History
The first record of the Campo was in 1576. A Spanish governor learned of the iron
from the Indians who reportedly believed that it had fallen from heaven. The
governor sent an expedition under the command of one Captain de Miraval who
brought back a few pieces of a huge iron mass he called Meson de Fierro (large
table of iron). The location of the find was the Campo del Cielo (field of the
sky or heaven), a fitting name for the location of a meteorite. Since the
Indians believed that the irons fell from heaven the name may have come from
the meteorites. The area is an open brush-covered plain that has little water
and no other rocks--very good country in which to locate meteorites.
Structure
of the Campo del Cielo
The
Campo del Cielo is described as a polycrystalline coarse octahedrite. At 3 mm
the Widmanstatten bands are thicker than those at Canyon Diablo or Odessa, but
still thin enough to have the same coarse octahedrite classification. The mass
was composed of large austenite crystals from 5 to 50 cm in size. On break-up
the fragments were cold worked like those at Sikhote-Alin and Gibeon. It has
been hypothesized that the original body was tabular in shape and broke up on
entry into the atmosphere. Chemistry of the Campo del Cielo The Campo del Cielo
is classified in Group I, , 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. The important minerals are: · Kamacite--this iron nickel alloy makes
about 90 percent of specimens in finger size and width crystals. Neumann bands
are common. · Taenite and plessite, the other iron-nickel alloy constituents
are found at grain boundaries. · Schreibersite is uncommon. · Troilite is found
aggregates with graphite and silicates.
