Abstract
Aimed to clarify the shower of Campo del Cielo with respect to the presence of a large number of hexahedrites in the shower of Campo del Cielo, we have studied a piece that belongs to the Campo del Cielo meteorite Fall by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), chemical analysis, Mössbauer spectroscopy (MS), and optical metallography. The studies showed that it is an HIIA iron hexahedrite meteorite of 94.6Â wt% Fe, 5.4Â wt% Ni and 370Â ppm of C, consisting of a kamacite matrix with small inclusions of iron-nickel phosphides. We have found Neumann bands differentiated from scarce taenite streaks and found that taenite is a path walk for corrosion. We also mention the approximate present localization of some of the principal pieces of the fall.
