Description: weight: 32g Size: 3.5*2.2*1.7(cm) International name: Campo del cielo Chemical composition of Campo: Average content: nickel 6.67%, cobalt 0.43%, phosphorus 0.25%, gallium 87ppm, germanium 407ppm, iridium 3.6ppm, and the rest is iron (approximately 92.5%). Introduction: Campo meteorite was found at the junction of Chaco Province and Santiago del Estero Province Province in Argentina, about 1000 km away from Buenos Aires, the capital of Argentina. Campo meteorite was scattered in 3 × At least 26 craters have formed in a 20 kilometer area, with the largest crater being 115 × 91 meters. The meteorite iron in the crater and surrounding areas was discovered and reported by local indigenous residents in 1576. It is known that the total weight exceeds 100 tons, with the largest piece being 37 tons, making it the second largest meteorite in the world. More than 4000 years ago, a huge meteorite rain fell in the northeast of Argentina, scattered in the 60 square kilometer area, leaving more than 20 craters, the largest of which is 115 m x 90 m. As early as the 16th century, the indigenous people of Argentina began to use Campo del Cielo Iron meteorite to make weapons. At that time, the Spanish colonialists also went to collect a large number of Iron meteorite. They thought it was the iron ore brought by the volcanic eruption, but it was not confirmed as Iron meteorite until 1788. Many meteorite fragments with a total weight of over 100 tons have been found in the falling area. In 1969, people found a 37 ton body (Figure 7.3, top right), which is the second largest meteorite in the world after Hoba Iron meteorite. Campo del Cielo Iron meteorite contains a large number of silicate inclusions, which is also the main reason for the meteorite to explode into many pieces in air burst. Campo del Cielo Iron meteorite is a coarse Octahedron structure, and its chemical type is IAB (Ni6.7%). By testing the ℃ age of the charred trees beneath the meteorite, it was determined that the meteorite fell approximately 4700-4200 years ago
