirmed in the 1960s by US astronomer Eugene Shoemaker, who studied the crater for his doctoral research at the California Institute of Technology.
