This suggests that the major axis of the crater field is not yet well determined. The major axis of the crater field as we know it extends along N63Â☎, but the azimuths of infall determined by excavation of Craters 9 and 10 are N83.5Â☎ and N75.5Â☎, respectively. This suggests that when the parent meteoroid broke apart, the resulting fragments diverged from the original trajectory in inverse relation to their masses and did not undergo size sorting due to atmospheric deceleration. The largest craters are near the center of this ellipse. Reflecting the low angle of infall, the crater field is elongated with apparent dimensions of 3 Ã- 18.5 km. Relative to the horizontal, the angle of infall was Ëœ9Â°. The craters were formed by multi-ton fragments of a type IA meteoroid with abundant silicate inclusions. The fall occurred Ëœ4000 years ago into a uniform loessy soil, and the craters are well enough preserved so that some of their parameters of impact can be determined after excavation. The Campo del Cielo meteorite crater field in Argentina contains at least 20 small meteorite craters, but a recent review of the field data and a remote sensing study suggest that there may be more.

Our results led us to conclude that the pre-atmospheric radius might have been approximately 2 m. L.Ĭosmogenic Be-10, Al-26, Cl-36, Ca-41, and Ni-59 were measured in the Campo del Cielo iron meteorite. Cosmogenic Radionuclides in the Campo Del Cielo Iron Meteorite
