IRON, COARSE OCTAHEDRITE – IAB-MG GRAN CHACO, ARGENTINA (27°28' S, 60°35' W)

Thousands of years after landing on Earth, Campo del Cielo (“Valley of the Sky”) meteorites were first written about in 1576 by Spanish explorers in Argentina when their unearthly origins were not yet understood. It was a “Campo” that was the first large meteorite ever displayed in a major museum — the British Museum of Natural History — and several large Campo del Cielo masses can be found today in the finest museums in the world. Few, if any, possess as finely articulated regmaglypts (the flight markings acquired from burning through Earth’s atmosphere) as seen on the example now offered.

Campo del Cielo meteorites formed as the result of two asteroids colliding at cosmic velocity in interplanetary space. When a large fragment from one of these asteroids hit Earth’s upper atmosphere more than 4,000 years ago, the immense pressure exerted on the mass caused it to explode into thousands of pieces. The larger meteorites struck the ground at such a high velocity that an array of at least 26 impact craters formed, the largest a football field in diameter.
