Iron (IA) coarse Octahedrite with silicate inclusions. This great meteorite was first discovered in 1572 by Spanish explorers in Chaco, Argentina. Thousands of pieces have been found near some impact craters, the largest weighing an immense 35 TONS! These pieces are from a new find, many miles from the original strewnfield. They are being found on a mountainside, several feet underground. They are gorgeous individuals, fully regmaglypted, with no rust! The old Campos are found in the lowlands and have been immersed damp soil for centuries and as a result they are rust balls. These come from a location where there is no standing water thus are in great condition, rivaling Gibeon in character. These are great investment pieces, as they are great looking large meteorites.
