DescriptionThe Gibeon is composed almost entirely of iron-nickel alloy. Since the first report of large masses near the town of Gibeon in 1838, many thousands of pieces of have been found over a large area of southern Namibia. It is likely that a large meteor broke up upon hitting the atmosphere, scattering fragments widely over the Earth below. The area over which they fell is called a strewn field. The Gibeon strewn field is enormous: about 20,000 square kilometers. It is believed that the iron-nickel of meteorites such as the Gibeon had separated from 'lighter' elements to form dense molten cores of asteroids by processes similar to those that formed the Earth's core.
