Campo Del Cielo Meteorite
Total Mass: over 100 tons to date
Time of Fall: 4,000 to 6,000 years ago
Location: Campo del Cielo, Gran Chaco Gualamba,
Argentina, about 500 miles north-northwest of
Buenos Aries.
Latitude 27 degrees 39 minutes South,
Longitude 61 degrees 44 minutes West.
Strewnfield: The larger Campo del Cielo meteorites are found in
and around a series of small craters in the southwestern part of the
strewn field. The largest crater is 78 by 65 meters. A smaller one is
56 meters in diameter and 5 meters deep. All together, searchers
have found at least 12 craters.
The main part of the crater-forming mass was found in each of
these craters. This is in contrast to Canyon Diablo and Odessa where the main crater-forming mass is believed
to have vaporized or shattered on impact. In this respect, the field is similar to Sikhote-Alin.
Iron meteorites originate from the molten iron core of what was briefly a planet between Mars and Jupiter. This
planet broke apart during formation approximately 4.5 billions years ago during the birth of the solar system,
and its remnants comprise the asteroid belt
History of The Campo del Cielo Meteorite
The Campo del Cielo meteorite site was first discovered by the Spanish in 1576 in the Gran Chaco Gualamba
region of Argentina, about 500 miles north-northwest of Buenos Aries
The location of the find was Campo del Cielo (field of the heavens), an appropriate name for the location
of a meteorite strewn field. Since the Indians believed that the irons fell from heaven the name is undoubtedly
derived from the meteorites found in this area, which is an open brush-covered plain having little water and few
rocks, making it great meteorite hunting country. Subsequent searches have found Campos over a large
region.
Time of the Fall
Scientists have estimated the date of the Campo del Cielo fall using radiocarbon dating of charred wood found
in the craters. Dates of 5800 years (plus or minus 200 years) and 3950 years (plus or minus 90 years) have
been obtained. These dates are consistent with an Indian lore tradition that the irons fell from the heavens.
Structure of the Campo del Cielo
The Campo del Cielo is a polycrystalline coarse octahedrite. The Widmanstatten bands are thicker than those
at Canyon Diablo or Odessa, but still have the same coarse octahedrite classification.
Composition of Campo del Cielo Meteorites
The Campo del Cielo is classified in Group IAB, , 6.68% Ni, 0.43% Co, 0.25% P, 87 ppm Ga, 407 ppm Ge, 3.6
ppm Ir. Of course, almost all of the remaining portion of the meteorite is iron.
Iron meteorites are extremely rare. Of all of the meteorites that fall on the earth, scientists estimate that only
about five percent are Iron Meteorites.
