Here's an opportunity to purchase one of our 3 g meteorite specimens, from the Chaco and Santiago del Estero provinces of Argentina. You will receive a single piece from one of the examples, as illustrated in images, each one varies in size and weight only very slightly. These meteorites are of a recent batch found close to the Chaco meteor fall, entering Earths atmosphere between 2,200 to 2,700 BC. These meteorites were formed 4.5 billion years ago in the solar system nebula. Part of the iron/nickel core of an asteroid, they were ejected into space when it collided with another body and broke into pieces. They fell to earth about 4,200 to 4,700 years ago; the el Chaco fragments rediscovered in 1969.

Located on a mountainside a few miles from the original fall, strewn field of fragments which struck the earth and deposited several feet underground. The largest piece discovered weighed approximately 35 tons; these were termed large tables of iron, being so huge. When indigenous Indian natives first witnessed the meteorite fall in 1572, they explained the occurrence as a fall from heaven to the local authority. The governor of the region sent an expedition under the command of one Captain de Miraval to report the discovery.

Our specimens are fine fragments between 0.3mm and 10mm, fully regmaglypted, with no rust. The historical finds of the Campo del Cielo fall were originally discovered in the lowlands of the region, where concentrations of damp soil persisted. As a result, they tended to be more susceptible to decay. The meteorite fragments offered here come from a location with no significant concentrations of standing water, therefore preserving these rare once shattered and melted fragments without incurring the effects of rust.

Chemistry: The Campo de Cielo is classified in the group I, 6.68% Ni, 0.43% Co, 0.25% P, 87ppm Ga, 407 ppm Ge, 3.6ppm Ir. The remaining portion of this particular meteorite is iron.

Age: (Reported discovery, 1572) Space age 4.5 billion years.
Fall: 2,200 – 2,700 years BC.
