The terrestrial age of this iron meteorite is thought to be 50-60 thousand years. It is a polycrystalline, inclusion-rich coarse octahedrite.
Type: Octahedrite, coarse
Ocotillo
One mass of 28.57 kg was found by Bill Hanna about 5 miles N of Ocotillo. Analysis, 7.01% Ni, 0.47% Co, 112 ppm Cu, 74 ppm Ga, 13.9 ppm As, 2.6 ppm Ir, 4.9 ppm Pt, 1.65 ppm Au, John T. Wasson, Institute of Geophysics and Planetary Physics, UCLA, Los Angeles, California 90024, USA. Additional analysis, 7.4% Ni, 0.43% Co, 0.46% P, and information, Charles F. Lewis, Center for Meteorite Studies, Arizona State University, Tempe, Arizona 85287, USA. Main mass, James Schwade, 969 South Chicago Ave, Kankakee, Illinois 60901, USA.
Odessa
The Odessa crater field has several craters ravaged by excavating and weathering; the largest is 530 feet.
Copiapo
Numerous masses were brought to Copiapo since 1863: some, owing to interchange of labels by G.Daubr
Deport
Masses of 2.7kg, 1.3kg, and 0.9kg were found in 1926 one mile E of Deport; at least 23 more masses totalling a further 10kg were found later, M.H.Hey, Cat. Met., 1966, p.133. Described and analyzed, 7.9% Ni, C.Palache and F.A.Gonyer, Am. Miner., 1932, 17, p.357. Further analysis, 8.11% Ni, 69.9 ppm Ga, 255 ppm Ge, 2.2 ppm Ir, J.T.Wasson, Icarus, 1970, 12, p.407. Description, V.F.Buchwald, Handbook of Iron Meteorites, Univ. of California, 1975, p.531. Pb isotopic composition, C.G
Campo Del Cielo
First documented by the early Spanish explorers in 1576 Campo del Cielo is aptly translated “Field of the Sky”. The meteoritic iron was later used in making weapons for the war of independence from Spain. It is a polycrystalline, coarse octahedrite with silicate, graphite, and troilite inclusions of significant size.
Canyon Diablo
Canyon Diablo meteorites come from the most famous impact crater in the world; Meteor Crater, Arizona. These iron meteorites are classified as IA, coarse octahedrite. Many contain inclusions of graphite. When a graphite inclusion pops out of the host meteorite it is called a graphite nodule. Another interesting fact about Canyon Diablo is the occurrence of carbonados or black diamonds formed by impact on earth or in space. These meteorites are typically characterized by classic meteorite features like sharp ridges, holes and bowls.
