Huge Campo del Cielo iron meteorite slice, etched and polished on both faces to reveal a handsome Widmanstätten pattern as well as black silicate-graphite-troilite inclusions. The full slice weighs 2,046 grams and measures approximately 314 mm x 223 mm x 4 mm (12.36″ x 8.77″ x 0.15″ or 31.4 cm x 22.3 cm x .4 cm). Campo del Cielo is a class IAB iron meteorite, comprised of about 93% iron and 6.7% nickel, plus small amounts of trace elements including gallium, germanium, cobalt, and iridium. The impact is believed to have occurred approximately 5,000 years ago. The Campo strewnfield is roughly 18 km (11 miles) in length and includes at least 25 distinct craters. It is one of the larger known strewnfields on Earth, and perhaps the single biggest crater field. It is also one of the largest impacts from which actual meteorite specimens have been recovered.
