Iron coarse octahedrite - IAB-MG
Meteor Crater, Coconino County, Arizona - (35° 3'N, 111° 2'W)
Embedded in the matrix of Canyon Diablo meteorites are graphite nodule inclusions. It was the ejection or weathering of these inclusions that is responsible for the sockets that provide the distinctive character to select Canyon Diablos (see lot 49015). Graphite inclusions are typically the size of a walnut. The current offering, however, is far larger. This is a complete slice of the largest graphite nodule on record, whose main mass is in the Arizona State University Meteorite Collection - one of the world's finest. It was the monumental force of the asteroid's impact (the asteroid was traveling at a cosmic velocity of roughly 10 miles-per-second) that resulted in its nickel-iron matrix being injected into, and fully penetrating, the graphite - a phenomenon richly in evidence. Exquisitely ornamental, this is an extraordinary artifact of a cataclysmic collision frozen in time. 168 x 132 x 5mm (6.66 x 5.25 x 0.25 inches) and 337.8 grams (0.75 pounds).
