Campo Del Cielo

Campo Del Cielo meteorites come from the asteroid belt between Mars and Jupiter and are found in Argentina where they originally crashed landed. Their name is a direct translation in Spanish to “field of the sky” because these sky rocks create a intense contrast in the fields they are found in. They are a type of coarse octahedrite meteorites, similar to muonionalusta meteorites except they have much higher iron concentration and shorter cool down periods leading to wider crystallization patterns

They get their smooth irregular look from oblation, which is intense heat melted the irony surface from the friction and pressure of entering Earths atmosphere. Its made of mostly iron and some nickel as well as other trace elements like cobalt, phosphorus, gallium, germanium, iridium, chromium, carbon, sulfur, platinum, copper, gold, ruthenium, palladium and osmium but percentages and elements will vary depending on the specific meteorite. They are estimated to be about 4.5 billion years old and entered earth about 4,700 years ago
