TheCanyon Diablometeoriterefers to the many fragments of theasteroidthat createdMeteor Crater(also called Barringer Crater),[3]Arizona, United States. Meteorites have been found around the crater rim, and are named for nearbyCanyon Diablo, which lies about three to four miles west of the crater.

History

The impactor fell about 50,000 years ago.[4]Initially known and used by pre-historicNative Americans, Canyon Diablo meteorites have been collected and studied by the scientific community since the 19th century. Meteor Crater, from the late 19th to the early 20th century, was the center of a long dispute over the origin of craters that showed little evidence of volcanism. That debate was largely settled by the early 1930s, thanks to work byDaniel M. Barringer, F.R. Moulton, andHarvey Harlow Nininger.[5][6][7][8][9][10][11]

In 1953,Clair Cameron Pattersonmeasured ratios of thelead isotopesin samples of the meteorite. ThroughU-Pb radiometric dating, a refined estimate of theage of the Earthwas obtained: 4.550 billion years (± 70 million years).[12]
